FAQs
The SPC120120N4P uses external side mounting to integrate with standard electrical cabinets. Begin by locating a suitable, well-ventilated section of the panel, ensuring compatibility with 120 V single-phase circuits. Mount the unit using the provided hardware, connect line and load terminals per Eaton's wiring diagram, and verify the Form C relay is wired for your monitoring system. After installation, test with a temporary power sequence to confirm proper surge clamping and remote signaling operation.
This device provides a 120 kAIC interrupt rating, designed to absorb and divert high-energy transients typical in industrial environments. It operates at 120 V single-phase, delivering reliable surge protection for downstream equipment such as PLCs, drives, and control electronics. The rating combines with the UL 1449 certification to meet common safety and performance requirements in commercial and industrial applications.
Yes. The unit features an NEMA 4X enclosure, which offers sealing against water and dust ingress, enabling reliable performance in outdoor, damp, or wash-down locations. This makes it well-suited for factory floors, outdoor panels, and areas with higher exposure to contaminants, while maintaining robust surge protection for critical systems.
Key certifications include UL 1449 listing, which verifies surge protection performance and safety compliance. The enclosure is rated NEMA 4X for environmental protection, providing confidence for installations in challenging industrial settings. These certifications support regulatory compliance and aid in passing audits for safety and reliability.
The SPC120120N4P is designed for long-term reliability with a 10-year warranty, reducing total cost of ownership. Minimal routine maintenance is typically required beyond periodic electrical testing during commissioning and scheduled inspections. Its durable construction and proven protection translate to fewer unplanned outages and lower replacement costs over the equipment’s life cycle.
