Eaton CB4033T120480G14 Pringle pressure switch UL Listed
Part Number: CB4033T120480G14
Quick Summary
The Eaton CB4033T120480G14 Pringle bolted pressure switch provides high-current control for industrial switchgear and safety interlocks in power distribution environments. End users often face downtime and miscoordination when protection devices fail or require complex wiring, which can slow maintenance and increase risk. This device carries UL Listed certification and supports rugged NEMA ratings (1, 3R, 4, 12) for enclosure integrity, along with a built-in control power transformer and optional ground-fault features for enhanced safety. Its three-pole, three NO-3 NC configuration and top-feed, fusible design deliver rapid interruption with predictable arc quenching, reducing outage duration. In practice, it enables straightforward installation, robust protection, and scalable integration with existing motor control centers and switchgear fleets.

FAQs
The CB4033T120480G14 is designed for high-current interlocks in motor control centers and large power distribution panels. It supports 4000 A operation, three NO-3 NC contacts, and a 120 V control circuit, enabling safe, rapid interruption and reliable coordination with safety devices in industrial environments.
Yes, the CB4033T120480G14 is UL Listed. It provides a 4000 A amperage rating, a 120 V control voltage, and a 480 V system voltage. The device is three-pole with three NO-3 NC contacts, top-feed, fusible protection, and supports NEMA 1, 3R, 4, and 12 enclosures.
Consider mounting clearance for top-fed wiring, enclosure space to accommodate three-pole wiring, and compliance with UL and NEMA requirements. Plan for a control power transformer integration and ensure the available auxiliary or ground fault provisions align with your protection scheme.
Yes. Catalog notes indicate optional Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk provisions, and Auxiliary Contact provisions are available. These options enable enhanced fault detection, phase protection, and expanded signaling for monitoring and interlock logic.
Rely on the included one-year Eaton warranty from installation or eighteen months from shipment, whichever comes first. Regular inspection of contacts, fuses, and control wiring, plus periodic verification of ground fault and auxiliary provisions, helps maximize reliability and minimize downtime in demanding industrial environments.
