The Merlin Gerin MT630 motor operator (part number 996961) is a compact 110–130 VAC control mechanism that actuates NS-series molded‑case circuit breakers with up to 500 VA of actuation power in 50/60 Hz systems. It is compatible with NS, NSJ, NJNF, NJNL, NJHF, and NJHL frames (630 A class) and is designed for distribution panels that require motorized opening and closing of the breaker. Typically paired with Merlin Gerin NS equipment, this MT630 motor mechanism enables reliable remote or automated operation of the breaker in industrial control applications.
