2LP240 is a type of AC contactor, whose full name is two-pole AC contactor. It is widely used in some fields, such as divided machines, automation system, wind turbines, air conditioners, electric railway, general industrial equipment, etc. As an AC contactor, 2LP240 can be used for various kinds of electric equipments with A.C control circuit and rated control power. In this essay, we will introduce the application field and working principle of 2LP240.

Application field

2LP240 is suitable for rated power supply AC 50/60Hz, 220V, 380V or other types of power, as well as current up to 240A. This AC contactor is suitable for performing long-distance current operation, as well as making, breaking or change-over of electric current. It can apply to various electric devices, such as air-conditioner compressor, motor, electric saws, valves, air blower, etc. At the same time, it can also be used to divide the electric power supply when there is a power failure.

Working principle

2LP240 is a type of AC contactor, so it also works in the Electromagnetic operating principle. It consists of magnetic cores, coil, arc extinguishing chamber, armature, contact terminals, and outer shell. There are two separated sets of contacts in the 2LP240 contactor which can be opened or closed to control the power supply of a circuit. When a coil is energized, a magnetic field is generated at the core of the contactor and the armature is attracted to the core and moved towards it. Once the armature reaches the core, it will usually make contact with the contact terminals and the electric current is cut off. To keep the contactor engaged, the armature must remain in contact with the core and the contact terminals. When the current is cut off, the armature will be released from the core.

In conclusion, 2LP240 is a type of AC contactor which is widely used in various fields. It is suitable for performing long-distance current operation, as well as making, breaking or change-over of electric current. The working principle of it is based on the Electromagnetic operating principle, and it consists of magnetic cores, coil, arc extinguishing chamber, armature, contact terminals, and outer shell. By the application field and working principle, we can know more about the 2LP240 AC contactor.
