Eaton CB2533T120208CT Pressure Contact Switch - UL Listed
Part Number: CB2533T120208CT
Quick Summary
The Eaton CB2533T120208CT bolted pressure contact switch provides reliable, high‑current protection for motor circuits and power distribution panels. Designers often struggle to balance built‑in protection with space constraints and retrofit compatibility, and this model helps streamline panel builds without sacrificing safety. UL Listed certification and compatibility with demanding NEMA environments (NEMA 1, 3R, 4, 12) offer solid regulatory confidence, while options such as ground fault relay and auxiliary contacts support scalable protection schemes. With a built‑in control power transformer, the unit simplifies control wiring and reduces panel footprint. The result is improved uptime, easier commissioning, and a more robust solution for industrial switchgear and motor control centers.
