Eaton CB4033T120480GRAR Bolted pressure switch-UL Listed

The CB4033T120480GRAR delivers high-current protection with a 4000A amperage rating at a 480V system, paired with a 120V control voltage. Feature: high-current capability and voltage versatility → Business Impact: enables single units to protect large feeders and motors, reducing panel count and simplifying procurement → Application: large distribution panels and motor feeders in petrochemical, metal processing, and pulp and paper plants. The device utilizes a single-voltage relay with a capacitor trip device (SPVR) and a ground-fault option to enhance selective tripping and fault discrimination, improving system reliability and minimizing unnecessary outages in complex lineups. This supports mission-critical processes in continuous-operation environments. The unit’s top-feed fuse configuration and three-pole, three-wire design improve installation efficiency and protection coverage, especially in retrofit projects where cabinet space is at a premium. NEMA ratings 1, 3R, 4, and 12 extend protection across harsh indoor and outdoor environments, with a rugged build that reduces maintenance cycles and extends service life. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary/ Kirk provisions provide modular protection and control expansion, helping engineering teams tailor the solution to specific safety and compliance requirements. The 390 lb footprint implies a sturdy, vibration-tolerant installation suitable for heavy-duty switchgear, while the included overview of proofs-of-performance speeds fault diagnosis and reduces downtime during maintenance windows. The combination of UL Listed certification and Eaton’s warranty support delivers confidence for long-term asset protection and regulatory compliance in industrial automation environments.
