FAQs
SPD100220Y4C is designed to work within Eaton's Power Xpert SPD ecosystem and is suitable for switchboards, busways, and panel boards (PRL1a, 2a, 3a, 3e, 4). Its 127/220 V Wye configuration and 4W+G grounding align with common industrial distributions, enabling straightforward integration and consistent protection across equipment banks.
The device provides 100 kA per phase surge current with a voltage rating of 127/220 V in a Wye configuration (4W+G). This combination supports robust transient suppression for medium- to large-scale industrial loads while remaining compatible with typical distribution systems found in factories.
Yes. SPD100220Y4C is expressly designed for use with switchboards, busways, and panel boards. Its high surge rating, UL 1449 certification, and Power Xpert compatibility make it appropriate for manufacturing environments where protecting critical loads and minimizing downtime are top priorities.
SPD100220Y4C carries UL 1449 certification, which verifies performance and safety in surge protection devices. This certification helps ensure compliance with electrical codes, reliability during transient events, and reduces project risk during installation and commissioning across industrial facilities.
By limiting surge damage, the SPD reduces maintenance costs and downtime, extends the life of protected equipment, and lowers replacement frequency. Its seamless integration with the Power Xpert SPD family and straightforward installation also lowers total cost of ownership while delivering predictable protection for critical loads.
