Various types of contactors are classified
connected to the circuit. In the above process, the coil itself has resistance, the continued consumption of electricity
the solenoid coil has been energized work, resulting in electromagnetic suction, to ensure that the core and armature pull, with moving, static contact Closed
DC contactor as a widely used one of the electrical switch, the production and the demand for a huge number, in the normal use of the process
This non-contact power electronic switch circuit does not produce arc, which avoids the traditional contactor arc on the contact material of electrical wear, it greatly increases the contact life and reliability
his hybrid contactor uses the traditional DC contactor in the closed conduction state contact contact resistance is small, the conduction pressure drop is small, will be anti-parallel thyristor and control module unit composed of non-contact switch in parallel with the traditional DC Contactor contacts.
