Contactors for Capacitor Switching(UA 16 to UA 110) Maximum permissible peak current Î< 100 times the nominal rms current of the switched capacitor. A... and AF... Standard Contactors(A 12 to A 300 and AF 50 to AF 750) Maximum permissible peak current Î < 30 times the nominal rms current of the switched capacitor. Contactors for Capacitor Switching
AC contactors are used in air conditioning units to switch current from the compressor to the fan motor inside the home. When the thermostat calls for cool air, the contactor closes the circuit, allowing current to flow from the compressor to the fan motor.
Application The A...and AF...contactors are suited for capacitor bank switching for the peak current and power values in the table below. The capacitors must be discharged (maximum residual voltage at terminals < 50 V)before being re-energized when the contactors are making.
Primarily, understanding the selection codes of the capacitor switching contactors; to start with is the range name, HDC19s, which is followed by the numerical denoting the frame current varying from 25A to 175A. Next to the sequence, we have the list of auxiliary contacts based on the number of NO and NC contacts.
A capacitor stores power in a roll of electrically charged sheets of material. In other words, the capacitor has enough voltage to power the compressor and fan motors. That also means it has enough voltage to shock the hell out of you! The contactor on your AC unit is like a switch located in the AC system’s outdoor condenser unit.
AC-1: Such duty contactors are used in resistive loads such as heaters and electrical furnace. Non-inductive or slightly inductive loads are included which means the power factor of the load lie between 0.95 to 1. AC-2: These are used in slip-ring motors starters such as Switching on and switching off the motor.
