FAQs
Installation begins with verifying the bottom feed configuration and ensuring a three-pole, three-wire hookup. Connect the included control power transformer and matched CTs according to the Eaton specification sheet, noting that the CT for a neutral-neutral connection is not included. Mount the unit in a prepared panel space, secure wiring with appropriate lugs, and test continuity and insulation prior to energizing the circuit. Follow standard safety practices and de-energize the panel during wiring to prevent shock or arc flash. A correctly wired setup reduces commissioning time and improves protection reliability.
The CB1234B120480C is rated for 1200A with a 480V line voltage and a 120V control voltage. It is fusible, meaning it provides protective interruption in fault conditions, and it includes an AFGF relay with matched CTs to support accurate current sensing. This combination delivers dependable fault isolation, safer panel operation, and clear signaling for downstream control relays. UL Listed certification confirms compliance with applicable safety standards for industrial panels.
Yes. With a 1200A rating and 480V voltage handling, this switch suits high-current drives in conveyors, pumps, and other large automation equipment. The integrated control transformer and CTs simplify integration with motor controls and protection relays, enabling reliable fault detection and faster response times. When sizing, ensure your wiring, disconnects, and enclosure clearance meet applicable codes for safe operation in industrial environments.
The CB1234B120480C carries UL Listed certification, signaling conformity with recognized safety standards for industrial control devices. This certification helps streamline procurement and reduces compliance risk when designing or retrofitting control panels for regulated environments. Always reference the Eaton specification sheet for installation guidance and confirm compatibility with regional safety requirements and your organization’s internal standards.
Schedule periodic inspections of the CT connections, control transformer integrity, and fuse status to prevent unexpected trips. Verify wiring integrity after vibration or impact events and replace any damaged cables promptly. Keeping a maintenance log aligned with the Eaton spec sheet helps track performance trends, supports predictive maintenance, and reduces downtime costs by catching issues before they cause unexpected outages.
