Eaton CB4033B120208RARCT - Pringle bolted pressure contact switch UL Listed
Part Number: CB4033B120208RARCT
Quick Summary
Eaton pringle bolted pressure contact switch provides robust protection for heavy-duty electrical switchgear in industrial power distribution. This device delivers reliable single-phase protection with a capacitor trip, reducing nuisance trips and ensuring safe operation across 208 V systems. Maintenance teams often struggle with mis-trips and delayed fault indication; the SPVR and three-off lights help operators quickly verify trips and status. Certifications matter in regulated environments, and this model is UL Listed with broad NEMA compatibility for enclosures from NEMA 1 to 12. For businesses, the combination of 4000A amperage, bottom-feed configuration, and optional ground fault protection translates to improved uptime and easier retrofit.

Eaton Specification Sheet - CB4033B120208RARCT
Capacitor trip device and SPVR provide precise, fast fault clearance, reducing unplanned downtime and administrative overhead. The unit's BFD with three normally-off lights makes trips explicit to operators, decreasing investigation time and supporting safer shutdown sequences. This combination supports reliable protection for critical loads in manufacturing and process environments. Three-pole, 208 V-rated design, 4000A amperage rating, and bottom-feed configuration deliver robust control and suppression for large motors and feeders. With fusible protection, system integrators can coordinate with upstream protective devices and minimize arc flash exposure during fault events. This configuration is particularly advantageous in power distribution panels and switchgear arrays. Bottom feed fuse configuration simplifies wiring and enclosure layout, allowing compact panel design and board-to-board routing. Optional ground fault relay and auxiliary contact provisions extend monitoring and remote signaling, enabling tighter integration with PLCs and motor control centers. NEMA ratings and UL listing provide installation flexibility across indoor and harsh environments, including outdoor applications. This broad certification footprint helps meet industry standards for safety and compliance during audits. The component's rugged construction and Eaton warranty offer long-term value; with a one-year warranty from installation (or 18 months from shipment), customers gain predictable maintenance planning and peace of mind for critical power protection investments.

FAQs
In practice, ensure panel space accommodates the 22.5 in depth, 32 in height, and 40 in width footprint; verify upstream protection coordination for a 4000A rating; and confirm availability of optional features such as ground fault relay to meet site-specific fault protection requirements.
The capacitor trip device (SPVR) uses a capacitor-assisted mechanism to trigger a fast, reliable trip in response to abnormal voltage conditions, improving protection against single-phase faults and transients. This feature enhances protection coordination with upstream protective devices and reduces nuisance trips by delivering a controlled trip signal during fault events, enabling safer shutdown of protected circuits.
Yes, CB4033B120208RARCT is UL Listed, meeting established safety standards for electrical equipment. It supports multiple NEMA enclosures, specifically NEMA 1, NEMA 3R, NEMA 4, and NEMA 12, which provides installation flexibility across indoor panels, outdoor cabinets, and surrounding environments with varying degrees of exposure to dust, moisture, and contaminants.
Bottom-feed fuse configuration simplifies wiring within the panel and supports compact enclosure layouts, reducing cabinet height and wiring complexity. When retrofitting, verify conductor routing to the bottom terminals, ensure compliance with local codes, and coordinate with upstream protection. Consider optional ground fault relay and auxiliary contact provisions to enhance monitoring and integration with control systems.
The CB4033B120208RARCT offers high current capacity (4000A) and robust fault protection, which translates to fewer unplanned outages and reduced downtime. Its SPVR capacitor trip and BFD indicators streamline maintenance workflows, while UL/NEMA ratings enable flexible installation. Over time, the reliability and modular add-ons (ground fault relay, auxiliary contacts) can lower maintenance costs and improve plant-wide uptime, delivering favorable total cost of ownership.
