Selling Policy 25-000 - Distribution and Control Products and Services
High-current capability and rugged enclosure deliver reduced downtime and fewer parallel devices, enabling streamlined protection coordination for MCCs and large switchgear. This translates into measurable efficiency gains, lower installation costs, and safer operation in high-load applications. The 2500 A amperage rating with a 480 V system voltage supports robust fault isolation, improving feeder reliability and arc-flash management in industrial power networks. The 1 NO-1 NC configuration provides flexible control logic for interlocks and status signaling, simplifying wiring and reducing point-of-failure risks during equipment startups. Top feed and fusible protection simplify field wiring and predictable fault clearance, while optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection extend coverage for critical lines. Interlock capability and 6 ft 6 in handle compatibility enhance operator safety and workflow in confined spaces. With three-wire design and NEMA-rated enclosure compatibility, this unit fits standard plant layouts without custom fabrication, lowering commissioning time and boosting uptime. The catalog notes on optional provisions for auxiliary contacts and Kirk provisions support seamless integration with plant controls, enabling scalable safety architectures as your system evolves.
