Eaton Bussmann NON20 General Purpose Fuse

The NON-20 is a 20A general-purpose fuse designed to provide basic protection for lighting, heating, and other circuits that are not subjected to temporary surges. It protects circuits with relatively low short-circuit currents and does not feature time-delay; therefore, it should not be used in applications with large transient voltages or motor overloads. For enhanced protection, consider using Bussmann's FUSETRON™ FRN-R or the Low-Peak™ LPN-RK dual-element, time-delay fuses.
