FAQs
Begin by verifying the top-feed configuration and fusible protection as specified. Mount the unit securely in the switchgear enclosure, connect three wires to the 1NO-1NC contacts, and attach the ground fault transformer as applicable. Ensure control wiring is rated for 120V and that the enclosure meets the NEMA requirements for your environment. After wiring, perform a functional test to confirm proper tripping behavior and verify ground fault protection is active.
This switch is rated for 2000A amperage, with a system voltage of 480V and a control voltage of 120V. It features a 1NO-1NC contact configuration across three poles (three-wire). The device is fusible and designed for top-feed installation, with ground fault capability and a charge-before-close mechanism to improve trip reliability in protective schemes.
Best for large power distribution environments, including motor control centers, distribution panels, and central feeder banks in manufacturing or process facilities. It supports rugged operation with UL Listed certification and compatibility with common NEMA configurations, making it suitable for industrial automation and heavy-duty switchgear protection.
The CB2033T120480GAX5 is UL Listed, providing standard safety certification for electrical switchgear. It also aligns with common NEMA enclosure ratings (NEMA 1, 3R, 4, 12) for rugged environments, helping ensure regulatory compliance and durable operation in industrial installations.
The unit ships with a one-year warranty from installation or eighteen months from shipment, whichever occurs first. Optional features like Ground Fault Relay, Blown Fuse Detection, and auxiliary contacts extend monitoring and signaling, enabling predictive maintenance and SCADA integration. In exchange, you can expect reduced downtime, improved fault visibility, and lower total cost of ownership through simplified protection schemes.
