Eaton CB3033T120480GAR7 Pringle bolted switch - UL Listed
Part Number: CB3033T120480GAR7
Quick Summary
CB3033T120480GAR7 pringle bolted pressure contact switch delivers reliable high-current fault protection for switchgear applications. Maintenance teams struggle with large, bolted switches that complicate servicing and verification of safety interlocks. UL Listed certification ensures compliance with industrial safety standards, while its four NEMA enclosure ratings—NEMA 1, 3R, 4, and 12—support rugged installation in varied environments. In practice, this combination translates to fewer field miswiring incidents, faster commissioning, and long-term cost savings through fewer preventive maintenance events. For engineers and procurement teams, the unit offers compatibility with top-feed configurations and fault-detection options, reducing total ownership cost.

Eaton Specification Sheet - CB3033T120480GAR7
Feature → Business Impact → Application: High amperage rating of 3000A enables true fault protection for large switchgear assemblies, reducing the risk of catastrophic faults and downtime in heavy industry. This translates to measurable reliability improvements and lower incident-related costs during peak production periods in mining, metals, and chemical processing facilities. Application: Use in three-pole, top-fed control panels to simplify wiring and speed installation while maintaining robust protective coordination. Feature → Business Impact → Application: 120 V control voltage with 480 V system voltage supports seamless integration with common plant power architectures, minimizing control wiring complexity and enabling faster changeovers in there-to-here automation environments. Application: Suitable for NEMA 1, 3R, 4, 12 enclosures, delivering versatile installation in indoor and harsher environments. Feature → Business Impact → Application: 2 NO-2 NC contact configuration provides flexible signaling for both trip and alarm circuits, reducing the need for additional auxiliary devices and enabling more compact control schemes. Application: Ideal for applications requiring ground fault with optional protection and auxiliary provisions, such as data centers, food and beverage processing, and pharmaceutical manufacturing. Feature → Business Impact → Application: Fusible protection and top-feed configuration support straightforward maintenance planning and safer replacement workflows, lowering total cost of ownership even when part substitutions are necessary during scheduled downtimes. Application: Installation in top-fed, fusible-protected switchgear reduces risk during fuse changes and supports compliant maintenance procedures. Feature → Business Impact → Application: UL Listed certification and available catalog notes (ground fault relay, blown fuse detection, single phase protection, Kirk provisions, auxiliary contacts) provide confidence in regulatory compliance and expand protection schemes without costly retrofits. Application: Compliance-driven retrofit projects and new builds in regulated sectors benefit from readily configurable protection options and documented compatibility.

FAQs
Begin with confirming the 2 NO-2 NC contact configuration and top-feed fuse arrangement. Mount the unit in a suitably rated enclosure, connect the three power conductors to the load side, wire the control power to the 120 V control circuit, and verify ground fault provisions if required. Follow Eaton's installation notes for wiring torque, clearance, and safety interlocks to ensure compliant, reliable operation.
The switch provides a 3000A amperage rating, 480 V system voltage, and 120 V control voltage. It supports fusible protection and features a 2 NO-2 NC contact configuration, enabling flexible signaling for trips and auxiliary circuits while meeting typical industrial safety standards.
Yes. The unit is UL Listed and designed for NEMA ratings of 1, 3R, 4, and 12, supporting installation in indoor areas and more demanding environments. Optional features like ground fault relay and auxiliary provisions further enhance compatibility with protective schemes in diverse facilities.
The device consolidates protection functions in a single, heavy-duty unit, reducing field wiring complexity and commissioning time. With top-feed configuration and fusible protection, maintenance is streamlined, downtime is minimized, and the potential for miswiring decreases. Optional protections and auxiliary provisions enable tailored protection schemes, improving overall system reliability and ROI.
Catalog notes indicate options such as Ground Fault Relay, Blown Fuse Detection, Single Phase Protection, Kirk Provisions, and Auxiliary Contact Provisions. These features allow you to tailor protection to specific applications, enhancing safety, fault detection, and control coordination without requiring custom hardware.
