## **Features:** 

- Industry’s only UL Listed and CSA Certified fuse with a 300kA Vac interrupting rating that exceeds requirements for virtually all applications 

- Current-limitation for maximum short-circuit protection and reduced arc flash hazard 

- Easy selective coordination with all Low-Peak fuses using simple 2:1 ampacity ratio 

- No damage” Type “2” protection for IEC and NEMA starters when properly sized 

- High inrush current motor protection 

- Time-delay permits 130% FLA sizing for back-up motor overload protection and single-phasing protection 

- Low watt loss power consumption 

- Electrically isolated end caps for additional safety 

## **Applications:** 

- Feeder and Branch Circuits 

- Motors 

- Transformers 

- Solenoids 

- General Purpose Circuits
