Square D SSP01EMA12S is a Type 1 surge protective device (SPD) designed for primary protection of single-phase electrical systems against transient overvoltages. It operates at 120/240VAC with a 120kA surge current rating and a 20kA nominal discharge current, featuring a 200kA short-circuit current rating (SCCR) for robust fault handling. The unit is housed in a NEMA 4X stainless steel enclosure measuring 22.7 in (575.8 mm) x 11.7 in (297.2 mm) x 9.4 in (238.8 mm) and weighing 32.201 lb, with surface mounting and copper wire connections from AWG 10 to AWG 2. It complies with CSA C22.2 No 8, UL 1449:ed. 4, and UL 1283:ed. 5 standards, holding UL and CSA certifications for safety and performance. This SPD is suited for service entrance and point-of-use applications in harsh industrial environments, providing audible, visual, and remote signaling for status monitoring.
