Square D SSP02EMA12D is a Type 1 surge protective device (SPD) from the QO family, designed to safeguard 3-phase, 4-wire electrical systems against transient overvoltages. It operates at a voltage rating of 208Y/120V AC with a 120kA surge current capacity and a 150A line rated current, while supporting a maximum continuous operating voltage of 150V. The unit features a surface-mount NEMA 1 enclosure measuring 19.5 in (495 mm) by 9.9 in (251 mm) by 5.3 in (135 mm) and weighing 25.168 lb, with lug terminals for AWG 10 to AWG 3/0 copper wire. It complies with CSA C22.2 No 8, UL 1449 ed. 4, and UL 1283 ed. 5 standards, and includes a switch-disconnector, surge counter, alarm enable/disable switch, dry contacts for remote signaling, and LED status indicators for local fault indication. This SPD is suited for industrial and commercial applications requiring robust surge protection in main service panels or distribution equipment.
