FAQs
When deploying the SPM250480Y3R in 277/480 V panels, ensure a clean, vibration-free mounting surface and adequate clearance for heat dissipation within a NEMA 4 enclosure. Verify proper bus and conductor sizing for 4W+G configurations, and plan for the internal circuit breaker integration to simplify downstream protection and coordination with upstream devices.
Key specs include a 250 kA per phase surge rating, 277/480 V Wye configuration, single-module construction, and a grounded four-wire (4W+G) system. The device ships with RoHS compliance and is certified under UL 1449, UL 1283, with CSA listing, making it suitable for demanding industrial environments.
Yes. The device is designed with a NEMA 4 enclosure, providing a weather-resistant barrier for outdoor or damp indoor locations. The internal circuit breaker adds an extra layer of protection, enabling safer operation in environments subject to moisture, dust, and temperature variation typical of industrial sites.
This model is RoHS compliant and listed under UL 1449 and UL 1283, with CSA Electrical Notice and CSA C22.2 No. 8-M1986 recognition. These certifications support regulatory compliance, safer installations, and easier qualification for industrial control panels and service entrances.
The SPM250480Y3R reduces unplanned downtime by mitigating transient spikes and extending asset life, which lowers maintenance and replacement costs. Its surge counter simplifies monitoring, while the long warranty—15 years, and 20 years with online registration—improves total cost of ownership and predictability for capital project planning.
