FAQs
Install the two-module SPD MAX device per manufacturer's mounting guidelines, ensuring proper bus connections to the 600 Delta(3W+G) network. Use the internal circuit breaker for local overcurrent protection and verify routing is compliant with the NEMA 4X enclosure for weatherproof installation. Route signal and power lines separately to minimize interference and maintain surge-counter visibility.
The unit provides 320 kA per phase transient surge protection. This rating safeguards critical equipment including motors, drives, PLCs, and control panels from voltage spikes, reducing equipment stress, extending life, and improving uptime in demanding industrial environments.
Yes. The device is UL 1449 and CSA certified and RoHS compliant, with an enclosure designed for rugged industrial use. This combination supports regulatory compliance, safer operation, and easier qualification for installation in facilities that require rigorous electrical protection standards.
Eaton specifies a 15-year warranty from the date of delivery, extending to 20 years when registered on Eaton’s SPD site. The built-in surge counter aids proactive maintenance by providing protection-history data, helping plan replacements before failures occur and reducing unplanned downtime.
The NEMA 4X enclosure offers reliable weatherproof and washdown-capable protection for harsh environments, enabling outdoor or damp locations. An internal circuit breaker simplifies integration by combining protection and switching in a single unit, reducing panel space, and speeding up field installation while enhancing safety and serviceability.
