A suppression choke as an overload protection for electric motors according to the prior art is divided in two at a connecting point, which is intended to break in the event of an overload. This produces an additional connecting point by means of soldering. The mechanical stress on the connecting point to be broken often cannot assure a breaking of the connecting point due to the insufficient mechanical initial stress of the windings of the choke. In an overload protection for electric motors according to the invention, including a one-piece suppression choke (1), the connecting point (15) to be broken is produced by means of at least one connecting point (15) between the connection lug (11, 13) and a respective connecting element (5, 6) of the suppression choke (1), wherein the connection lug (11, 13) exerts an adjustable mechanical stress on the connecting point (15), thus reliably assuring a break when the softening temperature of the solder of the breaking point (15) is reached. |
