Quick Summary

Eaton CB4033B120480GRAX7 is a bolted pressure contact switch used for three-pole protection in industrial power circuits. Maintenance teams often battle nuisance trips and slow fault clearance that disrupt uptime and raise maintenance costs. This device carries UL Listed certification and broad NEMA ratings (NEMA 1, 3R, 4, 12), supporting enclosure versatility and harsh-environment reliability. The combination of a fusible protection option and a capacitor trip device (SPVR) helps meet demanding protection schemes while minimizing downtime. Value is further realized through compatibility with Eaton switching devices catalogs, standard installation with bottom feed, and a one-year warranty, delivering lower total cost of ownership in high-demand industrial spaces.

FAQs

For best results, plan for bottom feed wiring and compatible terminal blocks, route control wiring separately from power conductors, and verify enclosure clearance for a three-pole assembly. Ensure Kirk Provisions or auxiliary contact provisions are accommodated if your control scheme requires signaling or remote monitoring. Verify UL Listed compliance and field-verified wiring practices to minimize startup incidents.
Key ratings include a 4000A amperage rating, 480V system voltage, and 120V control voltage, with a 2NO-2NC contact configuration. Protection is Fusible with optional ground fault relay and SPVR capacitor trip device. It supports NEMA 1, 3R, 4, and 12 enclosures, enhancing reliability across varied environments.
Yes. The catalog notes explicitly mention optional Ground Fault Relay and SPVR capacitor trip device support. These features enable selective tripping and enhanced fault protection, especially in facilities with sensitive equipment or stringent safety requirements.
It supports broad NEMA ratings including NEMA 1, NEMA 3R, NEMA 4, and NEMA 12, enabling use in cabinet and open-enclosure environments. UL Listed certification confirms compliance with industry safety standards, and the bottom-feed, fusible configuration simplifies integration into existing switchgear or panel boards.
The CB4033B120480GRAX7 consolidates high-current protection in a single device, reducing equipment count and downtime. Its SPVR option and optional ground fault relay improve safety and fault selectivity, lowering unscheduled outages. A standard one-year warranty from Eaton adds protection against early failures, contributing to a favorable total cost of ownership for plant upgrades and ongoing maintenance programs.
