SPC
The SPC150240S4P is rated at 150 kAIC, enabling it to clamp large swells without nuisance tripping, which reduces downstream equipment damage in motor drives and PLC power rails. This high interrupt rating translates to fewer outages and lower maintenance costs in distribution panels and MCCs. The unit features a split‑phase 120/240 V supply with a rugged NEMA 4X enclosure and external side mounting that supports indoor and outdoor installations and simplifies retrofit in existing housings. A Form C relay provides dry-contact signaling for alarms or interlocks, improving remote monitoring and integration with BMS or PLC logic. UL 1449 certification and a 10‑year warranty assure compliance and long‑term reliability in industrial automation environments. Measured dimensions and weight (7.5 in depth, 8.5 in height, 3.19 in width, 4 lb) enable straightforward fit in standard panels and enclosures.
