Eaton Specification Sheet - CB2033B120480KG7
Feature → Business Impact → Application: The CB2033B120480KG7 delivers a 2000A amperage rating paired with a 120 V control voltage and a 480 V system voltage, enabling it to handle high-current motor control tasks while reducing voltage-related risks. This translates to improved uptime in manufacturing lines and safer, more predictable shutdowns during maintenance. The 2 NO-2 NC contact configuration supports flexible interlocking schemes in machine centers and panel assemblies, ensuring precise control and safe start/stop sequences. Bottom feed and fusible configuration simplify wiring runs and protection coordination, cutting installation time and minimizing fault exposure in dense switchgear environments. The interlock feature enhances safety by preventing accidental energization during servicing, a critical requirement in high-energy environments. Optional Ground Fault Relay and Auxiliary Contact Provisions address advanced protection and monitoring needs, reducing unplanned downtime and improving fault diagnosis. The three-pole design and 3-wire setup provide robust control in compact footprints, improving enclosure utilization and panel density. Compatibility with Kirk provisions and auxiliary options ensures future-proofing and expandable control architectures for evolving industrial applications.

FAQs
CB2033B120480KG7 is designed for bottom-feed, three-pole installations in industrial switchgear and panelboards. It uses a 2 NO-2 NC configuration with a 2000A capacity and 480V system voltage, and it weighs about 190 lb. Ensure your enclosure provides adequate depth (16 in) and width (24 in) and supports a bottom-fed fuse configuration.
Key specifications include a 2000A amperage rating, 120 V control voltage, and a 480 V system voltage with a maximum of 480 V. It is fusible, three-pole, and uses a 2 NO-2 NC contact configuration. The switch also supports interlock, ground fault capability, and optional auxiliary contacts for enhanced protection and monitoring.
Yes. The three-pole, 2 NO-2 NC arrangement and bottom-feed configuration suit motor control centers and heavy-duty switchgear, providing reliable interlock protection and high-current switching. Its NEMA-rated enclosure compatibility (NEMA 1, 3R, 4, 12) helps ensure suitable performance in diverse plant environments.
The CB2033B120480KG7 is UL Listed, confirming compliance with recognized safety standards for electrical equipment. It also aligns with common NEMA protection classes (1, 3R, 4, 12), supporting use in a wide range of industrial enclosures and ensuring reliable operation in harsh environments.
The interlock feature reduces the risk of accidental energization during servicing, improving safety and uptime. Optional Ground Fault Relay and auxiliary provisions enable proactive fault detection and expanded control, lowering maintenance costs over the life of the installation and improving diagnostic capabilities for faster repairs and reduced downtime.
