FNQ-R-12 TIME DELAY FUSE

Description

The FNQ-R-12 is a 12A Class CC time-delay (slow-blow) fuse from the Eaton Bussmann FNQ-R series. It is a dual-element, current-limiting fuse designed for protection of control transformers, industrial control circuits, branch circuits, and sensitive electrical equipment where temporary inrush currents occur during startup.

Its time-delay characteristic allows it to withstand short-duration overloads while still providing fast protection against dangerous short-circuit faults.
