FAQs
CB2033B120208GRAX5 supports bottom feed configurations and bottom fuse arrangements, simplifying wiring layouts in compact switchgear. When integrating into existing enclosures, verify clearances for three-pole, 1NO-1NC contacts and ensure the ground fault option (if installed) is correctly wired to the control transformer. Proper alignment minimizes field adjustments and accelerates commissioning.
The device is rated for 2000 A with a 208 V system and 120 V control voltage, configured as three-pole (three wires) with 1 NO-1 NC contacts. It is fusible and designed for robust protection in switchgear, motor control centers, and large distribution panels. UL Listed and compatible with several NEMA enclosures (1, 3R, 4, 12), supporting diverse industrial environments.
Yes. The product’s NEMA ratings (NEMA 1, 3R, 4, 12) indicate suitability for indoor and outdoor or damp environments when installed in appropriate enclosures. UL Listed certification further supports compliance with safety standards. For outdoor use, pair with weather-resistant enclosures and follow grounding and protection best practices.
Options include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. These add-ons enable enhanced fault detection, expanded signaling, and integration with broader protection schemes, helping you tailor protection to specific plant requirements while maintaining a compact footprint.
Eaton provides a standard warranty policy (25-000) with one year from installation or 18 months from shipment, whichever occurs first. Support covers reference data, compatibility questions, and replacement parts. For preventive maintenance, document service intervals and track trip history to optimize uptime and lifecycle costs.
