Schneider Electric MA1IMA12 Transient Voltage Surge Suppressor

Schneider Electric's Square D Surgelogic MA1IMA12 Surge Protection Module delivers 120 kA peak surge current protection for 120/240 VAC, single-phase, three-wire systems. As part of the Surgelogic MA family, this module is designed to be installed in panelboards and compatible switchgear to clamp transient overvoltages from lightning or switching events and protect downstream equipment. The MA1IMA12 designation corresponds to a 120/240 V, 1-phase, 3-wire configuration and is listed with CSA (T2) certification, reflecting its compliance with applicable safety and performance standards. Typical applications include safeguarding motor drives, controls, sensors, relays, and other sensitive electronics in commercial and light-industrial environments where durable surge protection is required. With a 120 kA peak surge current rating, it provides energy absorption suited to robust electrical systems, and it integrates with Schneider Electric’s Surgelogic protection schemes to maintain coordinated protection across multiple devices and circuits.
