Eaton CB2033T120480AR7 Bolted Pressure Switch - UL Listed
Part Number: CB2033T120480AR7
Quick Summary
CB2033T120480AR7 is a bolted pressure contact switch designed for high-current protection in industrial switchgear and motor control centers. Engineers often face downtime and mis-wiring risks when upgrading protection schemes, so a reliable trip device is essential. This UL Listed, three-pole switch supports 2NO-2NC contacts, 480 V system voltage, and 120 V control voltage, with top-feed and fusible protection options. The design emphasizes robust enclosure ratings (NEMA 1, 3R, 4, 12) and field-installable features to streamline maintenance. By combining strong protection with installation efficiency, it delivers both safety and cost savings for panel builders and plant operators. Secondary considerations such as optional ground fault relay and auxiliary provisions further enhance ongoing reliability and regulatory compliance.
