The 50 kA surge rating is a core feature that directly translates to lower risk of damaging transients, reducing unexpected downtime and extending the life of downstream equipment in 240V delta circuits. This protection enables faster recovery, minimizes repair costs, and supports safer, more resilient production lines. The NEMA 4X enclosure is another critical benefit, providing weatherproof and washdown-ready protection that suits both indoor and harsh outdoor applications, reducing enclosure-related failures and facilitating installation in outdoor panels or damp environments. The Form C relay is designed for straightforward signaling and interlock integration with existing controls, enabling proactive alarm and remote control actions to improve plant visibility and response time. With external side mounting, technicians gain flexible access during installation or replacements, minimizing panel disruption and downtime during maintenance. These features align with common industrial priorities—compliance with UL 1449, extended warranty coverage, and reliable protection for critical loads—while enabling smoother integration with SPC series devices in new or retrofit projects. In practice, engineers can design more robust surge protection into machine tools, conveyors, and automation panels, achieving measurable uptime improvements and safer operations across facilities.

FAQs
The SPC050240H4P is designed for external side mounting in protected enclosures, with a NEMA 4X rating suitable for indoor and outdoor use. Ensure panel cutout compatibility and proper clearance for the 5.5 in depth, 6 in height, and 3.19 in width footprint. The device uses a 240V delta (4W+G) supply and requires standard surge protection wiring practice per UL guidelines. Mounting should maintain accessible signaling paths for the Form C relay and allow for easy replacement when service is needed, minimizing downtime.
This unit provides a 50 kA surge rating, suitable for absorbing transient overvoltages common in industrial environments. It supports 240V delta systems (4W+G) and includes a Form C relay for signaling. The enclosure and construction are UL 1449 listed, ensuring compliance with recognized surge suppression standards and safe operation within industrial control panels.
Yes. The model is specified for 240V delta (4W+G) configurations, including High Leg Delta environments. Its rugged NEMA 4X enclosure and 50 kA surge capability make it well-suited for protecting motors, drives, and control panels in production lines where transient events and outdoor exposure are concerns.
The SPC050240H4P is UL 1449 listed, providing essential protection against transient overvoltages. The NEMA 4X enclosure offers environmental protection against dust, water, and corrosion, supporting compliance in challenging plant environments. A 10-year warranty further reinforces reliability and long-term cost of ownership, useful in budgeting and maintenance planning.
The Form C relay provides a configurable signaling path to alarms or interlocks, enabling proactive maintenance and rapid fault isolation. This reduces unplanned downtime and simplifies integration with existing control architectures, improving response times during transients. Combined with the 10-year warranty and UL 1449 listing, it translates to lower total cost of ownership and greater system uptime.
