FAQs
CB4033T120208KGA9 is a top-feed, three-pole switch for large three-wire industrial panels. Plan a substantial mounting footprint (about 40 in W Ă— 28 in H Ă— 17 in D) and a 390 lb weight, with secure enclosure and proper panel supports. Use the interlock and charge-before-close features to prevent arcing during startup.
Optional Ground Fault Relay, Blown Fuse Detection, and Single Phase Protection are available to improve fault diagnosis and reduce downtime. These features help isolate issues quickly, protect personnel, and simplify maintenance planning, especially in environments with high fault potential or demanding uptime requirements.
The switch provides a 4000A amperage rating at 208V with 120V control voltage and fusible protection. It is compatible with NEMA 1, 3R, 4, and 12 enclosures and is UL Listed, ensuring broad applicability in industrial control panels and harsh environments.
The unit includes an interlock with three normally-on lights that trip the switch, offering clear status indicators for operators. These features, together with a charge-before-close mechanism, minimize operator errors, improve safety during maintenance, and protect equipment from startup transients within complex control wiring.
Eaton provides a standard warranty per Selling Policy 25-000, typically one year from installation or eighteen months from shipment, whichever occurs first.
