Example Embodiment
[0029] Such as Figure 1-Figure 3 The magnetic holding DC contactor shown includes a housing, and three sets of contact-electromagnetic units arranged in the housing. The contact-electromagnetic unit includes a contact system and controls the disconnection of the contact system. Open and closed electromagnetic system.
[0030] In this embodiment, the contact system includes a static contact system and a moving contact system, the static contact system includes two static contact assemblies arranged vertically opposite each other, the moving contact system includes a moving iron core, and The moving contact assembly is connected to the moving iron core as a whole. The moving contact assembly is located between the static contact assemblies. When the moving iron core moves back and forth, the moving contact 152 on the moving contact assembly is connected to the upper side Or the static contact on the static contact assembly on the lower side is turned on.
[0031] The electromagnet...
