FAQs
Yes, the SPM120400Y4R supports 230/400 V Wye (4W+G) configurations. It is designed for installation in standard electrical enclosures with a NEMA 4 rating, providing weather and dust resistance. Mounting in machine control cabinets can be accomplished using standard panel mounting methods, with wiring to the protected power bus and ground as per the Eaton installation guide.
120 kA per phase means the device can absorb high-energy transient surges on each phase without reaching its protection limit. This translates to better protection for drives, PLCs, and sensitive electronics, reducing the likelihood of insulation and component damage during lightning events or switching transients in industrial environments.
Yes. The SPM120400Y4R is well-suited for motor control centers and machine control panels where high-energy transients are common. Its UL 1449 certification, NEMA 4 enclosure, and internal circuit breaker support reliable protection for automation assets, minimizing downtime and maintenance costs on high-demand production lines.
The SPD carries UL 1449 certification and a NEMA 4 enclosure rating. UL 1449 confirms surge protection performance and safety compliance, while NEMA 4 ensures suitability for indoor/outdoor, harsh environments. This combination supports regulatory compliance, reduces risk during audits, and promotes dependable protection in industrial facilities.
With an internal circuit breaker and robust enclosure, maintenance is streamlined and field wiring is simplified, which lowers service time and labor costs. The reliability of 120 kA per phase protection reduces unexpected equipment failures, extending asset life and delivering a favorable return on investment through minimized downtime and replacement expenses.
