FAQs
The SPM100400Y4T is rated for 230/400 V in a Wye (4W + G) configuration. It supports three-phase power with a dedicated grounding conductor, making it suitable for standard industrial power distributions and panel installations. This configuration aligns with common customer IEC/IEEE power designs and simplifies integration with existing electrical systems.
Yes, the SPM100400Y4T carries UL 1449 listing for surge protection device safety. It is housed in a NEMA 4 enclosure, providing protection against rain, wind-driven dust, and splash zones, which makes it suitable for both indoor and outdoor installations adjacent to equipment rooms, panels, or outdoor electrical facilities.
This surge protector is ideal for protecting critical loads such as motors, drives, PLCs, and control panels in manufacturing lines, processing plants, and data centers. Its high surge rating, rugged enclosure, and Power Xpert compatibility help reduce downtime, extend asset life, and simplify maintenance in budgets-conscious operations.
A 100 kA per phase rating provides robust transients protection, minimizing downstream damage to expensive drives and control systems. The result is lower repair and replacement costs, fewer unplanned outages, and faster return-to-service times, delivering measurable uptime improvements and a lower total cost of ownership over the equipment’s life cycle.
Plan for a 52 lb unit within a large 9.5 in D x 17.05 in H x 15 in W footprint, ensuring adequate clearance for wiring and servicing. The internal terminal block simplifies wiring, while the 230/400 V Wye configuration supports straightforward integration with existing panels. Verify NEMA 4 suitability for the installation site and ensure UL 1449 compliance for procurement alignment.
