    150A High Voltage DC Contactor Details

    Tips: Magnetic blowing device working principle of a DC concactor

    When the contactor’s movable and static contacts disconnect, arc will generate between the contacts, the arc still maintains the load current within a short period of time. At this moment, two magnetic fields will generate before the arc extinguishes. One magnetic field is formed by the current around the arc, of which the direction can be determined by the Ampere's rule. Moreover, there’s still another magnetic field around the arc, which is produced between two magnetic splints by the current when it flows the blowout coils. This magnetic field passes the iron core and goes through one magnetic splint, it enters another magnetic splint through the gap and forms a closed magnetic circuit.
    Obviously, above the arc, the magnetic field between two magnetic splints has an opposite direction with that of the magnetic field around the arc, the magnetic field intensity is also weaker. Below the arc, the two the magnetic fields have same direction and the field intensity strengthens. Therefore, the arc will be pulled from the strong side of the magnetic field to the weak side, it moves upwards. In this process, the arc will be quickly elongated and form a relative motion with the air, thus reducing the arc temperature. Meanwhile, when the arc is blown to the upper part of arc chute, the heat of the arc will be transferred to the arc chute, thus further reducing the arc temperature, promoting the rapid extinction of the arc.

    Yes, this contactor ATO-ADH150 has a maximum coil current of 2A at the moment of startup.
    Do you provide 150A high voltage DC contactor with N/C auxiliary?
    Do you provide high voltage DC contactor 120v of model: ATO-DCCON-HV150 with N/C auxiliary? If yes, what is the price includes Shipping To Netherlands?

    Unfortunately don't provide NC auxiliary for 120VDC, but can provide for up to 80VDC operating voltage (low voltage DC conatctor).
