Eaton Specification Sheet - CB1233T120480GRAX6
High amperage capability: The CB1233T120480GRAX6 carries a 1200A amperage rating, enabling it to handle large motor starts and feeder loads without compromising protection. This translates to enhanced system uptime and fewer false trips on demanding 480 V distributions. In practical panel installations, engineers gain headroom for startup surges while maintaining safe, code-compliant coordination with upstream protective devices. Three-pole, 480 V capability: Featuring a three-pole, top-fed design, this switch aligns with common industrial switchgear and simplifies wiring in tight enclosures. The compatible top-feed fuse arrangement reduces field wiring complexity and supports clean separation between line and load. Capacitor-trip protection: The SPVR device provides a capacitor-triggered trip with a charge-before-close mechanism, offering precise coordination and faster clearance on single-phase circuits. This minimizes arc flash exposure and improves reliability in switching operations across 480 V panels. Ground-fault protection: Ground fault relay option with control power transformer provides sensitive ground fault detection and safe shutdown in critical applications. Optional features like ground fault relay, blown-fuse detection, and auxiliary contacts support advanced diagnostics and more flexible protection schemes. Robust enclosure and installation compatibility: With dimensions of 16 in depth, 28 in height, and 24 in width, and a weight around 180 lb, the unit is designed for standard industrial enclosures and is easier to mount in purpose-built switchgear racks. The UL Listed rating and NEMA compatibility ensure dependable operation in harsh environments, reducing maintenance visits and extending service intervals.

FAQs
When installing CB1233T120480GRAX6, plan for a top-fed, three-pole 480V circuit within a suitable enclosure. Ensure adequate clearance for the 16 x 24 x 28 inch footprint and weight of roughly 180 lb, use appropriate mounting hardware, and verify compatibility with optional accessories such as ground fault relays and auxiliary contacts. Adhering to UL and NEMA guidelines supports reliable, compliant operation.
The SPVR capacitor trip device provides a controlled, capacitor-triggered trip that improves coordination with downstream devices. This reduces nuisance trips during normal transients and short surges while ensuring fast and reliable clearance for single-phase faults. In 480V systems, SPVR helps balance reliability with selectivity, contributing to safer startup sequences and less process disruption.
Yes. The CB1233T120480GRAX6 is designed for 480V applications and features a three-pole configuration suitable for three-wire systems. It supports top-feed fuse arrangements and is compatible with three-pole protection schemes found in standard industrial switchgear. Verify that the enclosure and wiring practices align with local codes and the NEMA ratings (1, 3R, 4, 12).
CB1233T120480GRAX6 carries UL Listed certification and is compatible with NEMA ratings 1, 3R, 4, and 12. These certifications assure regulatory compliance, enclosure protection performance, and safety across industrial environments. For procurement, the UL listing and NEMA compatibility simplify cross-site approvals, reduce compliance risk, and support maintenance planning in regulated facilities.
Expect improved uptime from a high-capacity 1200A switch designed for demanding motors and feeders, with fewer nuisance trips due to SPVR protection and accurate trip coordination. The broad enclosure ratings and optional diagnostics (ground fault, blown fuse detection, auxiliary contacts) enable proactive maintenance, faster fault isolation, and lower total cost of ownership through reduced downtime and service visits.
