Features:
• Protect lighting, heating and other circuits not subject to temporary
surges and where available short-circuit currents are relatively low
• NOS one-time fuses do not have any appreciable degree of time-
delay and thus should not be specified in circuits where large
transients or motor overloads occur. Use Bussmann advanced
protection FUSETRON™ LPS-R or ultimate protection Low-Peak™
LPS-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
