FAQs
The SPM250480D1R is designed for 480 Delta (3W+G) systems and features a NEMA 4 enclosure with an internal circuit breaker, enabling outdoor and harsh indoor installations. Ensure proper panel clearance, space for 14.91 in width, and alignment with upstream protection to support coordinated overcurrent protection and fault isolation.
The device provides up to 250 kA per phase protection, effectively clamping transient voltages and diverting surge energy away from motors, drives, and controllers. This rating supports protection for high-energy transformers and large loads typical in manufacturing lines, reducing insulation stress and extending device life.
Yes. The enclosure is rated NEMA 4, offering protection against dust, water ingress, and corrosion in challenging environments. This makes it suitable for outdoor installations and damp indoor spaces where reliability and ease of maintenance are critical.
The unit carries RoHS compliance and certifications including CSA Electrical Notice No. 516, CSA Std. C22.2 No. 8-M1986, UL 1283, and UL 1449. These certifications support compliance in regulated industries and simplify procurement for projects requiring recognized safety and performance marks.
Eaton offers a 15-year warranty from delivery, extended to 20 years upon registration on the Eaton SPD site. This extended coverage improves total cost of ownership by reducing maintenance and replacement costs, making the SPM250480D1R a compelling choice for mission-critical protection in busy facilities.
