1P surge protection for 120 V systems delivers fast response to transients, reducing unplanned downtime in critical control panels and automation loops. The business impact is clear: higher line reliability, fewer process interruptions, and improved asset lifespan for PLCs and drives in manufacturing environments. The application is ideal for industrial panels, equipment rooms, and outdoor enclosures where compact protection is needed without sacrificing performance. 50 kAIC interrupt rating combined with a 20 kA Imax discharge ensures robust surge handling for demanding loads. The result is minimized equipment damage during high-energy surge events, enabling safer startup sequences for motors and drives and lowering maintenance costs over the system life. This is well-suited for medium and large automation installations requiring durable protection

FAQs
The SPC050120N1P is designed for external side mounting, enabling straightforward installation on or near the protective panel. This mounting approach simplifies integration with existing enclosures and reduces the footprint required in space-constrained control cabinets, making retrofits or upgrades quick and non-disruptive.
Key specs include 120 V nominal operation, 50/60 Hz, 50 kAIC interrupt rating, and a maximum discharge current of 20 kA (8x20µs). It also features a nominal system voltage of 120 V and an operating voltage of 120 V. These figures guide protection sizing for PLCs, drives, and related load equipment in typical industrial environments.
Yes. It comes with a NEMA 4X enclosure designed for harsh environments and reliable outdoor or wash-down applications. The device operates over a wide temperature range from -40 °C to 65 °C, ensuring protection in extreme facility conditions without performance degradation.
This model is UL 1449 certified, which supports compliance with established electrical safety standards. In addition, its rugged enclosure and 10-year warranty further reinforce reliability expectations for ongoing maintenance programs in industrial facilities.
By mitigating surge-induced downtime and protecting critical automation assets such as PLCs and drives, the SPC050120N1P lowers maintenance costs and extend asset life. Its durable enclosure and easy installation reduce commissioning time, while UL certification and warranty help justify preventive protection investments as part of a broader reliability program.
