    摘要: A thermal tripping mechanism of a surge protection device comprises an elastic mechanism. Two first protection components (103) and one second protection component (108) form a Y-shaped layout and the two first protection components (103) are directly or indirectly connected to the second protection component (108) by using a thermal fusing material. The elastic mechanism comprises an elastic part (105) and a slide part (106). The elastic part (105) drives the slide part (106) to move by an elastic force. When the two first protection components (103) are both in a normal working state, the thermal fusing material does not reach a fusing temperature, the two first protection components (103) and the second protection component (108) form a conductive path, and the elastic part (105) is in an energy storage state. When at least one of the first protection components (103) is in an abnormal working state, the thermal fusing material reaches the fusing temperature and is fused, the elastic part (105) releases energy for driving the slide part (106) to move, and the slide part (106) moves to cut off the conductive path.

    摘要: The invention relates to a circuit breaker (100) for protecting an electrical system (10). The circuit breaker comprises a semiconductor switching element (T1) with a first (1) and a second (2) electrical terminal connected to a mains supply line (LIN) and a control terminal (3). Such switching element (T1) is controlled by enabling/disabling a control signal (S) applied to the control terminal (3) for switching between an open/closed status and a closed/open status for connecting/disconnecting at least one load (LD) to/from the supply line (LIN). Moreover, the circuit breaker comprises a drive (DV) adapted to enable/disable the control signal (S).
    The circuit breaker (100) is characterised in that it comprises:
    - a current limiting circuit (200) operatively associated with the mains supply line (LIN) configured for sending a first signal (S1) to the drive (DV) for disabling the control signal (S) switching the switching element (T1) from the closed status to the open status subsequent to the detection of a current value (Icc) indicative of a failure in the system;
    - a voltage regulator circuit (300, 400) connected to the first (1) and to the second (2) electrical terminal, comprising:
    dissipation means (300) of an electrical energy stored on the mains supply line (LIN) subsequent to the switching of the switching element (T1) from the closed status to the open status,
    means (400) for limiting a failure voltage between the first (1) and the second (2) terminal generated by peak values of the failure current (Icc).


    Moreover, the circuit breaker comprises an overheating safety circuit of said first (1) and second (2) electrical terminal caused by a non conforming clamping of the electrical wires connected to such terminals.

    摘要: The invention relates to a switching unit (1) for switching high DC voltages, in particular for a galvanic DC interruption between a DC source (2) and an electrical device (3). The switching unit (1) comprises two connections (11, 12), which protrude out of a housing (10) and are coupled electrically conductively via a conductor path (22), a contact system (7) arranged between the first and the second connection (11, 12) and a disconnecting apparatus (27, 27') which can be triggered by means of a thermal fuse (8). The thermal fuse (8) comprises a fusing point (19) arranged in the conductor path (22), said fusing point being connected firstly to the contact system (7) and secondly to the first connection (12), via a movable conductor section (20). The disconnecting apparatus (27, 27') is triggered and the connection between the conductor section (20) and the contact system (7) at the fusing point (19) is disconnected when, as a result of an arc (26) produced when the contact system (7) opens, the fusing temperature of the fusing point (19) is reached or is exceeded.
