FAQs
Install the SPD100220Y1O on the external side of electrical distribution equipment as specified in Eaton’s installation manual IM01005031E. Use the NEMA 4X enclosure for environmental protection, wire L-N, L-G, N-G, and L-L per the 127/220 V Wye configuration, and secure the unit to a stable surface. Follow grounding and clearance recommendations to ensure proper surge routing and service accessibility.
SPD100220Y1O is designed specifically for 127/220 V Wye systems, delivering a 100 kAIC interrupt rating and multi-line protection (L-N, L-G, N-G, L-L). The external side mounting and rugged NEMA 4X enclosure support reliable operation in typical industrial environments, with UL 1449 certification ensuring compliance and safety for panel and equipment protection.
Yes. The SPD100220Y1O utilizes a NEMA 4X enclosure, which is designed to resist water, dust, and washdown conditions. This makes it suitable for outdoor panels, exposed electrical rooms, and washdown areas. When installing, ensure proper sealing and mounting to maintain enclosure integrity and verify compatibility with external distribution equipment per the installation manual.
SPD100220Y1O carries UL 1449 certification for surge protection devices and is housed in a NEMA 4X enclosure. It has a 100 kAIC interrupt rating and is intended for 127/220 V Wye systems with external mounting. These specifications support industry compliance, reliability in harsh environments, and suitability for aggressive surge events in industrial facilities.
Installing SPD100220Y1O reduces downtime by mitigating transient overvoltages that cause equipment faults and unscheduled maintenance. Its 15-year warranty and robust enclosure lower lifecycle costs, while providing long-term protection for critical loads. The device’s simple integration with existing SPD Series products also shortens procurement and installation timelines, improving overall project ROI.
