Surge current
100 kA per phase
High surge current rating translates into real-world protection; the device delivers up to 100 kA per phase, reducing the risk of transformer damage, motor stalls, and sensitive electronics tripping off-line. Business impact includes fewer unplanned outages and lower maintenance costs, particularly in high-load manufacturing lines and critical process equipment. This surge protection device for switchgear supports 230/400 V Wye configurations, offering straightforward integration with standard panel buses and 4W + G grounding schemes, simplifying installation and reducing time-to-value for projects focused on reliability. The UL 1449 certified SPD provides a clear regulatory anchor, helping installers meet compliance requirements and pass inspections without last-minute redesigns. Power Xpert SPD compatibility enables a remote display interface, enabling proactive monitoring, fault history, and easier field diagnostics, which translates to lower on-site service costs and improved asset longevity. The compact footprint and measured dimensions (3.48 in depth, 12.05 in height, 7.47 in width) support efficient mounting within common switchgear enclosures, while its 6.8 lb weight makes handling and positioning straightforward during retrofits or new builds. Industry users benefit from a proven protection strategy that aligns with risk reduction, energy efficiency goals, and predictable maintenance budgets.

FAQs
The SPD100400Y4B is designed for 230/400 V Wye switchgear with 4W+G grounding and supports Power Xpert SPD remote display. Installation aligns with standard panel mounting practices, enabling quick retrofit into existing enclosures and minimizing downtime. The device provides per-phase surge protection up to 100 kA, making it suitable for heavy industrial feeders and critical loads. This integration supports centralized monitoring and consistent protection across multiple panels, reducing risk and simplifying maintenance.
The SPD100400Y4B carries UL 1449 certification, a key standard for surge protective devices, ensuring safety during transient events and compliance with electrical protection requirements. This certification supports confident deployment in industrial environments and helps satisfy regulatory and QA expectations for new installations or retrofits. While UL 1449 is the primary certification highlighted, the product is designed to align with common industrial practices for surge mitigation in switchgear assemblies.
Applications in industrial automation, manufacturing lines, and data-center-like environments benefit significantly. The device protects critical loads connected to 230/400 V Wye networks, including motors, sensors, controllers, and PLCs, by limiting transient voltages to prevent nuisance trips and component damage. Its remote display compatibility with Power Xpert SPD enables proactive diagnostics, while the robust 100 kA per phase rating supports high-load scenarios common in process industries.
The SPD100400Y4B measures 3.48 in depth, 12.05 in height, and 7.47 in width, with a weight of 6.8 lb, making it suitable for standard switchgear footprints. Ensure adequate clearance for heat dissipation and remote display wiring, and verify that the enclosure can accommodate the 4W+G grounding scheme. For retrofit projects, confirm panel space and compatible busbar layouts to streamline mounting and service accessibility.
By delivering up to 100 kA per phase protection, the SPD reduces transient-induced faults that can cause unplanned outages and equipment wear, leading to improved uptime. The remote display and Power Xpert SPD compatibility enable data-driven maintenance decisions, historical fault analysis, and quicker fault isolation, translating to lower service costs and an accelerated return on investment through longer asset life and fewer production interruptions.
