Surge current
100 kA per phase
High surge current rating of 100 kA per phase provides robust protection against transient spikes. This directly reduces the risk of equipment damage and unplanned downtime in demanding industrial environments. For motor control centers, SPD100220Y4J delivers reliable protection that keeps critical drives and controls online. Voltage rating of 127/220 V Wye (4W+G) enables direct integration with common MCC bus configurations. This compatibility accelerates installation, reduces wiring errors, and shortens commissioning time. In practice, technicians install with confidence, knowing the device aligns with standard 4-wire + ground systems. UL 1449 certification provides verified surge suppression performance and industry compliance. This reduces risk during audits and supports end-user acceptance in regulated settings. The rating also simplifies supplier qualification and helps maintain consistent protection levels across multiple panels. Power Xpert SPD compatibility enables scalable protection with a common protection philosophy. This fosters easier maintenance, standardized parts, and streamlined spare-part inventories across an entire facility. Physical form factor and weight support straightforward installation within crowded MCC enclosures. The compact 3.48 in depth, 7.47 in width, and 12.05 in height fit typical rack layouts, while a 6.8 lb weight simplifies carriage and mounting. Operational efficiency and ROI: The robust surge protection reduces unplanned downtime and extends equipment life, which translates to lower replacement frequencies and improved asset utilization. In practice, engineering teams report faster MCC retrofits and fewer field modifications due to standard 127/220 V Wye compatibility. With Power Xpert SPD integration, you can implement multi-stage protection across several panels, achieving consistent protection and straightforward spare-part management. Installation and maintenance considerations: The device’s accessible terminals and modular design simplify commissioning and future upgrades. With UL 1449 compliance, technicians rely on proven performance and predictable behavior under surge events, reducing diagnostic time during faults. In addition, the Power Xpert ecosystem supports centralized monitoring and coordinated protection strategies across the facility.
