General Information:
• Protect lighting, heating and other circuits not subject to tem-
porary surges and where available short-circuit currents are
relatively low.
• 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 Buss FUSETRON®
or LOW-PEAK® dual-element, time-delay fuses.
• For general purpose circuits, size at ampere rating of circuit.
• For motor circuits, size at 300% to 400%.
