摘要:
A reset device (200) is described, which is associable with a safety electrical device of an electric circuit, which is suitable to adopt opened and closed states, comprising mechanical means (250) for transmitting to said safety device a reset motion from the opened to the closed state, and an actuating apparatus (260) for actuating the transmission means. The actuating apparatus (260) comprises an electromagnet (206) for generating a magnetic field and a moving element (208) mechanically coupled to the transmission means (250) and such as to be moved following to variations in said magnetic field to cause the reset of the safety device (100).
