FAQ

A faulty circuit breaker will often fail to reset after it has tripped, or it may trip repeatedly under a normal load. If you notice the button remains loose, fails to 'click' into place, or if there is no continuity across the terminals when the breaker is in the 'on' position, it is time for a replacement.
This thermal circuit breaker is rated for 30 Amps and is compatible with both 125V and 250V AC electrical systems.
Installation typically requires a screwdriver to remove the housing panel and a pair of needle-nose pliers to disconnect and reconnect the spade terminals. Ensure the equipment is completely disconnected from the power source before beginning.
These breakers are designed to protect equipment from overcurrent conditions. Frequent tripping is often caused by a short circuit in the wiring, a failing motor drawing excessive current, or simply wear and tear on the internal bimetallic strip over many years of operation.
Before installing the new breaker, inspect the wiring connected to the old unit for signs of heat damage, melting, or corrosion. If the wires are damaged, they must be trimmed back to clean copper or replaced to prevent the new breaker from failing prematurely.
