Selling Policy 25-000 - Distribution and Control Products and Services
Three-pole construction with bottom feed and fusible protection reduces wiring complexity and enclosure footprint, enabling safer, neater installations and easier maintenance in busy switchgear zones. Business impact: lower wiring errors, faster commissioning, and improved safety during reconfigurations in motor control centers and distribution panels. Application: suitable for large feeders and heavy-duty distribution where reliability matters. The unit’s 2000A amperage rating cuts the number of devices needed on a bus, delivering tangible cost savings and simplified spare parts management in plant upgrades. Application: large drives, feeders, and MCCs benefit from fewer components and simplified protection schemes. It operates on 208V systems with a 120V control voltage, allowing seamless integration with standard plant controls and PLC I/O. Business impact: reduces control wiring customization while improving response times in critical protection scenarios. Application: control panels, switchgear rooms, and automation racks where fast, predictable trips are essential. Interlock capability and optional ground fault relay, blown fuse detection, single-phase protection, auxiliary contacts, and Kirk provisions address safety and compliance requirements directly. Application: safety-critical installations in hazardous environments where quick fault isolation minimizes downtime and extends equipment life. The UL Listed rating and built-in NEMA compatibility ensure rugged performance in harsh environments, supporting compliance with industry standards and reducing maintenance overhead over the product life. Business impact: long-term reliability and lower total cost of ownership in industrial automation projects.
