FAQs
The CB2033B120480K6 uses a bottom feed configuration with a bottom fuse setup and a three-pole, three-wire arrangement. Its footprint (16"L x 24"W x 32"H) and 190 lb weight require secure mounting and appropriate enclosure support. For best results, align with standard 480V panel designs, ensure clearance for 6'6" operator handling, and use the optional auxiliary contact provisions if extended control is needed.
This switch is rated for 2000A amperage with 480V system voltage and 120V control voltage. It is fusible and features an electrical trip with charge-before-close mechanism. Applicable environments include NEMA 1, 3R, 4, and 12 enclosures, making it suitable for rugged industrial installations such as large motors, conveyors, and pumps.
Yes. Safety is enhanced through interlock functionality and a handle designed for 6'6" clearance, enabling safe operation and maintenance. The design supports ground-fault protection options and auxiliary contact provisions to implement lockout/tagout and additional control circuits. UL Listed certification further confirms compliance with applicable safety standards.
The CB2033B120480K6 is UL Listed, indicating conformity with recognized safety standards. It also aligns with NEMA ratings for enclosures—specifically NEMA 1, 3R, 4, and 12—supporting use in varied environmental conditions typical of industrial facilities.
With a one-year warranty from installation or eighteen months from shipment, whichever occurs first, maintenance focus should be on inspecting the fusible protection, interlock integrity, and any optional components like auxiliary contacts or fault-detection features. Regular inspection of connections, bottom-feed wiring, and enclosure integrity will help preserve performance and minimize downtime.
