Special features
Standard with surge counter
Feature → Business Impact → Application: Two-module Max series design delivering 320 kA per phase protection enables high-energy surge absorption, reducing nuisance tripping and protecting downstream equipment. This translates to fewer unplanned outages and lower repair costs in motor drives and PLC feeders used on manufacturing lines. Application: ideal for critical loads in industrial panels where reliability and uptime are paramount. Feature → Business Impact → Application: NEMA 4 enclosure with internal circuit breaker provides rugged environmental protection and streamlined retrofits. The robust enclosure supports outdoor installations and damp plant areas, improving install flexibility and minimizing enclosure-related protection gaps. Application: outdoor switchgear, outdoor-rated panels, and damp-processing facilities. Feature → Business Impact → Application: Built-in surge counter delivers real-time protection telemetry and maintenance visibility, enabling proactive planning and reducing reaction time after events. Application: asset-intensive facilities that require traceable surge history for compliance and maintenance scheduling. Feature → Business Impact → Application: RoHS compliance and multiple certifications (UL 1449, UL 1283, CSA) minimize regulatory risk and simplify supplier qualification. This supports risk mitigation in regulated industries and accelerates procurement cycles. Application: data centers, food and beverage lines, and chemical processing plants. Feature → Business Impact → Application: 230/400 V Wye (4W+G) voltage rating aligns with common plant power distributions, reducing integration effort and voltage mismatch issues. Application: standard plant feeders, drives, and control panels across industrial automation environments.
