Eaton Specification Sheet - CB2033T120480GRAR
Feature → Business Impact → Application: The device is a three-pole, three-wire switch with a high amperage rating of 2000A and a 480 V system voltage, enabling robust protection for large feeders and motor circuits in manufacturing facilities. This translates to reduced downtime and safer startup sequences in panel assemblies and switchgear, particularly in high-load applications where fault currents are common. Feature → Business Impact → Application: Top feed fuse configuration and top feed design simplify wiring layouts, accelerating installation and improving serviceability in cramped panel spaces, while providing reliable top-entry access for maintenance crews. Feature → Business Impact → Application: Ground fault with control power transformer and optional ground fault relay support enhanced safety and compliance, helping plants meet strict protection standards without redesigning existing infrastructure. Feature → Business Impact → Application: SPVR capacitor trip device with BFD indicators delivers precise, predictable trips and fast fault clearance, minimizing arc-flash exposure and enabling quicker restoration of power in critical production lines. Feature → Business Impact → Application: NEMA-rated enclosure compatibility (NEMA 1/3R/4/12) ensures performance in diverse environments, from cleanrooms to dusty or damp industrial floors, reducing enclosure substitutions and inventory complexity. Feature → Business Impact → Application: Optional auxiliary contact provisions and Kirk provisions facilitate integration with remote monitoring and interlock schemes, supporting modern industrial IoT and automation architectures. These features collectively improve reliability, streamline maintenance, and reduce total cost of ownership for switchgear installations in process and discrete manufacturing environments.

FAQs
Yes. The CB2033T120480GRAR is a three-pole, three-wire switch designed for top-feed configurations with a top-feed fuse arrangement, making it straightforward to install in standard Eaton panelboards and switchgear without extensive rewiring or adapters.
The switch handles up to 2000A with a system voltage of 480V and a control voltage of 120V. It supports single-phase protection with a capacitor trip device (SPVR) and is compatible with fusible protection schemes for reliable operation in demanding environments.
Ideal for motor control centers, switchgear, and feeder panels in manufacturing and process industries, especially where high-current protection, top-fed wiring, and reliable fault clearance are critical to minimize downtime and protect expensive equipment.
This unit is UL Listed and supports NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosure ratings, enabling versatile installations across indoor and semi-exposed environments while meeting standard safety requirements.
The design reduces nuisance trips, simplifies installation, and allows optional ground fault protection and auxiliary contacts for remote monitoring. Combined with Eaton's warranty policy, this lowers downtime, improves safety, and delivers a solid return on investment through longer mean time between failures.
