FAQs
Install the SPC150240N4P on the exterior side of the panel for easy access and wiring. Ensure the enclosure is sealed per NEMA 4X requirements, connect line and load conductors to the appropriate terminals, verify proper grounding, and confirm the Form C relay wiring aligns with your PLC or annunciation circuit. Refer to the Eaton specification sheet for exact terminal layout and torque values.
The 150 kAIC interrupt rating means the device can safely interrupt up to 150 kiloamperes of fault current energy in a surge event. This rating ensures resilience against high-energy transients typical in industrial environments, reducing the likelihood of downstream component damage and preserving uptime for critical machinery and controls.
Yes. The SPC150240N4P is UL 1449 listed and housed in a NEMA 4X enclosure, which provides weather-resistant protection for indoor and outdoor installations in damp or wash-down environments. This combination supports reliable performance in challenging plant conditions while meeting safety and compliance expectations.
The SPC150240N4P carries a 10-year warranty, reflecting Eaton’s confidence in long-term reliability. Maintenance is typically minimal; perform periodic visual inspections for enclosure integrity, verify terminal tightness during preventive maintenance, and test the relay contacts as part of routine control-system health checks to ensure continued protection of connected equipment.
The Form C relay provides a configurable switching interface for signaling or interlocking with PLCs, annunciators, or alarm circuits. This simplifies fault indication, enables remote control of protection logic, and enhances overall automation performance in 240V panel applications, including machine controls and building automation systems.
