FAQs
Begin by confirming space within the enclosure and ensuring the switch matches the existing three-pole, three-wire configuration. Use the top-feed fuse arrangement as specified, secure the unit to a rigid mounting surface, and connect 120V control voltage to the control circuit while tying the 480V feeder lines to the main terminals. Verify UL Listed compliance and perform a careful insulation check before energizing.
The CB1233T120480 is rated for 1200A at 480V with a 120V control circuit. It is a three-pole, three-wire, fusible switch using a pringle bolted pressure contact design and features a charge-before-close mechanism. The product supports NEMA configurations including 1, 3R, 4, and 12, and is UL Listed, ensuring safety and compatibility across common industrial applications.
Yes, its NEMA ratings include 3R and 4, which provide enclosure protection suitable for outdoor and damp environments, as well as rugged indoor settings. The UL Listed certification reinforces safety and reliability in challenging plant conditions. For outdoor use, ensure the enclosure and mounting conform to the corresponding NEMA rating and environmental requirements.
CB1233T120480 carries UL Listed certification, signaling compliance with recognized safety standards for electrical equipment.
