Eaton CB1633B120480G5 Bolted pressure switch - UL Listed
Part Number: CB1633B120480G5
Quick Summary
Eaton pringle bolted pressure contact switch is a rugged, high-current solution for industrial power distribution and switchgear protection. It streamlines protection schemes by integrating a control power transformer with 1600A, 480V capability, simplifying wiring and reducing panel clutter. Designers often struggle with coordinating protective relays, fusing, and control power in large feeders; this unit consolidates those functions into a single enclosure. The product carries UL Listed certification and supports NEMA 1, 3R, 4, and 12 environments, expanding its suitability across indoor, outdoor, and wet/dusty locations. In practice, it delivers robust reliability, a compact footprint, and faster installation for critical motor and process circuits.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature: Amperage up to 1600A enables direct connection to large feeders, reducing the need for intermediate fusing and extra wiring. Business impact: lowers installed cost, minimizes voltage drop, and speeds commissioning in heavy-duty switchgear. Application: large motor feeders in manufacturing, mining, and processing facilities. Feature: Integrated control power transformer with 120 V control voltage. Business impact: simplifies control wiring, shortens panel layouts, and improves protection trip response. Application: control circuits in main switchboards and remote annunciation panels. Feature: Bottom feed and bottom fuse configuration with three-pole, 1NO-1NC contact arrangement. Business impact: eases installation in tight or bottom-access panels and supports straightforward maintenance. Application: retrofit projects and new installs in compact enclosures. Feature: Ground fault options and optional auxiliary provisions (Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, Auxiliary Contacts). Business impact: enhances safety compliance and diagnostic capability, reducing downtime and improving incident response. Application: critical process lines and safety-critical feeds. Feature: NEMA-rated enclosure compatibility (NEMA 1, 3R, 4, 12) and fusible protection for rugged environments. Business impact: broad deployment across indoor, outdoor, and washdown environments with proven reliability. Application: chemical plants, water/wastewater facilities, and heavy industry. Feature: UL Listed certification and a robust 1-year warranty. Business impact: regulatory confidence for procurement and reduced risk of non-compliance across supply chains. Application: enterprise-grade electrical protection in mission-critical systems.

FAQs
Plan for bottom-feed mounting within compatible enclosures, accommodate a 200 lb unit, and provide secure anchoring. Verify 480V system compatibility, ensure proper wiring to the 120V control circuit, and reference the Eaton datasheet for recommended mounting clearances and wiring diagrams. The integrated control transformer reduces external wiring needs and simplifies commissioning.
With a 1600A amperage rating, three-pole configuration, fusible protection, and a 480V system voltage, this switch handles large feeders efficiently. The 1NO-1NC contact arrangement provides flexible control, while bottom feed and control power transformer streamline installation and maintenance in demanding industrial environments.
