Compliance and Restrictions



This fuse is designed to help in protecting against motor overload, ground fault, and short-circuits. It also helps to improve blackout prevention and offers protection against burnout from single phasing on three phase systems.

The overload element provides protection against low-level overcurrent of overloads, and will hold an overload 5 times greater than the ampere rating of the fuse for a minimum of 10 seconds.
