What is LC1D?
The LC1D is the most popular in the range and is used to start the 3-phase AC motor. Well known for its long life and the standard for both Coordination Type I and II. The contactor LC1D can be used with thermal overload relay LRD series for the Direct Online application.
What are magnetic contactors?
Magnetic contactors are the same as the electrical relays which are used in a number of electric motors. Magnetic contactors are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from ON and OFF state.
Why do we use contactors?
A contactor is an electrical device which is used for switching an electrical circuit on or off. These contacts are in most cases normally open and provide operating power to the load when the contactor coil is energized. Contactors are most commonly used for controlling electric motors.
What are two basic types of contactors?
There are different types of contacts in a contactor, and they are; auxiliary contact, power contact, and contact spring. The power contact has two types that are; stationary and movable contact. Material for making contacts must have a high welding resistance and stable arc resistance.
What is the difference between a contactor and a solenoid?
A primary advantage of solenoids is their ability to use a low input to generate a larger output via the coil, thus reducing strain on the battery. The contactor is the relay to use when a circuit must support an even heavier current load (typically 100-600 amps).
What is the difference between a contactor and a breaker?
An electronic contactor is a simple switching device, whereas the circuit breaker is a protective system. The primary function of a contactor is controlling the power. A circuit breaker does the protecting. Contactor works under normal situations.
What are the types of contactors?
What is a contactor relay used for?
A Relay is similar to a Auxiliary contactor,which is used in generally control circuit,specially in PLC for as a Digital input(feedback) or as a Digital out put to Switch on or off a electrical Contactor. we can also used a relay in place of a auxiliary contactor. relays are always used in a low current carring circuits.
What is inside contactor?
A contactor is a small device that controls the flow of electricity to one of your air conditioner’s components. You can think of a contactor like a drawbridge that extends over a river. When the drawbridge is down, cars can drive freely over the bridge to get to the other side.
What is contactor on AC unit?
A contactor is an electrical relay that controls the flow of electricity to components in the AC unit. The contactor sends voltage to the condenser and outdoor fan motor. Voltage from the thermostat is sent to the contactor and is registered by the contactor’s side terminals.
What is an electrical contactor for?
A contactor is an electrically-controlled switch used for switching an electrical power circuit. A contactor is typically controlled by a circuit, which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
