50A 250V OT Fuse

Protect lighting, heating and other circuits not subject to temporary surges and where available short-circuit currents are relatively low.
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 Buss FUSETRON or LOW-PEAK dual-element, time-delay fuses or other brand equivalent fuse.
