FAQs
When installing the CB1233B120480KA95, plan for a bottom-feed arrangement with three wires and a 1NO-1NC contact set. Ensure proper interlock wiring, observe the charge-before-close sequence, and verify UL Listed compliance. Use compatible auxiliary provisions when adding optional features to maintain safe, code-compliant operation in the panel.
Key ratings include 1200A amperage and 480V system voltage with a 120V control circuit. The3-pole, 1NO-1NC configuration supports reliable three-phase protection, while fusible protection provides a clear fault path. These specs ensure safe isolation, reduced arc energy, and compliance with industrial protection standards in high-load applications.
Yes. It features interlock with a fault indication system (BFD with three normally off lights that trip the switch), a robust three-pole design, and bottom-feed wiring. Optional features like ground fault relay and blown fuse detection further enhance fault signaling and safety, making it suitable for safety-critical switchgear and control panels.
The device is UL Listed and supports multiple NEMA enclosures, specifically NEMA 1, 3R, 4, and 12. These certifications ensure compliance with safety and environmental requirements for industrial switchgear, panels, and enclosures in diverse facility environments.
Maintenance focuses on interval inspection of interlock signaling, fusible protection, and any optional protective features. The 1NO-1NC arrangement simplifies diagnostics, while UL/NEMA compliance reduces rework during audits. ROI is driven by lower downtime, reduced component counts, and safer, more reliable protection in high-current applications.
