Eaton CB3033T120480AX5 Pringle Bolted Switch - UL Listed
Part Number: CB3033T120480AX5
Quick Summary
Eaton pringle bolted pressure contact switch is designed for high-current, fault-tolerant switching in industrial control panels. Engineers often face reliability gaps when large-current switches misbehave during startups or fault conditions. UL Listed compliance and strong NEMA ratings—NEMA 1, 3R, 4, and 12—help protect equipment in harsh environments. With its top-feed configuration, 1NO-1NC contacts, and fusible protection, the CB3033T120480AX5 delivers safer operation and faster maintenance. That translates to reduced downtime, easier installation, and robust compatibility with Eaton's accessory options and standard industrial panels.

Eaton Specification Sheet - CB3033T120480AX5
Three-pole, 1 NO-1 NC contact configuration provides a clean, decisive trip path for high-current circuits. This topology reduces arcing and improves fault isolation in motor and power distribution applications, making it suitable for machine controls, crane panels, and process lines. Fusible protection minimizes damage during faults, lowering the risk of cascading failures and simplifying fuse coordination for maintenance teams in manufacturing facilities. Top feed wiring and no ground fault design streamline installation in tall, enclosed panels, reducing wiring congestion and enhancing reliability in harsh environments. The 3000 A amperage rating paired with 480 V system voltage and 120 V control voltage enables safe, single-point protection for heavy machinery and main feeders, while UL Listed and NEMA-rated compatibility supports regulatory compliance and safer operation. Optional features such as Ground Fault Relay, Blown Fuse Detection, Auxiliary Contact Provisions, and Kirk provisions offer scalable safety and control flexibility for evolving control schemes. Real-world installations benefit from straightforward maintenance, readily available spares, and predictable trip behavior crucial for uptime and production performance.
