Eaton SPC050240H5P Surge Protection Device - UL 1449
Part Number: SPC050240H5P
Quick Summary
The Eaton SPC050240H5P surge protection device protects electrical systems from transient surges in 240V delta industrial panels. Power disturbances can cause costly downtime, unexpected equipment wear, and expensive maintenance, which this SPD mitigates with rapid response. UL 1449 listed protection and a NEMA 4X enclosure ensure safe operation in challenging environments, while the device supports alarm signaling. By combining robust surge protection with external-side mounting, the SPC050240H5P adds reliability and simplifies installation, enabling faster ROI. Its 50 kA rating addresses high-energy surges common in modern facilities, while the 240V delta configuration suits critical motor loads. With a built-in Alarm and Form C relay, maintenance teams receive immediate status updates, reducing diagnostic time and improving uptime.

FAQs
For external side mounting, verify panel clearance and mounting rail compatibility to fit the device footprint. The SPC050240H5P is designed for external-side installation, simplifying wiring of line, load, and ground conductors. Use proper conduit entries and sealed fittings to preserve the NEMA 4X rating and ensure safe, moisture-resistant operation within harsh environments.
A 50 kA surge rating means the device can absorb high-energy transient events without compromising protection downstream. In 240V delta systems with motors and drives, this translates to tighter voltage clamping during lightning or switching surges, reducing insulation stress, extending component life, and minimizing unexpected downtime in critical production lines.
Yes. The SPC050240H5P utilizes a NEMA 4X enclosure designed for indoor and outdoor installations where dust, moisture, and corrosion could be an issue. This makes it suitable for factory floors, outdoor panels, and exposed electrical rooms, delivering reliable protection without additional enclosures.
The built-in Alarm and Form C relay offer a discrete, switchable signaling path to indicate surge events or fault conditions. This enables remote monitoring, integration with SCADA or BMS systems, and proactive maintenance scheduling, thereby shortening diagnostic time and improving overall equipment uptime.
Deploying the SPC050240H5P can reduce unplanned downtime, extend the life of motors and drives, and simplify compliance with UL 1449 and NEMA 4X standards. While ROI varies by facility, a single robust SPD can lower maintenance costs, minimize warranty open items, and improve production reliability over the equipment’s lifecycle.
