DC contactor FAQ's
A: Contactors and relays are electrically operated switches used for power control and load switching. Capable of handling up to 1,000 amperes, contactor switches power loads for motors, capacitors, lights — devices that drain very high current. Switching occurs via the energization and de-energization of the contactor coils. Contactors are chosen upon the ampere ratings of the load. Contactors require an additional supply (either AC or DC depending upon the type of contactor we use) for excitation.
On the other hand, relays are used for switching of control circuits. They cannot be used for power switching with high ampacity, as their maximum load is 20 ampheres. Given this limitation, they are most often used with switching of small lights, sirens, and indication lamps.
A: DC contactors are used for making and breaking an electrical power circuit, as in that within an electrical motor. Connecting a high voltage electric motor directly to a programmable logic controller (PLC) risks damage to the PLC cards should a power surge from the motor occur. The contactor’s low voltage coil produces a magnetic field, causing the contactor core to move the armature. When current is removed, the coil is de-energized and opens the circuit.
