Part Number: CB2533T12048056
Quick Summary
Eaton CB2533T12048056 Pringle bolted switch provides high-current isolation for heavy-duty electrical control panels. Engineers struggle with bulky disconnects that hinder maintenance and drive downtime. It is UL Listed, compatible with NEMA 1, 3R, 4 and 12 enclosures, rated for 480 V applications. Ideal for heavy-duty electrical switchgear, top-feed configurations, and fuse-protected circuits, it helps reduce downtime and support regulatory compliance. The 2500 A, three-pole design supports high-load switching with a safe charge-before-close mechanism. Optional ground fault relay, blown fuse detection, single-phase protection, and auxiliary contacts simplify retrofit projects and ongoing maintenance. Constructed for rugged environments, its 480 V system rating and UL certification support compliance across industrial facilities and maintenance programs.

FAQs
To install CB2533T12048056, mount the switch in a compatible enclosure using the top-feed configuration, connect three wires for 3-pole operation (three wires total), and wire the 120 V control circuit. Ensure appropriate clearances and tighten all connections to spec. If you plan a retrofit, verify available auxiliary contact provisions and optional ground fault options before final wiring.
This switch excels as a main disconnect in heavy-duty switchgear, motor control centers, and process-line panels. Its 2500 A rating, 480 V system voltage, and 1NO-1NC contact arrangement support high-load, high-reliability isolation in manufacturing, mining, and energy sectors where uptime is critical.
CB2533T12048056 is UL Listed and compatible with NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosures. This combination supports installations in harsh environments and aligns with common industrial safety standards, simplifying compliance for regulated facilities.
Optional features include Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, and Auxiliary Contact Provisions. These options enable enhanced safety monitoring, improved fault diagnosis, and easier system retrofits without a full panel rewrite.
Verify amperage rating of 2500 A, system voltage 480 V, control voltage 120 V, and the 3-pole 1NO-1NC configuration. Also confirm top-feed wiring, fusible protection, and enclosure compatibility to ensure seamless integration into your existing switchgear and panel layout.
