Eaton Specification Sheet - CB2533T120208GR
Feature: Single-phase voltage relay with capacitor trip device (SPVR) provides a precise, fast-trip action that limits fault energy and reduces motor wear. Business Impact: Shorter fault durations lowers arc energy, extends motor life, and decreases unplanned downtime. Application: Ideal for large single-phase motors in HVAC, pumps, and process equipment in industrial facilities. Feature: Three-pole, top-feed, fusible protection with ground fault capability creates a compact protection module for switchgear. Business Impact: Simplifies wiring layouts, improves safety margins, and reduces aftermarket fuse-related failures. Application: Suitable for rugged switchgear assemblies in manufacturing lines and water treatment plants. Feature: UL Listed with wide NEMA compatibility (NEMA 1, 3R, 4, 12) and optional ground fault relay, auxiliary contact provisions. Business Impact: Supports regulatory compliance, safer maintenance routines, and easier retrofits. Application: Fits commercial distribution panels and industrial control enclosures with limited space. Feature: Large footprint and weight (28 in W x 28 in H x 17 in D; 205 lb) designed to mount in standard equipment rooms or within switchgear enclosures. Business Impact: Reduces integration risk, speeds installation, and enables reliable protection in existing layouts. Application: Ideal for high‑demand facilities needing robust, easy‑to‑source protection devices.

FAQs
CB2533T120208GR features a top-feed fuse configuration and three-pole design that aligns with standard switchgear footprints. Its 28 in width and 28 in height fit common enclosure spaces, simplifying mounting and wiring. Ensure your panel supports a 208 V system and can accommodate the SPVR timing characteristics for capacitor-tripped protection.
SPVR provides a capacitor-assisted trip that reduces inrush energy and improves trip accuracy during fault conditions. This minimizes mechanical stress on motor windings and reduces nuisance trips, leading to longer motor life, fewer unplanned outages, and lower maintenance costs in heavy-duty applications.
Yes, the CB2533T120208GR carries UL Listed status and supports NEMA ratings including outdoor-compatible configurations (3R, 4, 12 depending on enclosure). When used with appropriate enclosures and grounding, it maintains protection performance in challenging environments typical of industrial facilities.
The device is UL Listed and designed to meet common industrial safety standards. Its NEMA ratings indicate recommended enclosure compatibility for various indoor and outdoor service conditions. Optional features like ground fault relay and auxiliary contacts further support safety compliance in critical process environments.
By delivering precise single-phase protection with reduced fault energy, the switch lowers motor wear and downtime, extending equipment life and reducing maintenance costs. Its compatibility with Eaton Switching Devices streamlines procurement, inventory management, and retrofit projects, accelerating time-to-value in motor control applications.
