FAQs

For top-feed installations, ensure proper clearance and secure mounting within a UL-listed enclosure that supports NEMA 1/3R/4/12 ratings. Verify conductor sizing for 2000A service, confirm correct fuse configuration, and route feeders to minimize resistance and heat buildup. Remote fault indicators should be wired per interlock and BFD light guidelines.
A 2000A rating allows the switch to handle high-current feeders and motor starting surges without nuisance tripping. Design considerations include selecting compatible conductors, proper overcurrent protection, and ensuring parallel protection coordination with downstream devices to prevent cascading trips and maintain continuous production.
Yes, the CB2033T120480KGA9 is UL Listed, providing regulatory compliance for industrial electrical installations. It supports enclosure ratings compatible with NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 environments, enabling use in dry,wet, and harsh environments with appropriate mounting and protection.
This switch excels in high-current power control for industrial panels, switchgear, and process lines requiring robust interlock protection, top-feed configurations, and ground-fault sensing options. It is particularly advantageous in large motor drives, safe-stop interlocks, and applications demanding reliable fault detection and protection in challenging environments.
Facilities can expect reduced downtime due to fewer nuisance trips, faster fault diagnosis with three-light interlock indicators, and simplified maintenance through top-feed access and fusible protection. The UL Listing and compatible NEMA enclosures also lower compliance risk and enable longer service intervals, contributing to a favorable total cost of ownership.
