## 6.3 mm x 32 mm ferrule and axial lead, high breaking capacity, high I[2] t ceramic tube fuses 

The MDH fuse can withstand large surge events without opening 

## **Product description:** 

- Higher I[2] t and higher breaking capacity than most ¼” ferrule fuses 

- 600Vac rated ferrule fuse that provides both primary and secondary circuit protection 

- High voltage surge withstand capability 

- 20 cycles of 1.2/50 μs -8/20 μs, 20 kV/10 kA surge 

- UL248-14 compliant 

- Ferrule and axial lead options 

- Halogen free, lead free, RoHS compliant 

## **Features and benefits:** 

- The high I[2] t can allow higher inrush currents without operating to reduce nuisance openings, but still provide excellent short circuit protection 

- The MDH fuse can withstand large surge events without opening, allowing overvoltage devices to operate as designed. 

- With a 600Vac rating in a ¼” diameter, a single part number can be applied in platforms with multiple system voltages
