Abstract (en)

[origin: EP0020311A1] The present invention is related to a trip lamina employable for single-pole circuit breaker. The trip lamina (6) has an adequate thickness and is rendered very flexible because it is provided with shearings (13) interesting its whole thickness and that are transversal to the longitudinal direction of the lamina itself, said shearings having their respective outlets alternatively on both the longitudinal edges of the trip lamina, the latter being provided with successive holes (14) having at least one side (15) directed transversely to the longitudinal direction and prolonged by a respective shearing (13), said shearings being so finely executed that their edges (13 min -13 sec ) meet and rest one on top of the other to render said trip lamina resistant to the bending and compressive stress transmitted by the tip (5) of the latching cradle (4) of the circuit breaker.
