Contactors typically have multiple contacts, and those contacts are usually (but not always) normally-open, so that power to the load is shut off when the coil is de-energized. Perhaps the most common industrial use for contactors is the control of electric motors.. Then connect the earth led wire to the motor body.

1 vs. 3 Phase Contactors. Every 3 phase contactor has 3 poles, one for each phase, while every single phase contactor has either 1 or 2 poles (please see "Switch Terminology: Pole Count" for more information).To explain the difference in the number of poles, we need to first review how AC. Compact size & easy connection. High Performance and long electrical life. Greater environmental immunity. Sealed structure which improves its safety features. Features Rated current : 6 ~ 800A with 6 Frame sizes Up to 440kW at 440V in category AC-3 Uimp = 8kV, Ui = 1,000V (over 40AF) Combination with Manual motor. That's why you need to understand the basics of contactors. When someone uses a lighting contactor in a motor application, that's a misapplication. The same is true when someone uses a "normal operation" motor contactor for motor jogging duty. Contactors.
Your air conditioner’s contactor and capacitor work together to help power your air conditioner’s fan and compressor whenever your thermostat calls for cool (the capacitor and contactor in your heat pump work the same way). The contactor is the “switch” that receives a low voltage (usually 24V) signal from your furnace to turn on. It. Siemens is an industry leader when it comes to contactors. Whether you're looking for the right contactor for motor starting purposes or for simple lighting applications, Siemens makes a reliable component for your application..
