The MOPLG120C module is a G Series, L-frame motor operator module manufactured by the Eaton Corporation. It is rated 100 to 125 Volts DC or at 110 to 127 Volts AC and 2 Amps of inrush current. The dimensions of this unit are 8.25 (width) x 8.25 (height) x 9.5 (depth) inches and its net weight is 1.9 kilograms. This unit is ideal for applications that require the remote operation of Eaton molded case circuit breakers. The MOPLG120C motor operator module is mounted directly on the circuit breaker (over the switch) to mechanically switch from the OFF state to the ON state and vice-versa without manual operation. The RESET option is accessible remotely. All motor operator accessories from the Eaton Corporation have been certified by Underwriters Laboratories (UL), the Canadian Standards Association (CSA) and the European Conformity (CE).

Apart from its remote capabilities, the MOPLG120C motor operator module also supports local operation through the keyhole on its front panel. This module houses a motor that is connected to its cam drive to control the handle of the circuit breaker. It is equipped with current limiting switches and relays to prevent power conditions that can damage a motor or reduce its lifespan. This motor operator is fitted out with an easily accessible push-to-trip button to trip the breaker manually. The MOPLG120C motor operator module can be used to achieve standard load transfer switching in applications where it is used in conjunction with another circuit breaker and operator motor module from the same series connected to this unit’s circuit breaker through a mechanical interlock. A small window on the side of the keyhole indicates its operating status and a padlock can be used to lock it in the off position.
