Quick Summary

Eaton CB1233B120480AX7 bolted pressure contact switch delivers high-current control for power distribution panels. Too often engineers contend with switches that fail under peak loads or require complex wiring. This unit carries UL Listed certification and NEMA ratings of 1, 3R, 4, and 12, reinforcing safety and reliability. With 1200 A and 480 V capabilities plus a 120 V control circuit, it fits both main feeders and protective interlocks. By combining a bottom-feed, fusible design with 2NO-2NC contacts, it streamlines installation and minimizes panel space while boosting uptime. Engineers benefit from compatibility with Eaton switching devices, straightforward wiring diagrams, and reduced total cost of ownership across industrial automation environments.

FAQs

CB1233B120480AX7 is designed for bottom-feed installation with a fusible config and 3-wire setup. When wiring, ensure correct alignment of the 2 NO-2 NC contacts to your interlock and control circuits, maintain 120 V control voltage routing separate from 480 V line conductors, and verify grounding practices in line with UL and NEC guidelines to maximize safety and reliability.
This model carries UL Listed certification and is rated under NEMA for 1, 3R, 4, and 12 enclosures. These ratings confirm suitability for various indoor and outdoor environments, including washdown areas, and help streamline procurement, installation, and regulatory compliance in industrial facilities.
Yes. With three poles and a 2NO-2NC configuration, the CB1233B120480AX7 supports multi-phase control and protective interlocks in motor control centers and power distribution panels. Its bottom-feed design and fusible protection simplify integration in compact enclosures while maintaining robust interlock and fault-detection capabilities.
The product carries Eaton’s standard warranty policy (25-000): one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance focuses on verifying tripping integrity, checking fuse condition, and confirming control voltage integrity, with Eaton’s documentation and service resources available for field support.
By consolidating control, protection, and fault-detection in a single 1200 A device, it reduces component count, lowers wiring complexity, and minimizes downtime due to nuisance trips. Its UL/NEMA compliance supports faster approvals, while the bottom-feed fusible design simplifies panel layouts, delivering lower total cost of ownership in heavy-duty electrical installations.
