FAQs
Install CB3033B120208G using the bottom-feed wiring per the catalog notes and UL guidelines. Connect three live poles to the designated terminals, tie the 120 V control power via the integrated transformer, and verify grounding for the three-wire system. Use fusible protection as specified and confirm 208 V system compatibility to ensure correct operation before commissioning.
The switch is rated for 3000A with 208 V system voltage and 120 V control voltage in a three-pole configuration, plus fusible protection. This supports direct switching of large motors, simplifies coordination with upstream breakers, and reduces overall panel complexity, making it a strong fit for MCCs, switchgear, and heavy-duty panel assemblies.
This model is UL Listed and rated for multiple NEMA enclosure types, including NEMA 1, 3R, 4, and 12. These certifications ensure safety, reliability, and compatibility with harsh industrial environments, supporting compliance in regulated facilities and reducing risk during audits and inspections.
By delivering high-current protection with a built-in control transformer, the CB3033B120208G minimizes wiring errors and protection coordination issues, reducing downtime. Its rugged build and UL/NEMA compliance lower maintenance costs, while a one-year warranty (18 months from shipment) provides predictable support, contributing to a favorable total cost of ownership in demanding plants.
Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions are available to tailor the protection scheme. These accessories enable enhanced fault detection, phase protection, and expanded control options, easing integration with modern protection relays and protective interlocks in complex motor and panel architectures.
