FAQs
The SPM120480Y1V is engineered for 277/480 VAC Wye (4W+G) configurations and provides 120 kA per phase surge protection. It integrates as a single-module unit in panels, MCCs, and switchgear, with straightforward wiring and grounding. This compatibility supports reliable protection for motor drives, PLCs, and critical automation assets in industrial facilities.
This model carries UL 1449 and UL 1283 listings and CSA Electrical Notice No. 516 with CSA C22.2 No. 8-M1986. RoHS compliance is included, facilitating regulatory acceptance in North American and international facilities. These certifications help ensure electrical safety, performance under transient events, and alignment with plant safety programs.
Yes, the SPM120480Y1V features an internal circuit breaker within a NEMA 4X enclosure. Maintenance is minimal: conduct periodic visual inspections, verify terminal torque, and document surge history. The standard warranty is 15 years from delivery, with a 20-year option when registered, which reduces long-term maintenance and replacement risk.
By preventing surge-induced damage to controllers, drives, and sensors, downtime is reduced and maintenance costs decline. The 15-year warranty (20 years with registration) lowers lifecycle costs, while improved equipment reliability translates to higher production uptime, lower warranty claims, and a faster payback in facilities with frequent transients or critical automation lines.
Install the unit in a suitable 277/480 VAC Wye panel with a NEMA 4X-rated enclosure and an internal circuit breaker. Ensure correct wiring, conductor sizing, and adherence to NEC guidelines. Verify upstream protection and integrate with the facility’s protection strategy. Outdoor or washdown environments benefit from the enclosure’s robustness, while RoHS compliance supports regulatory requirements.
