Eaton CB2033B120480KGPARC Bolted pressure switch - UL
Part Number: CB2033B120480KGPARC
Quick Summary
Eaton CB2033B120480KGPARC is a bolted pressure contact switch for high‑current switchgear protection. Engineers often face misoperation and downtime when protection relays fail or fault protection isn’t reliable. This unit carries UL Listed certification and is compatible with common NEMA enclosures (NEMA 1, 3R, 4, 12), with optional Ground Fault Relay and capacitor trip devices. In practice, you gain safer operation, easier maintenance, and faster troubleshooting, backed by a 25‑000 warranty. And the solution scales with your needs, using bottom‑fed, three‑pole, fusible protection for 480 V systems. This translates to reduced downtime during faults and a safer, more reliable power distribution network. Designed for engineers, procurement teams, and maintenance technicians, it aligns with standard Eaton accessories and field‑installable options.
