Schneider Electric’s SDSA1175 Surgelogic surge protection device is a Type 1 SPD for 120/240 VAC single‑phase systems, designed for indoor or outdoor installation at service entrances or main panels. It delivers up to 36 kA per‑phase surge current, with MCOV 150 V L‑N (300 V L‑L), VPR 700 V, and SCCR 25 kA; the SDSA1175T is the 2‑wire, 120 V version with the same surge specifications. Type 1 SPDs can be used with or without an OCPD, and SDSA1175 is offered in a NEMA 4X enclosure suitable for rugged indoor or outdoor installations to protect downstream equipment from transient surges.
