Description | 1. A contactor is an electrical device that is widely used for switching circuits on and off. |
2. Contactors are principally designed for use in applications where a large amount of current needs to be switched. | |
3. A contactor is an electrically controlled switching device, designed for repeatedly opening and closing a circuit. | |
Application | 1. An electrical contactor is used in a wide range of situations where there is a need to switch power to a circuit repeatedly. |
2. Contactors are mainly chosen for higher power applications than relays. | |
3. Typically, a contactor will be used in situations where power loads need to be turned on and off frequently or rapidly. | |
4. Contactors being used to control high-power lighting installations will often be arranged in a latching configuration, to lower overall power consumption. | |
When the electromagnetic coil has a current passed through it, a magnetic field is created. This causes the armature within the contactor to move in a certain way regarding the electrical contacts. |
