Abstract (en)
[origin: WO2017029404A1] The present invention relates to a surge arrester (1, 21) for a domestic robot assembly including a perimetral wire (2) connectable to a control station (3), such as robotic lawn mower assembly. The surge arrester (1, 21) comprising a ground rod (4), a set of control station connectors (51, 52), a set of perimetral wire connectors (61, 62), and a protection circuit (7a) arranged between the set of control station connectors (51, 52) and the set of perimetral wire connectors (61, 62). The protection circuit (7a) comprising a first electrical path and second electrical path from the perimetral wire connector (61, 62) to the control station connectors (51, 52), and at least two surge protecting elements (75; 71, 72, 73) connected to and along each electrical path. Each surge protecting element (71, 72, 73) is further connected to the ground rod (4), such that the protection circuit (7a) is able to discharge at least a portion of a transient surge, entering from the set of perimetral wire connectors (61, 62), via the at least two surge protecting elements (75; 71, 72, 73) to the ground rod (4).
