Eaton CB1633B120208E Pringle Bolted Pressure Switch - UL Listed
Part Number: CB1633B120208E
Quick Summary
Introducing the Eaton pringle bolted pressure contact switch, a high-current control device designed for industrial switchgear and motor control centers. The primary challenge it addresses is reliable control in tight panels where arc energy and transformer compatibility often drive downtime and maintenance costs. UL Listed certification anchors safety and compliance for common electrical enclosures, while the unit's combination of a control power transformer and Arc Energy Reduction Relay enhances protection and performance. With a 1600 A amperage rating at 120 V control voltage and 208 V operation, it supports demanding applications, and its bottom feed, three-pole, three-wire configuration eases installation in new builds or retrofit projects. The integrated CTs provide accurate current sensing for safer protection, contributing to overall asset reliability.

High-current switch rated 1600 A with 208 V main and 120 V control voltage enables you to handle large motors or feeders with fewer devices, reducing panel complexity and potential points of failure. This translates to measurable efficiency gains and simplified procurement for heavy-duty applications in industrial facilities. Arc Energy Reduction Relay paired with matched CTs mitigates arc flash risk and improves protection coordination. In practice, that means safer maintenance and faster fault indication in motor control centers and power distribution panels. Bottom feed fuse configuration and three-pole, three-wire design streamline wiring and harness routing. For retrofit projects, this makes integration with legacy hardware more straightforward and reduces installation time. Control power transformer isolates control circuits from high-power paths, improving reliability of control logic and protecting protective relays from voltage transients. UL Listed certification provides procurement confidence and easier regulatory acceptance, while dimensions of 16 in depth, 28 in height, 24 in width, and a 175 lb weight help with panel layout planning. Industry context: for Eaton switching devices in industrial automation, installing this switch can reduce downtime by minimizing component counts and providing robust fault sensing through CTs.
