FAQs
Install the unit in a suitable panel or enclosure with adequate clearance for cooling and access to the internal circuit breaker. The device dimensions are 15 in wide, 17.05 in high, and 9.5 in deep, so plan cabinet space accordingly. Use 127/220 V wiring (4W+G) and follow UL 1449 commissioning guidelines to ensure proper coordination with downstream protections.
The SPM250220Y4R delivers 250 kA per phase of surge current protection, mitigating large transient events that can damage drives, PLCs, and sensors. This reduces fault frequency, downtime, and component replacement costs. Proper upstream protection and downstream coordination optimize overall power quality and system reliability.
Yes. The unit is designed to integrate with Eaton's Power Xpert SPD ecosystem, enabling coordinated protection across panels and sites. This compatibility simplifies maintenance, allows centralized configuration, and supports power quality analytics and reporting for a unified protection strategy.
Its UL 1449 listing and NEMA 4 enclosure make it suitable for indoor and outdoor installations, including damp or dusty industrial areas, data centers, and protected machine rooms. The 127/220 V four-wire configuration supports common industrial power distribution setups, improving installation flexibility and safety.
Maintenance is typically minimal. Conduct periodic visual inspections and follow manufacturer testing guidelines to verify status, using the internal circuit breaker as a quick status check. Ensure ongoing UL 1449 compliance through routine audits and consider scheduled functional tests aligned with facility power-quality programs.
