1025HC25-RTR

## **1025HC High current, surface mount fuses** 

## High current, fast-acting, surface mount fuses in a compact size 

## **Product description:** 

Eaton’s Bussmann® series 1025HC SMD fuses offers high current ratings in a compact size: 

- 20, 25, 30, 40, 50 A 

Provides high current protection for primary and secondary protection: 

- 125 Vac (20 A to 40 A) 

- 72 Vdc (20 A to 40 A) 

## **Features and benefits:** 

   - Fast-acting performance 

   - Highest available current rating in a traditional SMD fuse 

   - Higher I[2] t than the leading competitors in the same package, allowing for higher inrush currents and fewer nuisance openings 

   - UL Recognized for US and Canada PSE certified (20 A – 30 A) 

- 60 Vdc (50 A) 

- RoHS compliant, lead free and halogen free construction 

The compact 1025HC offers a significant space savings over other fuses with similar current ratings. 

A compact size allows for space savings in the application: 

- 10.0 mm X 3.2 mm (20 A to 30 A) 

- 12.4 mm x 4.5 mm (40 A to 50 A) 

- Operating temperature of -55 °C to +125 °C ensuring protection in harsh climates 

- 72 Vdc rating on the 20 A thru 40 A make this ideal for protection of telecom circuits
