FAQs
This switch is designed for three-pole, three-wire installations with top-feed and fusible protection. It fits standard industrial panels and supports NEMA 1, 3R, 4, and 12 enclosures. Optional accessories such as ground fault relay and auxiliary contacts expand compatibility with monitoring and protection schemes used in motor control centers.
The device provides a 4000A amperage rating, 208V system voltage, and 120V control voltage. It is fusible and supports three-pole, three-wire configuration with top-feed. This combination enables reliable protection for large current feeders while allowing straightforward integration with common industrial power architectures.
Yes. With a 4000A rating and three-pole design, the CB4033T120208AXCT is well-suited for main power protection in motor control centers and heavy-load feeders. The charge-before-close mechanism also improves switching reliability in demanding motor startup scenarios, reducing inrush-related disturbances.
The switch is UL Listed and specified for multiple NEMA environments (NEMA 1, 3R, 4, 12). These certifications support compliance across many industrial installation standards and help streamline approvals for panel builders and end users.
Optional features like Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contacts provide enhanced fault sensing and visibility, enabling proactive maintenance and faster fault diagnosis. This reduces mean time to repair (MTTR), minimizes unplanned downtime, and supports long-term cost-of-ownership improvements in high-demand facilities.
