MA4IMA12

The MA4IMA12 surge protection module, part of Schneider Electric's Surgelogic series, is engineered for efficient transient voltage suppression in electrical systems. This module operates on an alternating current with a rated voltage of 480 V. It is structured for three-phase installation and utilizes a 4-wire configuration. The maximum continuous operating voltage (MCOV) is 320 V, ensuring that equipment remains protected during surges.

This device has a surge capacity of 120 kA, providing robust protection against sudden voltage spikes. The nominal discharge current is rated at 20 kA, allowing for effective dissipation of surges while minimizing risk to downstream equipment. Local status indicators in the form of LEDs provide immediate feedback on system operation, enhancing usability.

The surge protection module is mounted on a panel, facilitating integration into various installations. Its dimensions measure 6.3 inches in height, 3.3 inches in width, and 2.7 inches in depth, making it compact yet efficient. The enclosure complies with NEMA 2 standards, offering general protection against dust and indirect moisture, making it suitable for a variety of environments. The short-circuit current rating (SCCR) of 200 kA ensures that the module can handle significant fault conditions, providing confidence in its protective capabilities.
