FAQs
Begin by confirming panel space and enclosure rating suitable for a three-pole, top-fed fusible switch. Mount the unit in a standardized enclosure, connect three phase wires to the input terminals, and connect the 120V control circuit. If you require ground fault protection, configure the optional relay and auxiliary contacts as per the harness diagram. Verify clearance and torque specs, then perform a functional test before commissioning.
The base CB4033T120480RA9CT does not include ground fault protection by default. It supports optional Ground Fault Relay as an accessory, allowing you to add ground fault protection if your application demands it. For single-phase protection with capacitor trip, SPVR features are built in, offering reliable trip control alongside optional protective enhancements.
Yes. The switch is rated for 480V systems and 4000A amperage, with three-pole, three-wire configuration and fusible protection, making it well-suited for large motor drives, main feeders, and heavy distribution panels in industrial environments. Its SPVR and trip lights support rapid fault recognition, which is crucial in high-demand applications.
The CB4033T120480RA9CT is UL Listed, indicating compliance with safety standards. It supports enclosure ratings including NEMA 1, NEMA 3R, NEMA 4, and NEMA 12, enabling deployment in varied environments from indoor panels to exposed outdoor installations. Optional features like ground fault relay can further align the device with site-specific regulatory requirements.
Eaton provides a one-year warranty from installation or 18 months from shipment (whichever occurs first) under Selling Policy 25-000. The robust construction, high current rating, and available options (ground fault, auxiliary contacts) reduce downtime risk and maintenance costs, delivering favorable total cost of ownership in mission-critical power distribution.
