FAQs

Begin by confirming panel dimensions (16 in L, 24 in W, 28 in H) and ensure a sturdy mounting surface. Mount the switch on hardware compatible with three-pole, three-wire wiring and top-feed configuration. Connect main feeders for 480V, and route the 120V control circuit to the control terminals. If using optional features, install the Ground Fault Relay or auxiliary contacts per Eaton’s specification sheet and ensure compliance with UL and local codes.
Yes. The CB1233T120480K5 supports a top-feed fuse configuration and offers optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection. This allows you to tailor protection to your application while meeting safety standards. When selecting options, reference the Eaton catalog notes and the Specification Sheet to verify compatibility with your panel design and interlock requirements.
Key ratings include 1200 A amperage, 480 V system voltage (and 480 V voltage rating), and 120 V control voltage. The contact configuration is 1 NO-1 NC across three poles with three wires, and the device is fusible. These specs suit heavy-duty industrial installations such as motor control centers, power distribution panels, and safety interlock schemes in harsh environments.
The CB1233T120480K5 is UL Listed, providing recognized safety compliance for industrial equipment. It also carries broad NEMA ratings (1, 3R, 4, 12) indicating suitability for a range of enclosures and environmental conditions. These certifications help ensure installation compliance, safer operation, and smoother regulatory reviews during audits and maintenance planning.
The switch combines high current capability with modular protection options, reducing unplanned downtime and extending mean time between failures in demanding lines. The included warranties (one year from installation or eighteen months from shipment) provide risk mitigation. For maintenance, rely on Eaton’s specification sheets and spare-part compatibility notes; periodic inspection of wiring, interlock function, and fuse condition helps sustain reliability over time.
