Capacitor On Contactor Coil at Brooke Harper blog

Capacitor On Contactor Coil. I have a 24 vac contactor that i want to drive with a microcontroller through a photmos. If i'm understanding correctly, upon startup, the resistor/thermistor will suppress the capacitor inrush and slowly charge it (charge time depending on resistance. In some cases a device called a snubber is connected across the coil , which a snubber consists of a capacitor and a resistor. The cable capacitance is across the switch contacts, and the additional capacitor is across the contactor. How do i calculate the proper size resistor and capacitor for a snubber circuit? The purpose of d2 and d4 is to absorb inductive spikes from the coils. When the contactor opens, the metal core that is used to pull in the contactor in will create a quick induce voltage in the coil as the.
