Abstract (en)
[origin: EP1526560A2] The device has a main current path (10) in which a main contact point (13), a first thermal trip (12) and an armature system (16) for opening the contact point without the cooperation of a switch lock (25) are arranged. An electromagnetic trip is arranged in an auxiliary current path. The trip and the armature system have a common iron circuit, whereby the electromagnetic trip acts on the switch lock for on-going opening of at least one of the main contact points and has an arrangement for delaying tripping.
