Quick Summary

Introducing the Eaton pringle bolted pressure contact switch, a high-capacity protective device for industrial power distribution. Engineers often contend with nuisance trips, ground-fault concerns, and the challenge of coordinating top-feed, three-pole protection in demanding facilities. UL Listed certification ensures safety compliance, while the enclosure support is validated by NEMA ratings 1, 3R, 4, and 12 for harsh environments. Optional Ground Fault Relay, Blown Fuse Detection, and Auxiliary Contact Provisions can be selected to tailor protection without unit redesign. With 4000A capacity at 480V and 120V control circuitry, the unit streamlines procurement and maintenance, delivering reliable protection and straightforward integration with existing switchgear.

FAQs

CB4033T120480RARCT is designed for top-feed, three-pole protection in 480 V systems. When integrating with existing Eaton gear, verify compatible bus connectors, matching control voltages (120 V), and space for a 17 in x 28 in x 40 in footprint. Ensure SPVR and optional ground fault components are wired per Eaton datasheets and factory recommendations to maintain coordination and maintainability.
The SPVR (Single-Phase Voltage Relay with Capacitor Trip) uses a capacitive trip circuit to provide a fast, predictable trip signal during fault conditions. In CB4033T120480RARCT, this feature improves single-phase protection coordination, reduces nuisance trips, and works in concert with the three-pole architecture and 480 V system voltage to protect downstream equipment.
Yes. The unit is specified for 480 V system voltage with a three-pole, three-wire configuration and fusible protection. It supports high-current applications up to 4000 A and is designed for industrial switchgear environments, providing robust protection and compatible control voltage at 120 V.
CB4033T120480RARCT is UL Listed for safety compliance and carries multiple NEMA enclosure ratings: 1, 3R, 4, and 12. These ratings indicate suitability for general indoors, outdoor weather-protected, splash-prone, and rugged industrial environments, respectively, helping meet diverse regulatory and facility requirements.
The combination of a 4000 A amperage rating, SPVR protection, and optional features like Ground Fault Relay and Blown Fuse Detection reduces unplanned downtime by improving fault visibility and coordination. Its compatibility with standard 120 V control circuits simplifies service, lowers spare-part costs, and accelerates maintenance, contributing to lower total cost of ownership.
