Abstract
The circuit arrangement for an auxiliary relay that actuates a starting relay for a starter device of an internal combustion engine includes a temperature measuring device (20) and a control and/or regulating circuit device (16,16') for controlling, in a turned-on state, an operating current (I) flowing through a relay coil of the auxiliary relay according to a temperature of the auxiliary relay or starting relay measured by the temperature measuring device (20) so that the operating current (I) and mean value of the operating current (I) are controlled according to the temperature. The control and/or regulating circuit clocks the operating current and can vary the duty cycle to reduce the power losses.
