## **Specifications:** 

## **Ratings** 

- Volts 

- 600Vac 

- 300Vdc (15 & 20A) 

- Amps 1⁄4-30A 

- IR 

- 200kA Vac RMS Sym. 

- 20kA Vdc (15 & 20A) 

## **Agency information** 

- UL[®] Listed, Std. 248-4, Class CC, Guide JDDZ, File E4273 

- CSA[®] Certified, Class CC CSA, Class 1422-01, File 53787–HRC-MISC 

- CE 

- RoHS compliant* 

- FNQ-R-1⁄4 not RoHS complaint. 

## **Features:** 

- Provides 10X better current limitation to help prevent equipment damage caused by shortcircuit events. 

- 200kA interrupting rating complies with NEC[®] Section 110.9 for today’s large capacity systems. 

- Fast-acting fuse helps prevent equipment damage caused by short-circuit events. 

- Rejection type fuse fits both standard and rejection-style holders. 

- The Class CC FNQ-R Limitron fuse meets the needs of control circuit transformer protection. 

- FNQ-R fuses can be sized according to NEC[®] and UL requirements and still allow the high inrush currents, with significantly more timedelay than the UL minimum value of 12 seconds at 200% for Class CC fuses. 

- Ideal for critical industrial or commercial applications that have specific current limitation requirements.
