Allen-Bradley Overloads & Motor Protectors

Allen-Bradley overloads and motor protectors in this catalog include 140MT motor protection circuit breakers with matching auxiliary contacts, 193 electronic overload relays, and related heater elements used with NEMA starters. 140MT catalog strings after the series prefix encode frame size and trip current (for example C3E-B or C3E-C amp bands); 193-1E numbers encode sensing range. Match the trip band and mounting style to the failed protector or the motor FLA on the nameplate before ordering. Series pages for 140MT and 193 list the same stock in tighter groups. East Coast Compactor keeps common protectors and overload relays in stock and ships from Northwood NH. Parts are sold by an independent supplier; ECC is not an authorized Rockwell distributor and does not provide manufacturer warranty.
