FAQs

This model uses a bottom feed, three‑pole configuration with fusible protection and a 208 V system rating, making it compatible with many standard switchgear footprints. Ensure enclosure supports NEMA 1, 3R, 4, or 12, and verify the control voltage matches your control circuit (120 V). Pre‑assembly with auxiliary contacts is available if required.
SPVR stands for single‑phase voltage relay with a capacitor trip device. It provides a controlled, capacitive trip sequence to avoid delayed or erratic trips, improving protection reliability in single‑phase circuits. This reduces downtime due to mis‑trips and helps protect motors and feeders from premature or delayed disconnections.
Yes. The catalog notes indicate availability of an optional Ground Fault Relay and Blown Fuse Detection. Adding these features enhances fault sensing, improves protection coordination, and supports compliance with preventive maintenance programs. Ensure wiring diagrams for the specific options are followed during installation.
The unit carries NEMA ratings for protection in diverse environments, including NEMA 1, 3R, 4, and 12 enclosures. This makes it suitable for indoor control rooms, outdoor mounted panels, and weather‑exposed installations common in industrial facilities, with UL Listed assurance for US regulatory compliance.
By delivering reliable single‑phase protection with a robust SPVR trip and optional diagnostics, the CB1233B120208RAX reduces unplanned downtime and maintenance frequency. Its compatibility with common plant voltages (120 V control, 208 V system) and modular options streamline spare parts, retraining, and retrofit projects, delivering lower total cost of ownership over the equipment lifecycle.
