Quick Summary

Eaton CB2033B120208GRA bolted pressure contact switch is designed to provide single-phase protection for low-voltage motor circuits in industrial equipment. Maintenance downtime and nuisance trips are common pain points, but this unit uses a capacitor trip device (SPVR) and ground-fault features to improve reliability and reduce unplanned shutdowns. The device is UL Listed and compatible with a broad range of enclosures (NEMA 1, 3R, 4, 12), supporting safe, compliant operation in harsh environments. Its bottom-feed, three-pole design simplifies installation in existing panels, while fusible protection enhances system safety. Optional Ground Fault Relay and Auxiliary Contact provisions offer scalable protection for growing automation needs.

FAQs

Install the CB2033B120208GRA with bottom feed wiring in a compatible three-pole, 208V distribution panel or motor control center. Ensure proper clearance for 16 in depth panels and secure grounding. Use the optional ground fault relay or auxiliary contacts only if your protection scheme requires additional isolation or signaling.
The device is rated for 2000A with a 120 V control voltage and 208 V system voltage, configured as a three-pole, three-wire, fusible switch. It employs a capacitor trip device (SPVR) for single-phase protection and supports ground fault detection, providing robust protection for critical loads.
Yes. Catalog notes indicate optional Ground Fault Relay and Auxiliary Contact Provisions are available, enabling scalable protection and signaling without replacing the core switch unit. This is advantageous for evolving automation and safety requirements in plant infrastructure.
The CB2033B120208GRA is UL Listed, ensuring recognized safety certification. It also supports enclosure compatibility up to NEMA 1, 3R, 4, 12, enabling use across diverse environmental conditions and panel types.
Expected maintenance is minimized by a touchpoints approach: reliable SPVR operation, fusible protection, and optional fault detection reduce downtime and spare parts needs. ROI improves through fewer nuisance trips, extended equipment life, and easier retrofits within existing switchgear without extensive rewiring.
