WLCZ1 Series DC Electromagnetic Contactor

WLCZ1系列直流电磁接触器2

Product overview
WLCZ1-800 (formerly QCC31) type DC electromagnetic contactor is suitable for industrial and mining electric locomotives, subways, light rail vehicles and railway traction locomotives and passenger vehicles as a non-polarity switch, in the main circuit and auxiliary circuit for tap conversion contactor, unit control contactor.
WLCZ1-250 (formerly QCC35) type DC electromagnetic contactor is suitable for charging the main filter capacitor in front of the drive converter of rail vehicles, frequent operation of heavy load equipment such as mine traction and crane lifting (note that the specifications of the product for the polarity of the wiring mode).
A notable feature of this series of contactors is the modular structure, which is mainly composed of the following modules: contact unit, drive mechanism, arc extinguishing chamber, auxiliary contact, and housing.
The work of the contact system of the WLCZ1-800 type DC electromagnetic contactor is based on the principle of rolling contact. The moving contact in the contact unit is equipped with a spring, and has a rolling effect when it is closed, which has the effect of removing the oxide layer on the contact surface. The rolling contact makes the lower part of the contact conductive, and the upper part of the contact acts as an arcing contact. The arc extinguishing chamber is composed of a number of ionization gratings, which divide the arc into a series of short arcs, and then make the radon and radon and radon?

The contact unit of the WLCZ1-250 type DC electromagnetic contactor is designed as a direct-acting bridge type double breakpoint, which is directly driven by the solenoid electromagnet without lever transmission, reduces power loss, reduces the volume of the electromagnetic system, and has a compact structure. The arc-extinguishing cover adopts a fan-type structure, and two arc-blowing magnets ensure fast and effective arc-extinguishing. The standard form of auxiliary contact is two normally open and two normally closed.
