Magnetic Relay Release
The magnetic relay Release is designed according to the principle of a holding magnet relay for use in residual current circuit breakers. The tripping system consists of plunger, pole and armature.
At delivery, the permanent magnet in the magnetic relay is fully magnetized and the armature is in the closed position , that is to say in contact with the pole.
The tripping power, respectively the tripping current, is set by demagnetizing the integrated permanent magnet after installation.
