Eaton CB1633B120480GPAC Pringle Bolted Switch - UL Listed
Part Number: CB1633B120480GPAC
Quick Summary
Eaton CB1633B120480GPAC is a bolted pressure contact switch for motor control and protection in industrial power feeds. Field teams often wrestle with nuisance trips, slow fault isolation, and complex protective schemes. This switch integrates capacitor-trip logic and ground fault options to minimize downtime and simplify maintenance. UL Listed certification ensures safety compliance for industrial installations. It also supports compatibility with common enclosures rated to NEMA 1, 3R, 4 and 12, easing panel integration, reducing engineering time, and enabling retrofit compatibility on legacy gear. The result is improved reliability, faster fault isolation, and easier procurement with a single Eaton solution. This combination supports safer operations and scalable protection strategy across plant networks.

Eaton Specification Sheet - CB1633B120480GPAC
Three-pole, bottom-feed architecture ensures reliable phase balance and simplifies wiring in large switchgear. This arrangement reduces installation time and minimizes mis-wiring, delivering safer, more predictable protection in demanding environments. It is particularly well-suited for motor feeders and feeder connections in manufacturing plants and process facilities. The capacitor trip device enables coordinated protection and reduced inrush-related issues, improving equipment life and reducing unplanned downtime. Ground fault options and auxiliary provisions expand signaling and safety without adding external hardware, lowering maintenance costs and simplifying panel design. With a fusible protection scheme, NEMA-compatible enclosures, and a 1600A rating at 480V, it provides robust protection for high-load applications. The unit’s heavy-duty construction (200 lb) supports rugged installations, while the compact footprint fits standard switchgear spaces. Optional Ground Fault Relay, Blown Fuse Detection, Kirk provisions, and auxiliary contacts extend control flexibility. Warranty and service support from Eaton further reduce lifecycle risk. Bottom-feed configuration simplifies wiring during retrofit projects and aligns with common Eaton control architectures. In practice, the CB1633B120480GPAC delivers reliability, ease of installation, and scalable protection for industrial power systems.

FAQs
Begin with confirming panel ratings and that a bottom-feed configuration is used. Mount the CB1633B120480GPAC securely, connect three phase inputs to the three poles, wire the 120V control circuit, and install the fusible protection per the datasheet. If you plan to enable optional Ground Fault Relay or auxiliary contacts, follow the Eaton installation notes to avoid mis-wiring and ensure proper coordination with downstream protection.
The device is rated for 1600A amperage, with a system voltage of 480V and a 120V control voltage. It is designed for three-phase, three-wire configurations and provides fusible protection. The unit is compatible with NEMA 1, 3R, 4, and 12 enclosures, supporting reliable operation in a range of industrial environments, including motor feeders and switchgear circuits.
Yes. Catalog notes indicate an optional Ground Fault Relay is available, and the switch is designed for ground fault protection configurations. This feature, combined with a control power transformer option, enhances safety and fault visibility in critical loads while simplifying panel design and maintenance planning.
The CB1633B120480GPAC is UL Listed, providing recognised safety certification for industrial installations. This certification supports compliance in typical plant environments and is compatible with common protective enclosures, aiding procurement and installation decisions for motor control and feeder protection.
Eaton provides a standard warranty under policy 25-000: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. This coverage supports parts and service needs, with Eaton’s technical support available to assist with installation, commissioning, and ongoing maintenance decisions.
