FAQs
Install as a bottom-feed, three-pole device wired for three wires. Connect to a 208 V system with a 120 V control circuit, and follow the prescribed fuse configuration for fusible protection. Ensure correct alignment with Kirk provisions and auxiliary contact provisions if used, then verify the three-light trip indication after commissioning to confirm proper operation.
The switch is rated for 2000 A with a system voltage of 208 V and a control voltage of 120 V. It provides fusible protection and supports NEMA ratings for enclosure compatibility (NEMA 1, 3R, 4, 12). It is designed as a three-pole, three-wire device with bottom feed and a charge-before-close mechanism.
Yes. Its 2000 A rating, bottom-feed configuration, and three-pole design suit large switchgear and motor control centers. UL Listed certification and alignment with common NEMA enclosures support reliable installation and regulatory compliance in industrial panels.
The CB2033B120208A9CT carries UL Listed certification, confirming safety compliance for industrial electrical installations. It is compatible with standard NEMA-rated enclosures, facilitating straightforward integration into existing panels and safety programs.
Warranty is one year from installation or 18 months from shipment, whichever occurs first. For ROI, rely on improved trip reliability and reduced downtime. Regular checks should focus on the fusible protection path, the three-light trip indicators, and validation of optional features such as Ground Fault Relay or Blown Fuse Detection during scheduled maintenance.
