Feature 50 kA surge rating → Business Impact: High-energy surge events are absorbed without propagating to protected circuits, reducing component wear and failure risk. Application: Ideal for panel boards and 3-phase systems in manufacturing lines with high inrush loads. Feature 240V Delta compatibility → Business Impact: Aligns with common industrial feeders, simplifying integration and reducing retrofit costs. Application: Directly supports 3-phase equipment like motors and VFDs in delta-configured networks. Feature NEMA 4X enclosure → Business Impact: Enables operation in wash-down, dusty, and outdoor environments without enclosure compromise. Application: Suitable for food & beverage, pharmaceutical, and outdoor rugged installations. Feature Form C relay → Business Impact: Enables remote signaling and fault alerts to PLCs or HMI without additional hardware. Application: Standalone or integrated protection where status monitoring is required. Feature External side mounting → Business Impact: Eases installation and future maintenance with straightforward access and serviceability. Application: Convenient for retrofit projects and crowded electrical spaces. Feature 10-year warranty → Business Impact: Reduces total cost of ownership and replacement cycles, improving lifecycle economics. Application: Long-term asset protection for critical SPS and control panels.

FAQs
To install, power down the panel, mount the unit on the external side using the provided hardware, and connect the lines and load per the wiring diagram. Ensure the 240V delta supply matches the device rating, secure the enclosure to prevent moisture ingress, and wire the Form C relay to your control system for status signaling. Verify tight connections and test with a controlled surge to confirm protection functionality.
Key specs include a 50 kA surge rating, 240V Delta voltage rating, NEMA 4X enclosure, external side mounting, Form C relay, 5.5 in depth, 6 in height, 3.19 in width, and a weight of 2.5 lb. It is UL 1449 listed and backed by a 10-year warranty, with a SPC series designation for compatibility within Eaton protection solutions.
Yes. The 50 kA surge capacity and 240V Delta rating make the SPC050240D4P well-suited for motor drives and VFD-equipped panels. Its external-side mounting simplifies retrofits in existing MCCs, and the Form C relay allows remote monitoring to detect protection events, enabling proactive maintenance and reduced unplanned downtime.
The SPC050240D4P carries UL 1449 certification for surge protection performance. It also features a NEMA 4X enclosure, providing robust environmental protection against dust, water, and corrosion in harsh industrial settings. This combination supports compliance with common industrial protection standards and warranty-backed reliability.
With a 10-year warranty and a high 50 kA protection rating, maintenance requirements are minimal beyond periodic inspection. The device reduces downtime costs by limiting surge-related equipment damage and extends asset life, delivering a favorable return on investment through improved uptime and lower replacement frequency for protected circuits.
