Their design and construction were optimized to provide: - Low energy let-through (I2t) - Low watts loss - Superior cycling capability - Low arc voltage - Excellent DC performance North American style fuses provide an excellent solution for medium power applications. While there are currently no published standards for these fuses, the industry has standardized on mounting centers that accept Bussmann fuses. ## **Voltage Rating** All Bussmann North American style fuses are tested at their rated voltage. Bussmann should be consulted for applications exceeding those values. ## **Accessories** **==> picture [217 x 96] intentionally omitted <==** **----- Start of picture text -----**<br> ||||| |---|---|---|---| |Voltage|AC|DC|Ampere Range| |130|X|X|1000-4000| |150|X|X|70-1000| |250|X|X|35-2500| |500|X|X|35-1600| |600|X|—|1-1000| |700|X|X|5-1200| |800|—|X|40-600| |1000|X|—|35-2000| **----- End of picture text -----**<br> External and internal open fuse indication is available for selected portions of the North American line.

The minimum voltage for operating the indicator is 20V. ## Type T Indicator The indicator is situated on one cover plate with a cover plate tag to accommodate an auxiliary switch. The minimum voltage for operating the indicator is 20V. A special low voltage indicator (1.5V) is available on request. ## Type K Indicator This indicator is situated on the fuse body. It is covered by an adaptor for snap-on mounting of an auxiliary switch. The operating voltage of the indicator is 1.5V. As a matter of safety, the factory mounted adaptor must not be removed from the fuse. ## Microswitch The Typower ZILOX fuses with either type T indicator or type K indicator can be equipped with a microswitch for remote electrical indication of fuse operations. All microswitches have one normally open and one normally closed contact. Ratings are 2A, 250 Vac. |**Microswitch**|**6.3 x 0.8 mm**<br>**Lugs**|**2.8 x 0.5 mm**<br>**Lugs**|**Indicator**<br>**Type**| |---|---|---|---| |170H0235|≈||T| |170H0236|≈||T| |170H0237||≈|T| |170H0238||≈|T| |170H0069|≈||K| |**Size**|**DIN 43 653**<br>Ge<br>~~esGf~~|**DIN 43 653**<br>Ge<br>~~esGf~~|**DIN 43 620**<br>Ge<br>~~Gf~~|**DIN 43 620**<br>Ge<br>~~Gf~~|**French Style**<br>GO<br>~~Gf~~|**French Style**<br>GO<br>~~Gf~~|**Flush End**<br>GO<br>~~Gf~~|**Flush End**<br>GO<br>~~Gf~~|**US Style**| |---|---|---|---|---|---|---|---|---|---| ||**Type T**<br>~~es~~<br>~~i~~|**Type K**<br>~~Gf~~<br>~~ee~~|**Type T**<br>~~Gf~~<br>~~ee~~|**Type K**<br>~~Gf~~<br>~~es~~|**Type T**<br>~~Gf~~|**Type K**<br>~~Gf~~|**Type T**<br>~~Gf~~|**Type K**<br>~~Gf~~|**Type K**| |000|170H0236<br>170H0238<br>~~es~~<br>~~i~~<br>~~es ee~~|~~Gf~~<br>~~ee~~<br>~~ee ee~~|170H0236<br>170H0238<br>~~Gf~~<br>~~ee~~<br>~~ee~~|~~Gf~~<br>~~es~~|~~Gf~~|~~Gf~~|~~Gf~~|~~Gf~~|| |00|170H0235<br>170H0237<br>~~i~~<br>~~es ee~~<br>~~es~~|~~ee~~<br>~~ee ee~~<br>~~eses~~|~~ee~~<br>~~ee~~<br>~~es~~|~~es~~<br>~~es~~|~~es~~|~~es~~|170H0235<br>170H0237<br>~~es~~|~~es~~|| |1*|170H0235<br>170H0237<br>~~es ee~~<br>~~es~~<br>~~ee~~|170H0069<br>~~ee ee~~<br>~~eses~~<br>~~es~~|170H0235<br>170H0237<br>~~ee~~<br>~~es~~<br>~~ee~~|~~es~~<br>~~ee~~|170H0236<br>170H0238<br>~~es~~<br>~~ee ee~~|170H0069<br>~~es~~<br>~~ee~~|~~es~~<br>~~ee~~|170H0069<br>~~es~~|170H0069| |1|170H0235<br>170H0237<br>~~es~~<br>~~ee~~<br>~~ee~~|170H0069<br>~~eses~~<br>~~es~~<br>~~es ee~~|~~es~~<br>~~ee~~<br>~~ee~~|~~es~~<br>~~ee~~<br>~~ee~~|170H0236<br>170H0238<br>~~es~~<br>~~ee ee~~<br>~~ee~~|170H0069<br>~~es~~<br>~~ee~~<br>~~ee~~|~~es~~<br>~~ee~~<br>~~ee~~|170H0069<br>~~es~~|170H0069| |2|170H0235<br>170H0237<br>~~ee~~<br>~~ee~~<br>~~ae~~|170H0069<br>~~es ~~<br>~~es ee~~<br>~~es ee~~|170H0235<br>170H0237<br> ~~ee ~~<br>~~ee~~<br>~~ee~~|~~ee ~~<br>~~ee~~<br>~~es ee~~|170H0236<br>170H0238<br> ~~ee ee~~<br>~~ee~~<br>~~ee~~|170H0069<br>~~ee~~<br>~~ee~~|~~ee~~<br>~~ee~~|170H0069|170H0069| |3|170H0235<br>170H0237<br>~~ee~~<br>~~ae~~<br>~~es~~|170H0069<br>~~es ee~~<br>~~es ee~~<br>~~GGG~~|170H0236<br>170H0238<br>~~ee ~~<br>~~ee~~<br>~~GGG~~|~~ee ~~<br>~~es ee~~<br>~~GGG~~|170H0236<br>170H0238<br> ~~ee ~~<br>~~ee~~<br>~~GGG~~|170H0069<br> ~~ee~~<br>~~GGG~~|~~ee~~<br>~~GGG~~|170H0069<br>~~GGG~~|170H0069| |4|~~ae~~<br>~~es~~<br>~~es~~|~~es ee~~<br>~~GGG~~<br>~~Ge~~|~~ee ~~<br>~~GGG~~<br>~~Ge~~|~~es ee~~<br>~~GGG~~<br>~~QQ~~|~~ee~~<br>~~GGG~~<br>~~QQ~~|~~GGG~~<br>~~QQ~~|~~GGG~~<br>~~QQ~~|170H0069<br>~~GGG~~<br>~~QQ~~|| |23|~~es~~<br>~~es~~|~~GGG~~<br>~~Ge~~|~~GGG~~<br>~~Ge~~|~~GGG~~<br>~~QQ~~|~~GGG~~<br>~~QQ~~|~~GGG~~<br>~~QQ~~|~~GGG~~<br>~~QQ~~|170H0069<br>~~GGG~~<br>~~QQ~~|| |24|~~es~~<br>~~Pf~~|~~Ge~~<br>~~Pf~~|~~Ge ~~<br>~~Pf~~|~~QQ~~<br>~~Pf~~|~~QQ~~<br>~~Pf~~|~~QQ~~<br>~~Pf~~|~~QQ~~<br>~~Pf~~|170H0069<br>~~QQ~~<br>~~Pf~~|| _**BIF document: 720034**_ **58** _For complete specification data, visit our Web site at_ _**www.bussmann.com** or call Bussmann Information Fax ~ 314.527.1450_ ~~eee~~ 727 Nia Bussmann® a) ® TAL ## Square Body – Accessories **Fuse Bases (Blocks)** ## DIN 43 653 Fuse Bases **==> picture [44 x 7] intentionally omitted <==** **----- Start of picture text -----**<br> DIN 43 653<br>**----- End of picture text -----**<br> For the Typower ZILOX fuses according to DIN 43 653, the following fuse bases are available: **==> picture [213 x 52] intentionally omitted <==** **----- Start of picture text -----**<br> ||||| |---|---|---|---| |Part|Max.|Rated|Center| |Number|Voltage|Current|Distance| |170H3003|1000V|630A|80mm| |170H3004|1000V|1250A|80mm| |170H3005|1400V|630A|110mm| |170H3006|1400V|1250A|110mm| **----- End of picture text -----**<br> The fuse bases rated 1250A can also be used for the fuses with higher rated current if the maximum load current is derated according to the table below: **==> picture [215 x 110] intentionally omitted <==** **----- Start of picture text -----**<br> ||||| |---|---|---|---| |Fuse Rating|Max.

**General Information** Designed and tested to: - BS 88: Part 4 - IEC 269: Part 4 - U.L. Recognized Bussmann offers the industry’s widest range of British style semiconductor fuses and accessories. Bussmann British style products use innovative arc quenching techniques and high grade materials to provide: British style fuses are typically found in equipment manufactured in the United Kingdom or British Commonwealth countries. However, North American manufacturers have begun to specify British style fuses — particularly in UPS applications at 240 volts or less — to take advantage of their size, performance and cost benefits. ## **Voltage Rating** All Bussmann British style fuses are tested to IEC 269: Part 4. This standard requires a test voltage which is 5% higher than the rated voltage. In North America, fuses are required to clear only their rated voltage. ## **Accessories** Trip-indicator fuses are available for use in parallel with the main fuse. Indicator fuses can be attached to the associated fuselink, or mounted separately in panel-mounted fuseclips. In addition, a push-on adaptor and microswitch attachment are available, to provide remote indication.

**General Information** Select fuses designed and tested to: - IEC 269: Part 4 - U.L. Recognized Bussmann offers a full line of ferrule style (cylindrical and clip-mounted) fuses, designed and tested to meet standards and requirements in various locations around the world. Their unique design and construction provide: - Superior cycling capability - Low energy let-through (I2t) Ferrule fuses provide an excellent solution for small UPS, small AC drives and other low power applications where space is at a premium. ## **Voltage Rating** All Bussmann ferrule fuses — except 660 volt — have been tested at their rated voltage. The 660 volt ferrule fuse has been tested to the IEC 269 standard, which requires clearing at the rated voltage +10%. ## **Accessories** Ferrule fuses may be mounted in fuseclips, fuseholders, fuseblocks or fused switches. A variety of products are available to suit most end-use requirements. _For complete specification data, visit our Web site at_ _**www.bussmann.com** or call Bussmann Information Fax ~ 314.527.1450_ **79** Bussmann® **==> picture [35 x 36] intentionally omitted <==** ## Ferrule ## **FWA 150V 5-60A** ® |**FWA 150V**|**FWA 150V**|**5-60A**|**5-60A**|**5-60A**|||||®| |---|---|---|---|---|---|---|---|---|---| |**Electrica**||**l Characteristics**|||**Ordering Information**|||**Dimensions**|**Curves**| |**Size**|**Rated**<br>**Current**<br>**RMS-Amps**|**I2t (A2S)**||**Watts**<br>**Loss**|**Part**<br>**Number**|**Carton**<br>**Qty.**|**Carton**<br>**Weight**<br>**(kg)**|**Figure**<br>**Number**|**See Page**<br>**or**<br>**(BIF #)**| |||**Pre-arc**|**Clearing**<br>**at 150V**||||||| |10 ≈ 38mm<br>(⁄‹Ω£™∑)|5<br>10<br>15<br>20<br>25<br>30|1.6<br>3.6<br>14<br>33<br>58<br>100|8<br>16<br>55<br>130<br>220<br>400|1<br>2.7<br>3.3<br>3.8<br>4.9<br>4.9|FWA-5A10F<br>FWA-10A10F<br>FWA-15A10F<br>FWA-20A10F<br>FWA-25A10F<br>FWA-30A10F|10|0.100|Fig. 1|page 91<br>(35785317)| |21 ≈ 51mm<br>(⁄‹Ω¡§∑)|35<br>40<br>45<br>50<br>60|75<br>100<br>130<br>170<br>250|800<br>1000<br>1300<br>1600<br>2400|4.5<br>5.1<br>6<br>7.3<br>8.0|FWA-35A21F<br>FWA-40A21F<br>FWA-45A21F<br>FWA-50A21F<br>FWA-60A21F|10|0.600|Fig. 1|page 91<br>(35785305)| - Interrupting rating 100kA RMS Symmetrical. 1 kg = 2.2 lbs. 1 lb = 0.45 kg - Watts loss provided at rated current. - Consult Bussmann for DC ratings. - See accessories on page 90. ## Dimensions Fig. 1: 5-60 Amp Range **==> picture [455 x 352] intentionally omitted <==** **----- Start of picture text -----**<br> Metric Inches<br>A C<br>Part Number A B C A B C<br>FWA 5A10F-30A10F 38.1 9.5 10.3 1.5 0.375 0.406<br>FWA 35A21F-60A21F 50.8 15.9 20.6 2.0 0.625 0.811<br>Dimension in mm.<br>1mm = 0.0394∑ 1∑ = 25.4mm<br>B<br>Electrical Characteristics<br>Total Clearing I [2] t Arc Voltage Power Losses<br>The total clearing I [2] t at rated voltage and This curve gives the peak arc voltage, Watts loss at rated current is given in<br>at power factor of 15% are given in the UL, which may appear across the fuse the electrical characteristics.
