ABB KXTCMOE110-125 Motor Protection Relay Module

ABB KXTCMOE110-125 is a stored-energy motor operator for ABB SACE Tmax XT molded-case circuit breakers in the XT2–XT4 family. Supplied from 110–125 V AC or DC control power, this module uses a motor to cock the breaker’s operating spring, enabling remote or automatic closing and opening of the XT MCCB under protection relay commands or control logic. When energised, the MOE provides the energy to move the mechanism quickly and consistently, supporting fast isolation during fault conditions and reliable reclose cycles as part of a coordinated protection scheme. It is designed to be integrated with the XT2–XT4 frame-size Tmax XT breakers, preserving manual operation as a backup and simplifying installation in panelboards, motor control centers, and distribution boards that require motor-operated switching. Typical applications include industrial energy distribution where remote control, PLC integration, or automatic sequential switching is required, such as motor feeders, selectivity schemes, and backup power configurations. The 110–125 V rating covers common control power supplies in many regions, and the part number KXTCMOE110-125 identifies it as ABB’s stored-energy motor operator accessory for the Tmax XT family.
