FAQs
Installation should place the SPC150480D4P on the external side of the panel in a NEMA 4X-rated enclosure where exposure to moisture or washdowns is possible. Ensure proper clearance for heat dissipation, connect to the 480V Delta supply, and utilize the Form C relay for control signaling. Validate panel access and follow local electrical codes during retrofit or new-build projects.
A 150 kAIC rating indicates the device can safely interrupt very large surge currents without failing, offering higher resilience against industrial transients. This reduces the likelihood of downstream equipment damage and downtime, making it suitable for demanding environments with frequent or intense surges such as heavy manufacturing lines and motor drives.
Yes. The SPC150480D4P carries UL 1449 certification and uses a NEMA 4X enclosure, which is designed for outdoor and washdown environments. This combination ensures regulatory compliance and reliable protection in harsh conditions commonly found in outdoor switchgear, service entrances, and external panels.
Regular inspections are recommended, focusing on visual signs of wear, corrosion, or damage to the enclosure and connections. Since the device includes a Form C relay, verify signaling is functioning, and test the control circuit periodically. Consider replacement after a surge event or if the unit shows any degradation in performance to maintain protection integrity.
Yes. With a 480V Delta rating, 150 kAIC interrupt capacity, and Form C relay signaling, the SPC150480D4P is well-suited for protecting downstream drives, panels, and control electronics in high-uptime facilities. Its external mounting and robust enclosure simplify integration into existing architectures, helping maintain uptime and extend equipment life.
