Feature → 100 kAIC interrupt rating provides robust surge handling, reducing downstream damage and extending the life of connected equipment. Business Impact → Fewer component failures mean lower replacement costs and less unplanned downtime in manufacturing lines. Application → Ideal for electrical panels and automation cabinets where high transient energy can originate from motors or switching operations. Feature → Filtering & Form C relay outputs help suppress EMI and provide reliable signaling for alarms or interlocks. Business Impact → Improved control stability and clearer fault indication translate to faster diagnostics and safer shutdown sequences. Application → Suitable for PLC interfaces and control loops that depend on clean signals. Feature → 120 V single-phase configuration with a NEMA 4X enclosure delivers dependable protection in wet, dusty, or outdoor environments. Business Impact → Enables outdoor or harsh-location installations without enclosure upgrades, reducing installation time and cost. Application → Field installations adjacent to machinery or in protected outdoor panels. Feature → External side mounting and a compact 5.5 in depth by 3.19 in width profile simplify panel integration. Business Impact → Easier retrofits and faster installations with minimal panel modification. Application → OEM panel builds and retrofit projects where space is constrained. Insight → The SPC series aligns with common industry practices for surge protection in 120 V control panels and automation cabinets, offering a practical balance of protection, signaling, and installation efficiency while supporting long-term maintenance and warranty commitments.

FAQs
The SPC100120N7P is designed for 120 V single‑phase systems and installs on the external side of panels. Its compact footprint (5.5 in depth, 3.19 in width) allows retrofit into existing control enclosures without major rework. For OEMs and integrators, this compatibility minimizes downtime and simplifies specification in new builds.
Key specs include 120 V voltage rating, single‑phase configuration, and a 100 kAIC interrupt rating, which ensures high-energy surge events are absorbed without downstream damage. The device also features UL 1449 listing, a NEMA 4X enclosure, and Form C relay outputs for signaling and control feedback.
Yes. The SPC100120N7P is housed in a NEMA 4X enclosure, providing moisture and dust resistance for challenging environments. This makes it suitable for outdoor panels, damp indoor spaces, or locations with washdown exposure, reducing the need for additional protective housings.
Filtering reduces EMI and transients that can affect PLC inputs and drives, improving signal integrity. The Form C relay outputs provide reliable, normally open/closed signaling suitable for alarms, interlocks, or remote sensing. This combination supports safer, more predictable control logic and faster fault diagnosis.
Plan for external side mounting on 120 V panels to minimize enclosure modification. Verify mounting clearances around the 5.5 in by 3.19 in footprint and ensure proper wiring to achieve the 100 kAIC protection. With UL 1449 listing and a 10‑year warranty, this SPD supports long-term reliability and reduced maintenance costs.
