Eaton CB1233B120480K5 Bolted Pressure Switch - UL Listed

The CB1233B120480K5 offers a 1200 A amperage rating and 480 V system voltage, enabling management of high-power loads with a single device. This consolidation reduces equipment count, minimizes wiring complexity, and improves panel density for large motor starters and feeders in industrial switchgear. In practice, it supports reliable power distribution in manufacturing lines, water treatment facilities, and process industries. A 1NO-1NC contact configuration with an interlock feature ensures safe sequencing and prevents accidental energization during start-up. The bottom-feed design simplifies wiring guidance, reduces interior enclosure congestion, and accelerates serviceability during scheduled maintenance or fuse swaps. This combination is especially beneficial in retrofit projects where existing panels must be upgraded without extensive rework. Fusible protection paired with bottom feed streamlines fuse coordination, replacing multiple fuses with a single, clearly labeled protective element. The three-pole, three-wire arrangement provides robust switching performance across three-phase circuits while maintaining straightforward wiring schemes for technicians. Operators experience more predictable fault response and shorter troubleshooting cycles under heavy loads. Optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk provisions, and auxiliary contact provisions give engineers flexible protection schemes without adding separate devices. These options support alignment with facility safety standards, predictive maintenance practices, and industry best practices for safety interlocks. The CB1233B120480K5 integrates smoothly with existing safety relays and PLCs. UL Listed certification coupled with broad NEMA ratings (NEMA 1, 3R, 4, 12) enables compliant installations in diverse enclosures and environmental conditions. Its dimensions—16 in depth, 32 in height, and 24 in width—along with a 200 lb weight, inform enclosure planning, mounting clearances, and shipping considerations. The design supports efficient field service and reduces risk during installation and upgrades. In real-world operations, users see uptime improvements, safer gear operation, and optimized protection coordination across distribution panels and motor drives. The Eaton CB1233B120480K5 is a future-ready solution for industrial facilities demanding robust, safe, and scalable switching devices. When paired with Eaton's catalog resources and installation notes, it simplifies compliance and maintenance planning.
