The MMTC 110V Reversing Contactor is an electromechanical motor-control device used to change the rotation of an AC motor for open/close functions in overhead door operators, rolling grilles, gate operators, and light industrial machinery. Energized by a 110 VAC control signal, it toggles between forward and reverse to provide precise directional control from wall stations, key switches, or access control receivers. Frequently selected as a replacement part in existing panels that specify a 110V coil reversing contactor, it supports residential and commercial applications where dependable, straightforward forward/reverse operation is needed.
For correct application, match the 110 VAC coil to the control voltage and confirm that the contact ratings align with the motor’s voltage, phase, and full-load current as published on the product label or datasheet. Installation should be performed by a qualified technician in accordance with local electrical codes, with appropriate overload protection and interlocking to prevent simultaneous forward and reverse engagement. This MMTC reversing contactor integrates with common open/stop/close circuits and logic boards that provide a 110V output, offering a reliable replacement for worn or sticking contactors in commercial door and gate operator systems.
