Eaton CB3033T120208KR Switch - UL Listed
Part Number: CB3033T120208KR
Quick Summary
Eaton CB3033T120208KR bolted pressure switch for interlock protection in industrial control panels. Operators and maintenance teams face downtime when protection schemes miscoordinate with high-current devices; this switch addresses those pain points with a robust trip mechanism. UL Listed and compatible with NEMA 1, 3R, 4, and 12 enclosures help meet safety codes, while its SPVR capacitor trip device provides accurate, latch-safe protection. This blend of rugged construction and documentation accelerates procurement and reduces lifecycle risk. Designed for high-demand environments, it supports three-phase, three-wire configurations and top-feed fuse schemes that many panel builders specify. By consolidating protection, interlock, and trip functions in a single device, teams can shorten wiring diagrams and simplify preventive maintenance.

FAQs
CB3033T120208KR offers a three-pole, three-wire configuration with top-feed fuse options, UL Listed protection, and compatible enclosure ratings (NEMA 1, 3R, 4, 12). This simplifies retrofits and new builds alike, as it fits standard control panels and aligns with common motor control center layouts. Verify bus rating and space for top-feed wiring before mounting.
SPVR stands for capacitor trip device with a voltage relay that provides a pre-charge and close-on logic to prevent capacitor-induced faults. In CB3033T120208KR, the SPVR feature ensures a reliable trip sequence before the switch closes, reducing the risk of arcing and protecting motors during startup and fault events in high-current applications.
Yes. The unit is designed for 208V system voltage with a 120V control circuit and supports a 3000A amperage rating. This makes it well-suited for large motor loads and equipment fed from common industrial power distributions, while maintaining a reliable control signal at 120V for relays and contactors.
CB3033T120208KR is UL Listed and compatible with NEMA 1, NEMA 3R, NEMA 4, and NEMA 12 enclosure standards. These attributes support code compliance, safe operation in demanding environments, and straightforward panel integration across manufacturing, processing, and industrial facilities.
The device’s robust construction and integrated interlock/SPVR protection reduce unplanned downtime, simplify wiring, and shorten commissioning. Regular checks should focus on contacts, wiring integrity, and enclosure seals. The result is lower maintenance costs, improved uptime, and faster fault diagnosis in high-current applications.
