An electrical contactor is an electromechanical component for power control. It enables to open or to close a circuit before receiving an electrical signal. We can put it in open or closed position, to supply (or not) an electrical device.
An electrical contactor can be used for any application where a relay is not sufficient.
The contactor is placed in an electrical panel and has three commands which can be activated manually: automatic activation, stop, forced operation. It enables to stop or to supply an electrical device.
An electrical contactor is characterised by its breaking capacity (maximum contact intensity) and its control voltage (coil control voltage).
Standard control voltages are: 400 VAC, 220 VAC, 110 VAC, 48 VAC, 24 VAC, 24 VDC.
Several types of contactors exist depending on the application:
- Modular contactor HC20 for 220V tertiary application
- Three-pole contactor (for three-phases)
- Four-pole contactor (for 400V + neutral)
To install an electric contactor, you need:
- insulated screwdrivers,
- a flat screwdriver,
- wires,
- an electrical clamp and
- the contactor.
1. Secure the manipulation
Before starting the installation, it is important to cut the power from the main circuit breaker. It will ensure your security and enable to manage the electrical contactor by avoiding any risk of electrocution.
2. Installing the electrical contactor
The electrical contactor can be placed on the electrical panel directly. To do this, you first need to take off the box using a screwdriver.
The element should be placed next to the circuit breaker of the electrical equipment that it should control.
To connect the contactor, the busbars of the table row should be taken off by unscrewing all circuit breaker screws.
Then, you can clip all the elements on the rail of the row by sliding them against the others.
3. Wiring the contactor
The wiring must be made by following the diagrams supplied in our technical documentation on our website.
For wiring the electrical wires, to cut to the required dimensions, strip the end of the wires to put them in the contactor terminals. When using flexible wires, it is recommended to put end pieces.
4. Close the panel
You can now close the panel and turn the power back on to the main circuit breaker.
If you have questions or if you need information, please do not hesitate to call our team of technicians who can advise you and refer you if needed.
