SPC
The SPC050120N7P delivers 50 kA surge capacity at 120 V in a single-phase design, providing robust protection for critical loads against fast transients and reducing the risk of downstream device damage and costly downtime. This directly improves panel reliability and minimizes downtime for machine tools, robotics cells, and automation lines, translating into higher productivity and longer equipment life. Integrated filtering and a Form C relay offer clean power signals and reliable fault indication to the control system, reducing EMI-related disturbances and enabling quick, actionable maintenance responses in automated manufacturing environments. The rugged NEMA 4X enclosure plus external-side mounting ensures installation versatility in wash-down and outdoor settings, while standard 120 V circuits simplify retrofits and OEM panel builds with minimal wiring adjustments. UL 1449 certification and a 10-year warranty deliver compliance confidence and predictable lifecycle costs, supporting budget planning for capital projects across industrial facilities.

FAQs
The SPC050120N7P is designed for external-side mounting and fits standard 120 V control circuits commonly found in industrial panels. When retrofitting, verify clearance, ensure the enclosure is rated for environmental conditions, and plan wiring to connect to the controlled load with minimal disruption. The unit’s dimensions (5.5 in length, 6 in height, 3.19 in width) and weight (2.5 lb) support straightforward integration into most cabinet layouts.
Key specifications include a 50 kA surge rating at 120 V, single-phase configuration, and UL 1449 certification. It provides filtering and a Form C relay for signaling, all housed in a NEMA 4X enclosure. These features deliver reliable transient suppression, reduced EMI, and clear fault indication for downstream protection circuits and PLC inputs.
Yes. The device is housed in a NEMA 4X enclosure, which offers protection against water, dust, and other harsh conditions typical of outdoor or wash-down environments. External-side mounting further supports flexible installation in rugged manufacturing settings without compromising protection performance.
The SPC050120N7P is UL 1449 listed, indicating compliance with recognized electrical safety standards. This certification, combined with the NEMA 4X enclosure, helps satisfy regulatory and industry requirements for critical protection devices in industrial automation and electrical installations.
By limiting transient damage and reducing nuisance trips, the SPC050120N7P lowers downtime, extends the life of drives and control electronics, and decreases maintenance interventions. The device carries a 10-year warranty, providing long-term value and predictable total cost of ownership for OEMs and end users deploying protection across lines and panels.
