FAQs
CB2533T120480KPAXC is configured for top-feed, three-pole wiring and 480V systems with a 120V control circuit. It supports fusible protection and is compatible with NEMA 1, 3R, 4, and 12 enclosures, enabling installation in a wide range of industrial switchgear and control panels.
With a 2500A amperage rating at 480V and a control circuit at 120V, this switch provides robust protection for large motors and heavy loads. The interlock and capacitor trip device improve fault handling, while fusible protection supports selective coordination and safer shutdowns.
Yes. The unit is UL Listed, confirming safety compliance for industrial electrical equipment. It is also designed to fit widely used enclosures with NEMA 1, 3R, 4, and 12 ratings, helping ensure regulatory alignment across diverse facilities.
The interlock mechanism ensures the switch cannot close under unsafe conditions, while the capacitor trip device enables a controlled, rapid trip sequence in single-phase protection scenarios. This combination reduces nuisance trips and protects connected motors from fault-induced damage.
Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions are available to tailor protection schemes. These options support enhanced fault diagnosis, selective coordination, and extended control flexibility for complex process lines and critical equipment.
