CN35BN2 - Cutler-Hammer Contactor

CN35BN2 - Cutler-Hammer Contactor

The CN35BN2 Eaton CN35 contactor is a 20 Amp, 3-pole motor control contactor used in everyday industrial and commercial control setups where motors need to be switched on and off through a control circuit. You’ll usually find this kind of contactor in HVAC equipment, pump systems, small machinery, and general motor control panels, where dependable switching is part of normal day-to-day operation.

It runs on a 120V AC coil, which is standard in many control circuits. With its 3-pole, 20-amp configuration, it handles typical motor switching for three-phase applications or other control configurations depending on how the system is wired. In practical use, it’s not complicated — it’s just a familiar, reliable piece that electricians install when they need something that fits into an existing CN35 system without extra adjustments.

At the end of the day, this contactor is used where consistency matters more than anything else — same footprint, same function, same straightforward operation in CN35-based control systems.
