1 Choose a circuit breaker with time-current curves comparable to a Time Delay Fuse.
2 “Time-Delay” fuses are UL class “RK5” .
3 “Normal Operating” (general purpose – no intentional delay) fuses are UL class “K5” (up to and including 60 amp), and UL class “H” ( 65 amp and
above).
Y
Caution: Failure to follow these fuse and circuit breaker recommendations could create an electric shock or fire hazard.
