Q:How to use Star Triangle to start contactor orders and processes
Coil circuit in the KMY contactor Contact, when the KMY moving contact is closed, KMY moving contact is broken, after a pre-set delay, the time relay dynamic contact KT off, cut off the coil KMY, the circui
Q:Research on Relay Parameter Detection Technology Based on Single Chip
Similarly, the release time of the relay can be obtained. At the same time the test device can also monitor the contact resistance of the contacts.
Q:What about the number of AC contactors?
so that the main contact is disconnected and the auxiliary normally closed contact which is mechanically connected with the main contact is closed
Q:Traditional communication contactor long life and long reliability?
Contactor life and reliability are primarily determined by coil and contact life. Traditional AC contactor because of its work when the coil and the core will be hot,
Q:AC contactor technology development
Vacuum contactor: Vacuum contactor is the contact system using vacuum degaussing chamber contactor.
Q:What is the noise-free function of traditional contactors?
there will be noise. While the permanent magnet AC contactor is held by the permanent magnet force to maintain, so there will be no noise generated.
Q:What parts of the contactor
No matter what extent the development of technology, ordinary AC contactor still has its important position.
Q:What is the role of the contactor
Can be frequently connected with the high current control (up to 800A) circuit device, so often used in the motor as a control object, can also be used to control the plant
Q:Similar terms for contactors and relays
The main function of the main circuit is to connect to or disconnect the main circuit. The so-called main circuit is a circuit is working or not by the circuit is connected to the mark.
Q:The contactor is mainly composed
The service life of the contactor is very high, the mechanical life is usually several million to ten million times, and the electrical life is generally several hundred thousand to several million times.
