FAQs
CB2033T120480K7 uses a 2 NO-2 NC contact configuration on a three-pole, top-fed, fusible design, enabling straightforward integration with standard switchgear and motor control centers. Its 120 V control and 480 V system ratings support both logic and power circuits, while optional auxiliary contacts and ground-fault provisions improve visibility and fault isolation in existing installations.
Plan for the 16 in × 28 in × 24 in footprint and approximately 180 lb weight when mounting in a dedicated enclosure. Ensure top-feed fuse configuration aligns with upstream protection devices, provide appropriate clearance for wiring, and verify compatibility with current switchgear, NEMA elevations, and mounting arrangements for safe, code-compliant installation.
Yes. The device is rated for 480 V system voltage with a 2000 A amperage rating, and it supports 120 V control voltage. This combination makes it suitable for heavy-duty distribution and interlock applications in industrial facilities, while maintaining proper coordination with upstream and downstream protective devices.
The CB2033T120480K7 is UL Listed, ensuring compliance with important safety standards. It also supports a range of NEMA configurations (NEMA 1, 3R, 4, 12), indicating suitability for various environmental conditions and installation scenarios in industrial settings.
The fusible, high-capacity design reduces arc energy and improves fault isolation, which lowers downtime and maintenance costs. Optional features such as ground-fault relays and auxiliary contacts enable better fault detection and system visibility, contributing to longer asset life, improved safety, and a faster return on investment in demanding plant environments.
