摘要:
The invention relates to an electromagnetic relay with an electromagnetic coil for exciting a magnetic field and an iron circuit for guiding the magnetic field, wherein the electromagnetic coil surrounds at least part of the iron circuit and the iron circuit comprises a core, a movable armature and a yoke. The electromagnetic relay further comprises a contact system with a movable contact bridge which can be actuated dependent on the magnetic field. In order to provide an electromagnetic relay that is able to disconnect or connect a plurality of electric contacts simultaneously in a particularly secure and loss reduced manner, according to the present invention there are provided at least three electric contacts on the contact bridge. According to an advantageous embodiment, the contact system comprises three fixed contacts which are corresponding each to one of three phases and the contact bridge forms a star point of the three phases.
