FAQs
The CB1634T120480C ships with matched CTs and an AFGF relay to simplify integration. Note that CT for neutral-neutral is not included, so verify your panel’s CT requirements and plan for any missing components prior to installation.
The unit is rated for 1600A with a 480V line voltage and 120V control voltage, three-pole, three-wire, and fusible. This combination supports high‑current motor protection while allowing standard control logic to operate the device reliably.
It is designed for enclosed circuit protection in motor control centers and power distribution panels, especially in applications requiring top-feed, compact high‑current protection with a robust control power option.
UL Listed is the primary certification for this product, indicating compliance with recognized safety standards for industrial electrical equipment and enabling safer, code‑compliant installations in many jurisdictions.
Ensure CTs are properly matched to the application, confirm the neutral-neutral CT requirement, and reference Eaton’s specification sheet for wiring diagrams and torque values. Regular inspection of connections and protective relays will minimize nuisance trips and help sustain long-term reliability.
