Surge capacity of 300kA per phase provides robust protection for critical loads, reducing the risk of equipment damage and unplanned downtime in manufacturing lines and process controls. This capability translates to fewer nuisance trips and extended service life for pumps, drives, and PLC-based equipment. The 120/240V split-phase rating covers common industrial feeders, enabling a single protective device to serve diverse equipment stacks without complex configurations. UL 1449 certification ensures compliance with industry safety standards, while the NEMA 4 enclosure offers reliable indoor-outdoor protection against dust, moisture, and corrosion in harsh environments. An internal circuit breaker simplifies setup and code compliance, eliminating the need for external disconnects and speeding up commissioning. Power Xpert compatibility ensures seamless integration into Eaton protection ecosystems, reducing maintenance overhead and enabling centralized monitoring. The compact footprint (9.5 in depth, 15 in width, 17.05 in height) and a 52 lb form factor support sturdy, long-term installations in panel arrays and distribution setups. Installation flexibility is enhanced by the integrated design, allowing easier retrofits and faster deployment across multiple panels, MCCs, and switchgear. This combination of rugged protection and installer-friendly features supports cost-effective risk management for critical industrial assets.
