## **Features:** 

- Meets basic protection requirements of NEC[®] , Canadian Electrical Code (CEC), UL and CSA. 

- Most economical overcurrent protection solution compared to circuit breakers. 

- For use in various non-demanding, general purpose applications. 

- Compact branch-circuit units with high interrupting rating and current-limitation. 

- With up to a 600V rating, they can be used in 120/208V, 120/240V, and 277/480V circuits. 

- Size rejection by length helps prevent overfusing. 

- Fuses 7 amps and above have a degree of overload time-delay that permits them to pass temporary overloads.
