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 time-delay and thus should not be specified in circuits where large transients or motor overloads occur. NLS series fuses provide low cost protection for general purpose feeder and branch circuits when available short circuit currents are less than 50,000 amperes.
