High surge capacity with 160 kA per phase provides robust transient protection, reducing the risk of equipment damage and unplanned downtime; this translates to lower maintenance costs and longer asset life in factory floors and data centers. 230/400 V Wye (4W + G) configuration and an internal terminal block enable straightforward integration with existing panelboards, accelerating commissioning and reducing wiring errors on motor control centers and switchgear assemblies. NEMA 4 enclosure construction supports outdoor and harsh indoor environments, shrinking enclosure upgrades and fencing requirements while maintaining reliable protection in dusty or damp settings. UL 1449 certification confirms compliance with industry safety and performance standards, giving procurement teams confidence to deploy across regulated facilities and critical infrastructure. Compatibility with Eaton’s Power Xpert protection family improves system-wide monitoring and maintenance planning, while the compact yet rugged design helps installers manage space in crowded electrical rooms and control panels.

FAQs
Begin by verifying supply is 230/400 V Wye and ensure the panel or cabinet accepts a four-wire plus ground (4W+G) SPD. Mount the unit within the designated enclosure, connect conductors to the internal terminal block using the factory wiring diagram, and secure all terminations to the recommended torque. If integrating with Power Xpert monitoring, follow Eaton's installation guide to enable status reporting and alarms.
The device provides 160 kA per phase surge current capability and operates at a 230/400 V Wye configuration with 4W+G. It is UL 1449 certified, and designed for reliable protection of critical electrical loads in industrial environments, including switchgear and panelboard installations.
Yes. The unit's NEMA 4 enclosure is engineered for robust dust, water, and weather resistance, making it suitable for outdoors or challenging indoor spaces such as manufacturing floors, machine rooms, and data centers where reliable surge protection is essential.
The SPM160400Y4T carries UL 1449 certification, indicating compliance with safety and performance standards for surge protection devices. It is also specified to be housed in a NEMA 4 enclosure to support use in demanding environments.
Plan periodic visual inspections and confirm UL-listed protection continues to meet performance expectations. The 160 kA per phase protection helps reduce downtime and equipment replacement costs, delivering a favorable return on investment through extended asset life and increased system reliability in production environments.
