  • What size contactor should the capacitor be matched with

    What size contactor should the capacitor be matched with

    The first item to consider is the load, measured in amperes. This load amperage is the amount of current required to power your device at the line voltage. It is important to know this at the line voltage you intend to use because the current will change with the voltage according to P=IV (sometimes referred to as P=VA), where. Next, you should confirm the control voltage to power the contactor. This can be the same as the line voltage, however often a lower voltage is selected for the contactor for safety purposes. Generally, coil voltages are 250V or. IEC uses utilization categories, or “codes,” to describe the type of electrical load and duty cycle of the load(s) specifically. This is important because. Auxiliary contacts allow additional operations to take place when the contactor is energized. Multiple auxiliary contacts can be added in. Another consideration is whether the motor operation requires reversing of the direction, in which case a reversing contactor would be.

    How does capacitance affect the discharge process?

    C affects the discharging process in that the greater the capacitance, the more charge a capacitor can hold, thus, the longer it takes to discharge, which leads to a greater voltage, V C. Conversely, a smaller capacitance value leads to a quicker discharge, since the capacitor can't hold as much charge, and thus, the lower V C at the end.
