Eaton SPC150277N3P Surge Protection Device - UL 1449

With a 150 kAIC interrupt rating, the SPC150277N3P delivers robust surge containment, reducing the risk of arc faults and downstream equipment burnout. This translates to measurable business impact: fewer unplanned outages, longer equipment life, and lower maintenance costs in critical lines such as motors and drives. It’s ideal for 277 V single-phase systems commonly found in industrial control panels and utility rooms. 277 V single-phase compatibility ensures seamless integration with existing electrical architectures. The device is designed for external side mounting, simplifying retrofits and minimizing wiring complexity while preserving panel space. In practice, this means faster installations and reduced downtime during upgrades. Durable protection is provided by a NEMA 4X enclosure, enabling operation in wet, dusty, or outdoor environments. Pairing enclosure robustness with UL 1449 certification gives you compliance confidence and long service life, even in rugged environments. The audible alarm provides immediate status feedback, enabling quick fault isolation without pulling panels apart. Auditory signaling supports proactive maintenance and reduces response times by notifying personnel of surge events. This aligns with lean maintenance strategies and helps protect critical systems like conveyors, presses, and HVAC controls from spikes. The compact footprint and external side mounting aid in retrofits in crowded electrical rooms. Warranty support spans 10 years, underscoring Eaton’s confidence in long-term protection. The combination of warranty, reliability, and proven protection reduces total cost of ownership while aligning with standards like UL 1449.
