Eaton CB2033T12048056 pressure contact switch - UL Listed
Part Number: CB2033T12048056
Quick Summary
CB2033T12048056 is a pringle bolted pressure contact switch designed for high-current protection in industrial power distributions. Operators often struggle with reliable fault protection and trips in top-fed switchgear, especially at 480 V and 2000 A. UL Listed certification ensures safety compliance, while its broad NEMA ratings accommodate both indoor and harsh enclosure environments (NEMA 1, 3R, 4, 12); fusible protection supports safe, defined isolation. Its top-feed, three-pole design pairs with standard 120 V control circuits and 480 V power, delivering robust performance in panelboards, switchgear, and heavy-duty electrical rooms. This combination lowers downtime and simplifies maintenance plans for OEMs and service teams.

FAQs
Ensure power is off, mount in a suitable enclosure, connect conductors to the top-fed terminals, wire the 1 NO-1 NC contacts per the wiring diagram, and tie in the 120 V control circuit for reliable operation. Confirm enclosure ratings match the NEMA 1, 3R, 4, 12 requirements and verify fusible protection is correctly sized for your 480 V system.
It is rated for 2000 A with a 480 V system voltage and a 120 V control voltage. The device supports NEMA 1, 3R, 4, and 12 enclosures and uses fusible protection for safe isolation during faults.
Yes. The three-pole, top-feed, 1 NO-1 NC configuration is designed for high-current protection in switchgear, panelboards, and distribution cabinets, offering reliable isolation and coordinated control in industrial environments.
The device is UL Listed, with enclosure compatibility across multiple NEMA ratings, and supports fusible protection. Optional features like ground fault and auxiliary provisions further enhance regulatory compliance and protective capability.
Warranty follows Eaton policy 25-000: one year from installation or 18 months from shipment, whichever comes first. For maintenance, plan regular inspections of fuse status, control wiring, and any optional protective accessories (ground fault relay, auxiliary contacts) to sustain reliability.
