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

timedelay and thus should not be specified in circuits where

large transients or motor overloads occur. Use Bussmann series

advanced protection FUSETRON FRS-R or ultimate protection

Low-Peak LPS-RK dual-element, time-delay fuses.

•

For general purpose circuits, size at amp rating of circuit

•

motor ampacity tables 430.247 to 430.250, per 430.6(A)(1)
