FAQs
SPC120240H5P is designed for external side mounting with a footprint that fits typical industrial enclosures. It protects 240V delta systems, supports a 120 kAIC interrupt rating, and carries UL 1449 certification. With a 4 lb weight and a rugged NEMA 4X enclosure, it simplifies retrofits in existing panels without extensive rewiring or enclosure modification.
The 120 kAIC rating indicates the maximum instantaneous fault current the device can interrupt without damage. This translates to stronger protection for downstream equipment and higher reliability during severe transient events, reducing the risk of cascading failures in manufacturing lines and critical control circuits.
Yes. The unit uses a NEMA 4X enclosure, designed for moisture, dust, and corrosion resistance, enabling outdoor installations or harsh indoor environments. This makes it suitable for exterior panels, outdoor substations, or rugged plant floors where protection from the elements is essential.
The integrated Alarm and Form C relay provide ready-made signaling for condition monitoring and control system integration. This enables early fault detection, rapid operator notification, and seamless connection to SCADA or BMS workflows, reducing response times and supporting proactive maintenance programs.
Eaton backs the SPC120240H5P with a 10-year warranty, reflecting confidence in long-term reliability. This, combined with UL 1449 certification and robust 120 kAIC protection, supports lower lifecycle costs, predictable budgeting, and streamlined compliance documentation for asset-heavy facilities.
