Eaton CB2533B120208RAX Bolted Pressure Switch - UL Listed
Part Number: CB2533B120208RAX
Quick Summary
CB2533B120208RAX by Eaton is a bolted pressure contact switch designed for high-current, single-phase protection in industrial switchgear. This solution addresses downtime and nuisance trips by delivering reliable capacitor-trip (SPVR) operation for controlled energization. UL Listed certification confirms safety and reliability, while the unit’s NEMA ratings support enclosure suitability from standard indoor panels to rugged outdoor environments (NEMA 1, 3R, 4, 12). In practice, it integrates with optional Ground Fault Relay, Blown Fuse Detection, and auxiliary provisions to match installation needs. For engineers and procurement teams, this enables safer power distribution and reduced maintenance costs in motor-control and process environments while supporting compliant, efficient operations.

FAQs
Plan for a three-wire, bottom-feed arrangement and verify the 208 V system with a 120 V control circuit. Connect each phase to the three poles, ensure fusible protection is configured, and integrate the capacitor trip device (SPVR) for proper sequencing. Use the optional auxiliary and grounding provisions as needed for your panel's protection scheme.
The device handles up to 2500A with a 120 V control voltage and 208 V system voltage, in a three-pole, three-wire configuration. It is fusible-protected and supports SPVR with a capacitor trip device, improving trip reliability and reducing nuisance trips in busy switchgear environments.
Ideal for high-current distribution in motor control centers (MCCs), power distribution panels, and industrial process lines. It aligns with 208 V infrastructure and is compatible with rugged enclosure standards (NEMA 1, 3R, 4, 12), making it suitable for indoor and outdoor installations in demanding environments.
The CB2533B120208RAX is UL Listed, providing essential safety certification for electrical protection devices. It also supports standard NEMA enclosure ratings, helping ensure enclosure compatibility and regulatory alignment in typical industrial installations.
This Eaton device carries a standard warranty per Eaton policy 25-000 (one year from installation or eighteen months from shipment, whichever occurs first). Benefits include reduced downtime from reliable SPVR operation, longer service life under high-current loads, and lower total cost of ownership in motor-control and distribution applications.
