摘要： A tripping device (1) for circuit breakers comprising a thermally influenceable wire-shaped tripping element (4) is presented, one end of which is attached to a rotatably supported tripping lever (3) which is under spring force and the other end of which is fixed in location. The thermally influenced lateral movement at one end of the tripping element (4) causes the unlatching of the circuit breaker. At the free end of the tripping lever (3), a locking element (11) is provided which engages a cam (10) of a contact lever (2) which is under spring force, in such a manner that the circuit breaker is switched off both with contraction and with expansion of the tripping element (4).

摘要： An electrical overload circuit breaker utilizes as the current-responsive tripping mechanism a solenoid, the coil of which is constituted by a helical spring of shape memory effect material and which mechanically acts on the armature. There is a non-SME spring which also acts on the armature but in a direction opposing the SME spring. The current is passed through the SME spring and, when it becomes excessive, the armature is urged both mechanically and electromagnetically in a tripping direction.

The switching element being in a vitreous-amorphous state and having a higher strength at a lower first temperature range, and in a crystalline state and having a lower strength at a higher second temperature range. A tensioning device cooperating with the switching element for exerting a force thereon which is sufficient to break the switching element in the crystalline state and insufficient to break the switching element in the vitreous amorphous state. A device for triggering a switching process in response to the breaking of the switching element in the vicinity of a transition from the first to the second temperature range. An exchangeable cassette assembly for housing the switching element, and a method for protecting circuits against overcurrents using the thermal switch.

The free end is provided with an upper electrical contact in alignment with a lower electrical contact of the first prong. An elastic member has a first straight abutment portion in resiliently abutment against a fixing element within the casing, a second straight that resiliently abuts against the free end of the alloy plate, whereby, the alloy plate is displaced from its initial position when an overload current flows through the switch in a switch-on position.
