308 Series 30V Intrinsically Safe Fu ~~se~~ 

## **Pb** ~~**RoHS** @{__|cSAMus €) [ES ie~~ 

## ~~**Description**~~ 

The 308 Series offers a range of surface mountable encapsulated fuses certified as intrinsically safe components that can be used in hazardous locations. Ideal for use in oil, gas, mine, chemical, pharmaceutical and process industries, the 308 Series surface mountable fuse was designed to limit the energy and temperature generated during its operation. The fuse design and its encapsulant are suitable for use in intrinsically safe apparatus and associated apparatus for peak voltage not exceeding 30V. 

## ~~**Features** Lo~~ 

- Surface Mountable 

- Surface Mountable • Fully compatible with • Encapsulated and sealed lead-free solder alloys and (0.7mm minimum) higher temperature profiles 

- • Designed for operation in associated with lead-free a range of hazardous area assembly applications requiring • Global hazardous locaiton 30V peak (haz loc) certificaitons

**Notes:** 

**1.** The fuse must be mounted so that creepage and clearance distances aren’t impaired in any way. 

**2.** The fuse is suitable for use in intrinsically safe equipment and associated apparatus for voltage not exceeding 30V peak. 

**3.** Maximum surface temperature rise at 170% rated current: 250-375mA = 23°C, 500mA = 35°C, 750mA = 53°C, 1A = 38°C, 1.25-1.50A = 96°C. 

**4.** Minimum Cold Resistance at -30°C is available upon request.

## **Notes:** 

**1.** Re-rating depicted in this curve is in addition to the standard re-rating of 20% for continuous operation. 

**Example:** For continuous operation at 55°C, the fuse should be rerated as follows: I = (0.80)(0.90)IRAT = (0.72)IRAT 

**2.** The temperature rerating curve represents the nominal conditions. For questions about temperature rerating curve, please consult Littelfuse technical support for assistance.
