Feature: High-current capability and ready-for-use protection. The CB2033T120480A5 delivers a 2000A amperage rating with a 480V system voltage and 120V control voltage, packaged in a three-pole, three-wire top-feed layout. Business Impact: this combination supports large motor feeders and heavy equipment with predictable interrupt performance, reducing nuisance trips and unplanned downtime while simplifying wiring schematics for engineering teams. Application: ideal for industrial switchgear, distribution panels, and machine interfaces requiring fusible protection and clear status signaling. Feature: Flexible contact configuration and signaling. The unit uses a 1NO-1NC contact arrangement that supports interlocking, auxiliary signaling, and control-signal isolation without sacrificing protection integrity. Business Impact: enables coordination with drive starters, contactors, and alarms, improving safety margins and maintenance workflows. Application: common in control panels and motor control centers where separate control and protection paths are required and must coexist in a compact footprint. Feature: Environmental resilience and enclosure versatility. With NEMA ratings 1, 3R, 4, and 12 and fusible protection, this switch accommodates indoor, outdoor, and semi-harsh environments while maintaining safe operation. Business Impact: reduces enclosure upgrades and regulatory risk, supporting long-term asset reliability. Application: suitable for factory floors, outdoor substations, and wash-down areas in manufacturing and processing facilities. Feature: Optional protection and diagnostics. Catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, single-phase protection, auxiliary contacts, and Kirk provisions are AVAILABLE. Business Impact: provides enhanced fault detection, faster diagnostics, and safer maintenance routines, with modular add-ons that scale with evolving safety requirements. Application: retrofit-ready into existing switchgear or OEM-installed equipment to meet evolving safety and protection standards. Feature: Installation efficiency and lifecycle value. Top feed and fusible protection simplify wiring, reduce cabinet depth, and streamline installation in new builds or upgrades. Business Impact: lowers total cost of ownership by shortening commissioning time, minimizing field rework, and extending service intervals due to robust construction. Application: ideal for distributed control architectures, power distribution panels, and high-demand industrial facilities seeking reliable, durable protection.
