140MT Motor Protection Circuit Breakers

Our Bulletin 140MT motor protection circuit breakers (MPCBs) provide magnetic short-circuit and thermal overload protection up to 40A. Bulletin 140MT motor circuit protectors offer enhanced ratings that enable assembled starters to be applied without additional branch circuit protection. Tap conductor ratings allow smaller conductors in group motor installations, saving you money. Motor circuit protectors are applied with a separate overload relay for three-component starters.
