FAQs
CB1633B120480KAX is a three-pole, bottom-feed switch designed for relatively compact panels. When wiring in tight spaces, plan for the 16 inch depth and 24 inch width, ensuring clearance for the interlock mechanism and access to the control terminals. Use the bottom feed configuration to simplify conduit layouts and minimize vertical room requirements in standard switchgear footprints.
Key specs include 1600A amperage rating, 480V system voltage, 120V control voltage, three poles, fusible protection, and bottom feed. The device is UL Listed and rated for NEMA 1, 3R, 4, and 12 enclosures, offering robust protection for industrial distributions and control panels in harsh environments.
Yes. With its 1600A rating, 480V system capability, and interlock features, CB1633B120480KAX is well-suited for motor control centers and heavy-duty switchgear. The bottom-feed design and optional protection options streamline installation, improve safety, and reduce wiring complexity in MCCs and factory automation panels.
The CB1633B120480KAX carries UL Listed certification, ensuring safety compliance for electrical equipment. It is compatible with NEMA-rated enclosures: 1, 3R, 4, and 12, which supports durability in harsh industrial environments and helps meet regulatory and installation requirements in many facilities.
Adopting CB1633B120480KAX can reduce downtime through reliable interlock protection and improved fault detection (with optional Ground Fault Relay and Blown Fuse Detection). Its robust 1600A/480V capability minimizes voltage drops and nuisance trips, while UL Listed compliance accelerates approvals, lowers maintenance costs, and shortens commissioning time in large-scale switchgear projects.
