Features

• Protect lighting, heating and other circuits not subject to temporary surges and where available short-circuit currents are relatively low

• NON one-time fuses do not have any appreciable degree of timedelay and thus should not be specified in circuits where large transients or motor overloads occur. Use Bussmann series advanced protection FUSETRON™ FRN-R or ultimate protection Low-Peak™ LPN-RK dual-element, time-delay fuses.

• For general purpose circuits, size at amp rating of circuit

• For motor circuits, size at 300% to 400% according to the NEC® motor ampacity tables 430.247 to 430.250, per 430.6(A)(1)

Recommended fuse blocks :

• 1-, 2- and 3-pole modular fuse blocks up to 600 amps — see data sheet no. 10487

• 1-, 2- and 3-pole modular power distribution fuse blocks up to 60 amps — see data sheet no. 10490
