200 kA per phase surge rating delivers robust transient protection for each feeder or branch circuit. This translates into fewer nuisance trips, less insulation wear, and extended life for critical equipment like motor starters, drives, and control electronics. In practice it enables safer retrofits on existing panels and supports uptime in high-energy environments such as stamping, machining, and material handling lines. The 127/220 V Wye (4W + G) configuration simplifies integration into standard industrial power distribution, reducing wiring complexity and the chance of misconnection. Business impact includes faster install times and fewer wiring errors, lowering commissioning costs and improving safety in factories, machine rooms, and data centers. The NEMA 4 enclosure with an internal circuit breaker provides reliable protection against dust and wash-down exposure while offering a convenient disconnect during routine maintenance. This reduces field service time and protects personnel. UL 1449 listing confirms electrical safety and performance under surge conditions, helping meet stringent procurement specs and insurer expectations. Power Xpert SPD compatibility enables centralized monitoring and faster diagnostics, enhancing overall system reliability. With a compact footprint of 9.5 in depth, 17.05 in height, and 15 in width, and a 52 lb weight, it fits standard installations while maintaining service access for routine checks.

FAQs
Install the SPM200220Y4R in a suitable electrical panel door or cabinet that supports a 127/220 V Wye configuration. Ensure the device is mounted per Eaton’s installation instructions, with the internal circuit breaker accessible and the 4W + G wiring correctly connected to phase and ground. Verify proper strain relief on cables and confirm voltage rating matches system design prior to energizing the circuit.
A 200 kA per phase rating indicates the SPD MAX unit can withstand and redirect high-energy transient events on each phase without failing. This reduces the likelihood of downstream equipment damage, lowers maintenance interruptions, and supports continuity for critical loads such as motors, drives, and PLCs in demanding manufacturing environments.
Yes, the SPM200220Y4R is designed for 127/220 V Wye (4W + G) systems. Wire the four conductors according to the wiring diagram, connecting the three phase lines and the neutral/ground as specified. The internal circuit breaker should be placed for convenient isolation during maintenance, and proper clearance around the enclosure should be maintained for heat dissipation.
The device is UL 1449 listed, confirming electrical safety and performance under surge conditions. It ships in a NEMA 4 enclosure with an internal circuit breaker, providing protection against dust, water, and wash-down environments, suitable for indoor and outdoor installations in challenging facilities.
By preventing surge-related damage to critical equipment, the SPM200220Y4R lowers unplanned downtime, extends asset life, and reduces maintenance costs. Its compatibility with standard 127/220 V systems and centralized monitoring via Power Xpert SPD tools improves diagnostics and uptime, delivering tangible return on investment in manufacturing plants and data centers.
