FAQs
SPD100220Y4B is designed for use with Power Xpert SPD equipped switchgear that includes a remote display. It fits standard 127/220 V Wye (4W+G) systems and accommodates a compact footprint (3.48 in D, 7.47 in W, 12.05 in H). Ensure panel space, grounding provisions, and wiring lugs meet local electrical codes for safe, reliable installation.
The 100 kA per phase rating indicates the device can safely absorb a high-energy transient per phase without compromising performance. This limits voltage spikes reaching downstream equipment, reducing insulation stress, preventing misoperation of relays, and lowering the likelihood of unplanned downtime in heavy-duty switchgear environments.
Yes, SPD100220Y4B is well-suited for data centers, manufacturing lines, and other mission-critical facilities that depend on continuous power. The 127/220 V Wye configuration aligns with common industrial power systems, and its 4W+G setup supports reliable grounding. UL 1449 certification further reinforces suitability for compliant, high-reliability applications.
SPD100220Y4B carries UL 1449 certification, a fundamental safety standard for surge protective devices. This certification validates protective performance, component reliability, and electrical safety, facilitating code compliance, supplier qualification, and acceptance in regulated facilities where surge protection is mandated.
The remote display enables real-time monitoring of surge protection status, fault conditions, and device health, enabling proactive maintenance and quicker fault isolation. This reduces mean time to repair, extends equipment life, improves asset management, and supports ongoing compliance reporting for facility operations.
