Square D MAM02120ACSC U Molded Case Circuit Breaker

The Square D MAM02120ACSC Series 1 electrical operator is a motorized control accessory that mounts directly to compatible Square D/Merlin Gerin molded‑case breakers to enable remote opening, closing, and tripping of the protected circuit. It uses a 120 V AC control circuit at 50/60 Hz, with an inrush current of 13.6 A and a holding current of 5.5 A during operation. Designed for direct mounting to the breaker frame, the unit measures approximately 200 mm tall, 80 mm wide, and 70 mm deep and weighs about 1.6 kg. This operator is compatible with Square D and Merlin Gerin Masterpact, Compact, and PowerPact series breakers (model dependent) and carries UL Listed, CSA Certified, and IEC 60947-2 compliance. Series 1 designation situates it within the family of electrical operators for remote control of MCCBs. Typical applications include remote operation of main and feeder circuit breakers within automated switchgear, power distribution systems, and emergency power transfer configurations, enabling integration with control systems without replacing the primary protection device. Note that this is not a standalone circuit breaker; it is a motor mechanism accessory that expands the functionality of compatible molded‑case breakers.
