FAQs
The SPD100400Y1Q is designed for external sidemount installation on distribution equipment. Begin by ensuring the panel busbar, conductors, and protective devices are within the 230/400V wye rating. Mount the enclosure externally, connect L-N, L-G, N-G, and L-L per the installation manual, and follow the recommended wiring diagram to maintain UL 1449 compliance.
The device provides a 100 kAIC interrupt rating, suitable for industrial surge events. It supports 230/400V wye systems with operating voltages of 320 L-N, 320 L-G, 320 N-G, and 640 L-L, enabling broad compatibility with typical equipment protection schemes in factories and commercial facilities.
Yes. The unit is housed in a stainless steel NEMA 4X enclosure with an internal disconnect, designed for wash-down and exposure to challenging conditions. Its external sidemount configuration makes retrofits easier in space-constrained outdoor or rugged indoor applications such as processing plants and outdoor substations.
SPD100400Y1Q carries UL 1449 certification for surge protection devices, and is engineered with a NEMA 4X stainless steel enclosure to meet harsh-environment demands. The combination supports regulatory compliance, supplier qualification, and simplified procurement for regulated facilities.
With a 15-year warranty, the SPD provides long-term protection with reduced maintenance cycles. By limiting surge-related equipment damage, facilities can lower downtime, extend asset life, and achieve a favorable total cost of ownership in power distribution setups across manufacturing and facilities management.
