FAQs
CB2033B120480GA9 is designed for bottom-feed, three-pole operation with a fusible configuration. Plan for secure lifting due to its 190 lb weight, ensure proper grounding with the ground fault transformer option, and verify compatibility with Kirk provisions and auxiliary contact provisions if extended monitoring is required. Use the catalog notes to specify optional features before panel assembly.
The switch provides a 2000 A amperage rating, 480 V system voltage, and 120 V control voltage, enabling protection for high-current feeders and motors. It supports fusible protection and is rated for NEMA 1, 3R, 4, and 12 enclosures, ensuring reliable operation across indoor and outdoor environments. These specs translate to robust fault protection and compatibility with common low-voltage control schemes.
Yes. The CB2033B120480GA9 is UL Listed, illustrating compliance with recognized safety standards. It also carries broad NEMA ratings—1, 3R, 4, and 12—making it suitable for a range of indoor and harsh environments typical in industrial settings. Optional features like ground fault protection further enhance regulatory alignment and safety.
This switch is ideal for heavy-duty motor control centers, feeders, and power distribution panels in manufacturing, processing, and packaging facilities. Its three-pole design, fusible protection, and bottom-feed configuration support reliable, scalable protection for large loads, while UL and NEMA compatibility simplify installation and ongoing maintenance.
Expect reduced downtime due to reliable tripping and fault detection, aided by optional ground fault and auxiliary provisions. The unit’s heavy-duty construction and UL/NEMA compliance support long service intervals, while the warranty policy (one year from installation or 18 months from shipment) provides a defined risk window. Plan for periodic inspection of fuse status and transformer ground connections to maximize uptime.
