FAQs
CB2033T120208RAX is designed for top-feed, three-pole configurations and weighs 180 lb. Plan for a two-person lift and confirm enclosure clearance, wiring access, and mounting feet fit within the 16 x 28 x 24 inch footprint. Ensure a UL Listed, NEMA-rated environment and use proper torque on connections per the Eaton spec sheet.
The capacitor trip device (SPVR) enables a controlled, charge-before-close sequence, reducing inrush-related stress and nuisance trips. Coupled with a BFD (blown fuse detection) option, it provides reliable protection without false trips, lowering maintenance costs and extending motor life in start-stop duty cycles typical of conveyors and pumps.
Yes. The switch is rated for a 208V system voltage with a 2000A amperage rating and 120V control voltage, making it suitable for heavy-duty three-pole motor circuits in industrial settings. Its NEMA 1, 3R, 4, 12 compatibility supports indoor and outdoor installations, ensuring dependable operation across harsh environments.
CB2033T120208RAX carries UL Listed certification and supports multiple enclosure ratings including NEMA 1, NEMA 3R, NEMA 4, and NEMA 12. This combination provides robust protection for harsh environments, while the top-feed, three-wire design simplifies integration with existing switchgear and minimizes wiring complexity.
The switch’s high current rating, reliable SPVR capacitor trip, and optional fault-detection features reduce downtime and maintenance frequency. With UL certification and durable construction, it supports longer service intervals and predictable lifecycle costs. Warranty terms (1 year installation or 18 months from shipment) further protect your investment.
