The SPC050120N2P provides a 50 kA surge rating for 120 V single-phase circuits, delivering robust protection against high-energy transients. By diverting these spikes away from critical electronics, it minimizes nuisance trips and costly downtime. This makes it particularly well-suited for PLCs, motor drives, and HMI panels in control cabinets. The device incorporates UL1283 5th Edition filtering to suppress EMI and noise on power lines, improving control reliability and reducing electromagnetic interference with nearby equipment. It is designed with a rugged NEMA 4X enclosure that protects against dust, water, and corrosive environments, making it ideal for outdoor installations and wash-down facilities. External side mounting simplifies installation and retrofit, reducing wiring complexity and enabling quick replacements in existing panels or distribution boards. With a 10-year warranty and UL 1449 certification, it lowers total cost of ownership while supporting compliance in industrial environments. As part of the SPC series, it offers consistent protection across power feeds and control circuits, ensuring compatibility and scalability in expanding automation systems.
