FAQs
The SPM400220Y1W is designed for 127/220 V Wye (4W+G) systems and comes in a NEMA 4X enclosure with an internal circuit breaker. Its two-module design supports retrofit into standard electrical panels and is compatible with most industrial distribution gear that accepts space for a surge protector of this size. Ensure panel space and mounting provisions meet local code requirements.
This surge protection device provides 400 kA per phase protection, using two modules to clamp transient voltages and divert surges away from protected circuits. This high rating minimizes the risk of equipment damage during lightning events or switching transients, extending the life of motors, drives, controllers, and other sensitive loads.
Yes. The SPM400220Y1W uses a NEMA 4X enclosure designed for durability in outdoor and harsh environments, with internal circuit breaker protection. RoHS compliant materials further enhance reliability in demanding facilities, reducing corrosion risk and maintenance needs in damp or dusty locations.
The unit is UL 1449 and UL 1283 listed, certified under CSA Electrical Notice NO. 516 Edition 1 and CSA Std. C22.2 No. 8-M1986. RoHS compliant. These certifications support regulatory compliance, supplier qualification, and streamlined procurement for regulated industries such as manufacturing and process facilities.
The device carries a 15-year warranty from delivery, extending to 20 years with registration on Eaton’s SPD site. This long-term coverage lowers maintenance and replacement costs, improves asset management planning, and provides better return on investment for critical protection in production lines and data-intensive environments.
