FAQs
Installers should plan for a top-feed, fusible switch with three-pole, three-wire configuration. The unit measures 16 in by 24 in by 28 in and weighs 175 lb, so ensure adequate panel clearance, mounting supports, and access for CTs and the arc-energy reduction relay. Use matched CTs and follow ambient temperature and clearance guidelines per UL and OEM recommendations.
CB2533T120208E provides a 2500A amperage rating, 120 V control voltage, and 208 V voltage rating. It is a three-pole, three-wire, fusible design with top feed. These specs enable reliable switching of large feeders and motors, with straightforward integration into common plant voltages and robust protection during faults.
Yes. The 2500A rating, 208 V line voltage, top-feed configuration, and fusible protection make this switch well-suited for motor control centers and high-current switchgear. The included Arc Energy Reduction Relay and matched CTs further enhance safety and fault response, which is critical for MCCs operating near their thermal and voltage limits.
The CB2533T120208E carries UL Listed certification, a key safety designation recognized in many markets. This certification supports compliance with electrical safety standards, supplier qualification, and regulatory requirements for electrical protection devices used in industrial environments. Always verify regional adoption of UL listings and any local code requirements before procurement.
Benefits include reduced downtime due to safer arc-energy handling and faster fault clearance thanks to the Arc Energy Reduction Relay and CTs. The robust, top-feed design simplifies installation and service, potentially lowering labor costs. The UL Listed compliance supports long-term reliability in regulated environments, contributing to lower total cost of ownership over the switchgear lifecycle.
