TIME DELAY FUSE FRS-R-40

Product Description

The FRS-R-40 is a dual-element, current-limiting time-delay fuse that safely handles temporary overloads (like motor starting current) while quickly interrupting dangerous short-circuit faults.

Its dual-element design allows:

Short-term overload tolerance
Fast response during fault conditions

This makes it ideal for protecting motors, transformers, and control circuits without nuisance tripping.
