Eaton CB1233T120480KAX Pringle bolted pressure contact switch - UL Listed
Part Number: CB1233T120480KAX
Quick Summary
The Eaton CB1233T120480KAX bolted pressure contact switch protects high-current feeders in industrial switchgear. Nuisance trips, limited fault protection, and wiring complexity often slow maintenance and raise safety risk on critical lines. UL Listed certification and rugged NEMA-rated enclosures support compliant deployments across indoor and outdoor environments. This design emphasizes reliable top-feed protection, interlock control, and optional ground fault or single-phase protection to support scalable, cost-efficient power distribution. By combining robust current handling with flexible protection options, it helps engineers meet code requirements while reducing downtime and lifecycle costs.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature: Three-pole bolted pressure contact switch rated at 1200A handles large feeder loads with decisive, fast-acting trips essential for heavy-duty motor control. Business Impact: This high current capability reduces contact wear, minimizes thermal cycling, and lowers maintenance downtime in demanding industrial environments. Application: Ideal for main feeders in industrial switchgear and large motor circuits where predictable protection and durable performance are non-negotiable. Feature: System voltage up to 480V with 120V control voltage and top-feed, fusible protection, enabling compact, coordinated protection schemes. Business Impact: Coordinated line and control protection simplifies wiring diagrams, speeds installation, and minimizes fault propagation across panels. Application: Suitable for new builds or retrofits in factories and processing facilities that require robust overcurrent protection and reliable fault isolation. Feature: Interlock and BFD with no lights provide clear status indicators while ensuring safe maintenance sequencing and protection against inadvertent energization. Business Impact: Enhances operator safety, supports strict lockout-tagout procedures, and reduces the risk of injury during service work. Application: Widely used where personnel must verify gear position before servicing critical lines in power distribution and packaging facilities. Feature: NEMA-rated enclosure options—NEMA 1, 3R, 4, and 12—extend installation versatility across indoor and outdoor environments. Business Impact: Enables outdoor installations and harsh-environment use with appropriate enclosure protection, reducing enclosure-related failures. Application: Fits manufacturing floors, outdoor substations, and control rooms with varied exposure to dust, moisture, or temperature swings. Feature: UL Listed certification confirms safety compliance, with optional Ground Fault Relay, Blown Fuse Detection, and Single-Phase Protection for flexibility. Business Impact: Streamlines procurement, reduces regulatory risk, and enables tailored protection to meet evolving codes and plant standards. Application: Ideal for projects demanding rigorous safety certification and adaptable protection configurations for ongoing process control.
