What is a Contactor Exactly, & How Does It Work?
A magnetic motor contactor functions as a mediator between a high-load electrical motors and its direct power source. These contactors are essentially a sort of electrically-controlled switch. They are somewhat similar to a circuit breaker in terms of design, but they offer some very specific applications in terms of the functionality of the motor in question. Like a circuit breaker, contactors can act as a sort of safeguard and help to balance any variations or changes in electrical frequency which flow from the power supply. A magnetic contactor works in tandem with an overload relay to help operate a magnetic starter safely and effectively. Another unique feature of many contactors is that they can be detached from a motor for the purposes of disassembly or other regular maintenance procedures.
What Can Lead to a Faulty Contactor?
Like any other piece of sensitive electronic equipment, issues can develop with a contactor over time that will eventually need to be addressed. Once the electrical contacts start to wear down, any contactor can fail. Possible threats to connectors include moisture, acidic fluids, and even air. Contactor connections which rub together on a regular basis can also develop worn surfaces, which will impede the contactor’s ability to conduct electricity properly. This can result in some incredibly hot arcs which end up melting cable insulation, and can ultimately produce in a short circuit in the system.
Testing the Contactors
Depending upon the location of your contactor, along with your personal level of comfort in handling electronic equipment of this nature, you may be able to do some simple testing and troubleshooting of your contactor on your own. Here are a few steps you can try:
- Remove electrical power, and pull the wires from the line-side screws. Identify and label each individual wire.
- Remove the terminal side wires, and also identify and label each wire properly.
Energize the contactor’s coil, and then test each set of L1-to-T1 contacts with an ohmmeter. Each set should read 0 ohms; if it doesn’t, then that set can be presumed to be bad, and should be replaced.
- Follow a similar procedure to test each set of contacts for voltage with a voltage meter. The meter should display in accordance with the supplied voltage to the circuit.
- If this all looks good, but the coil still doesn’t close, then shut off power to the coil. * * * Remove the coil wires, and then use the ohmmeter to check each coil connector. The meter should read between 10-100 ohms. If it doesn’t, then the coil itself is probably bad, and needs to be replaced.
