MA4IMA161 | Square D | Power Monitoring & Protection

Surge logic EMA replacement modules surge protective devices are apart of modular brick parallel device. The EBA device has multi-stage suppression circuits consisting of field-proven, fast-acting metal oxide varistors (MOVs). These systems provide suppression, enhanced EFI/RFI filtering for all critical modes inside electrical equipment, and shorter lead lengths with superior SPD performance. This surge protection device is 3 phase, 4-wire + ground, 480 Y/277 V, 160 kA surge current per phase, and short circuit current rating of 200 kA. They provide better performance with a diagnostic interface with push to test switches, red and green status LEDs, module status LEDs per mode, dry contacts, audible alarm with disable switch, and a surge counter. The device is engineered to UL 489 11th Edition, type 2 SPD and complies with UL 96 A 12th Edition Master Label for Lightning Protection Systems.
