Eaton CB2033B120480RAXCT Bolted Pressure Switch - UL Listed
Part Number: CB2033B120480RAXCT
Quick Summary
CB2033B120480RAXCT bolted pressure switch is a single-phase relay for protection in industrial power systems. Engineers often deal with nuisance trips and incomplete fault detection, which this device mitigates with a capacitor trip and BFD. UL Listed safety certification anchors compliance, while its NEMA compatibility supports enclosure selection for harsh environments. In practice, this module delivers reliable protection at 480V systems with 2000A capacity and 120V control power. For procurement teams, the option set for ground fault relay, auxiliary contacts, and Kirk provisions adds value. The compact three-wire, three-pole design simplifies installation, reduces wiring errors, and supports future expansion. This content-rich spec supports informed purchasing decisions, pairing engineering detail with clear business outcomes.
