FAQs
Begin with de-energizing the panel and verifying system voltage is 120/208 V. Mount the SPM400208Y4R in a suitable enclosure (NEMA 4 suitable) and connect to the 4W+G terminals per the wiring diagram. Use the internal circuit breaker to isolate the SPD for maintenance, and ensure UL 1449 compliance is upheld throughout installation.
400 kA per phase indicates the device can absorb a high-energy transient on each phase without fail, protecting sensitive electronics, drives, and IT gear from damaging energy surges. This rating is particularly relevant for environments with frequent switching transients or lightning events, helping to maximize uptime.
Yes. The 120/208 V Wye configuration with a 4W+G connection suits data centers, manufacturing lines, and motor drives. Its UL 1449 listing and NEMA 4 enclosure enable robust protection in both controlled and harsher environments, while the internal breaker simplifies maintenance and helps isolate the protection device when servicing.
The device is UL 1449 listed and features a NEMA 4 enclosure with an internal circuit breaker. Its 120/208 V Wye rating ensures compatibility with common industrial power systems, enabling straightforward integration into existing electrical rooms and panel boards while meeting essential safety and performance standards.
By preventing surge-related damage, the SPD reduces unplanned downtime and extends equipment life. The integrated internal circuit breaker streamlines servicing, and compatibility with Power Xpert SPD ecosystems supports centralized protection strategies, lowering maintenance time and total cost of ownership across multiple protected loads.
