SELECTIVELY ACTING THERMAL CIRCUIT BREAKER, METHOD FOR ITS RELEASE AND ITS USE FOR ELECTRICAL PROTECTION

摘要

1. Thermal switch with a selective action, possessing a switching element (18) which is made from an alloy having a shape-memorising capability and which is located, at least at a first point (15), in a manner essentially permitting free movement, and is rigidly attached to a body (16), characterised in that the mass (m) of this body (16) is adjustable and is assigned to a limiting acceleration-value (xG ) for triggering this thermal switch, it bein possible to preset this limitting acceleration-value.
