FAQs
The SPM160480Y1R should be mounted in a compatible enclosure with a labeled 277/480 V Wye configuration. Wire the line and load conductors to the protected module per the Eaton installation sheet, ensure the internal circuit breaker remains in the default position, and verify the unit is clearly grounded. Verify RoHS compliance and enclosure integrity before energizing to prevent nuisance trips and ensure long-term protection.
The device carries UL 1283 and UL 1449 listings along with CSA Electrical Notices and CSA standards, signaling compliance with safety and performance benchmarks for surge protection devices. These certifications help meet industry regulatory requirements, support system-level approvals, and provide assurance to engineering and procurement teams during design reviews and audits.
Yes. The unit comes in a NEMA 4 enclosure, which is designed for indoor/outdoor use and provides protection against dust, rain, and washdown. This makes it suitable for protected outdoor equipment rooms and harsher manufacturing environments where reliable surge protection is required without enclosure degradation.
Key specs include a 160 kA per phase surge rating and a 277/480 V Wye (4W+G) configuration. The device is a single module with an internal circuit breaker and a 9.3 in depth, 17.5 in height, and 14.91 in width footprint. These details inform space planning, wiring schedules, and coordination with overcurrent protection in the panel.
By clamping transients more effectively, the SPM160480Y1R reduces insulation stress on downstream equipment, lowers repair/replacement frequency, and minimizes unplanned downtime. The long warranty and RoHS/UL/CSA certifications support asset reliability and predictable maintenance budgeting, delivering a favorable return on investment over the equipment lifecycle.
