Abstract (en)
[origin: EP0773571A1] The FI-switch release has a housing with a pin Ä4Ü that is displaced axially to operate contacts to operate an isolating switch. The actuator has an armature Ä8Ü that is supported on leaf spring element Ä5Ü and is normally in a position where the armature sits against pole surfaces Ä30Ü in a plate . On the underside of the plate is a yoke Ä16 and permanent magnets Ä17Ü, together with a coil Ä10Ü. When the coil current is sufficient a magnetic field is generated and the armature responds to displace the pin.
