Surgelogic SDSA1175 surge protective devices are designed and listed for indoor or outdoor installation and surge suppression for single-phase three-wire 120/240 Vac or two-wire 120 Vac 60 Hz electrical services. This product is ideal for panel builders as well as manufacturers and integrators of instrumentation cabinets for industrial and commercial applications for single-phase power systems.
Surgelogic SDSA three-phase surge protective devices are designed and listed for indoor or outdoor installation and surge suppression for three-phase electrical services up to 600 Vac. The SDSA three-phase series is used extensively in service entrance panels to provide an efficient and economical means of surge suppression and also ideal for point of use applications for that added level of protection.
Surgelogic SPDE surge protective devices add neutral to ground (N-G) protection and optional dry contacts (DC) and audible alarm (AA). The SPDE can also be mounted on a DIN Rail with the included mounting bracket.
US and Canadian UL Listed as Type 1 SPD to the UL 1449 standard. Complies with requirements of NEC Article 285 (2017), CSA C233.1–87, and CSA C22.2 No. 8–M1986 as appropriate.
