Surge current
100 kA per phase
High surge rating of 100 kA per phase protects motors, drives, and control panels, reducing failure risk and maintenance costs. This translates to fewer unplanned outages and a longer mean time between failures, enabling production lines to run more reliably in manufacturing environments. The 127/220 V Wye (4W+G) configuration supports common 4-wire plus ground electrical layouts, simplifying integration with existing power distribution and control circuits. A NEMA 1 flush enclosure provides compact, indoor-protective installation that minimizes footprint while maintaining safe access for service. UL 1449 listing adds regulatory confidence, supporting compliance audits and supplier qualification processes. Power Xpert SPD compatibility enables centralized protection management across critical loads, while the robust enclosure and modular design facilitate straightforward retrofits in aging facilities. Finally, the device’s dimensions and weight support easy mounting in standard electrical racks or panels, helping technicians save time during installation and service.

FAQs
Installation requires mounting the unit in a sheltered indoor location, connecting the four wires plus ground (4W+G) to the device input, and securing it within a NEMA 1 flush enclosure. Ensure proper alignment with Power Xpert SPD wiring guidelines and verify UL 1449 compliance. Use appropriate wire gauges and follow OEM mounting dimensions for a secure, serviceable setup.
The SPD100220Y4L delivers 100 kA per phase surge capability, providing robust suppression for transient events. It is UL 1449 listed and designed for 127/220 V Wye (4W+G) configurations, making it suitable for protecting sensitive equipment such as drives, controllers, and distribution panels in industrial environments.
Yes. With a 100 kA per phase rating and a Power Xpert SPD interface, it fits industrial control panels, motor control centers, and other critical protection points. The compact NEMA 1 enclosure supports indoor installations, while the 127/220 V Wye rating covers a broad range of control circuits common in manufacturing and data-driven facilities.
SPD100220Y4L is UL 1449 listed, confirming its surge protection performance. The device is housed in a NEMA 1 flush enclosure suitable for indoor use. This combination supports regulatory compliance, supplier qualification, and safer, more predictable electrical protection across industrial systems.
The unit is designed for long-term, maintenance-light operation typical of SPD products with rugged construction and UL-certified protection. By mitigating repeated surge events, it reduces wear on downstream components, lowers preventive maintenance needs, and extends the life and reliability of protected equipment, driving lower total cost of ownership over time.
