FAQs
SPM300220Y4T is designed for panel boards, control cabinets, and switchgear in industrial settings. The 127/220V Wye (4W+G) configuration supports flexible distribution schemes, enabling deployment in mixed-voltage facilities without needing multiple protection devices. The internal terminal block simplifies wiring and reduces field wiring errors during installation.
A rating of 300 kA per phase indicates the SPD can safely shunt very high-energy surges away from connected equipment, protecting sensitive loads like drives, PLCs, and relays. This high-energy capability reduces the likelihood of equipment damage during severe transient events and supports longer equipment life and fewer unplanned outages.
Yes. The device uses a NEMA 4 enclosure, providing protection against dust, water, and wash-down environments. This makes it appropriate for outdoor panels, damp factory floors, and other demanding settings where reliable protection and rugged construction are essential.
The unit carries UL 1449 certification, ensuring compliance with established surge protection standards, and ships in a rugged NEMA 4 enclosure. These certifications help meet procurement requirements, support regulatory compliance for electrical assemblies, and reduce project risk during safety reviews and audits.
By limiting surge-induced failures, this SPD minimizes downtime and maintenance costs while extending the life of critical equipment like motors and drives. The integration with Eaton's protection ecosystem also simplifies monitoring and servicing, delivering faster commissioning, predictable operation, and a favorable total cost of ownership over the equipment’s lifespan.
