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.
