Abstract (en)

[origin: EP2254138A2] The breaker has a strip sheet (2) composed of thermal double metal or shape memory alloy, where a fixing end (3) of the sheet is fixed to a U-shaped bump (31) of an electric arc control bus (12). The bump is provided with two side legs (4, 32) and a bending part (5). The bending part and one of the side legs (4) are provided with a groove, so that the side leg is divided into a support (41) and a contact arm (42) that is connected with a terminal line (29) of a wire connecting terminal (9). The strip sheet is fixed to a free end of the support arm. An independent claim is also included for an electricity switch equipment comprising a current circuit.
