FAQs
The SPM120600Y4R is designed for 347/600 V Wye systems and supports a 4W+G setup. Begin by mounting the unit in a NEMA 4 enclosure, connect the four conductors (three hot lines plus ground) to the appropriate terminals, and verify proper grounding. The internal circuit breaker allows isolated testing and quick fault isolation, aiding commissioning and ongoing maintenance.
A 120 kA per phase rating indicates the device can safely absorb high-energy surges on each phase without failing, reducing the risk of downstream equipment damage. This is particularly valuable for facilities with high transient activity from motors, transformers, or lightning events, helping to minimize unplanned downtime.
Yes. The SPM120600Y4R is part of Eaton’s SPD Max family and is designed to integrate with Power Xpert protection architectures, allowing centralized monitoring, coordinated protection, and simplified asset management across multiple panels and sites.
This device is UL 1449-listed and housed in a NEMA 4 enclosure, providing proven safety performance and suitability for harsh environments. These certifications help meet industry electrical codes, reduce inspection risk, and support traceability in regulated facilities.
Routine checks should include visual inspection for enclosure integrity, verification of connection torque, and periodic functional testing of the internal circuit breaker. Many facilities pair the unit with Eaton’s monitoring tools to track surge events, enabling proactive maintenance and justifying the investment through reduced downtime and extended asset life.
