KL8001 | Power terminal for Siemens contactor, series Sirius 3R

Like a standard motor protection relay the KL8001 power terminal is fitted to a power contactor up to a switching capacity of 5.5 kW. The connection mechanism of the KL8001 power terminal of the KL8xxx series is particularly suitable for Siemens contactors of the Sirius 3R series. Other power terminals are adapted for other contactor manufacturers. The power terminal switches the installed contactor and takes over all the functions of the motor protection relay. Apart from its purely protective function of switching off the motor when overloaded, the power terminal can carry out numerous diagnostic functions on the motor and make the information available to the controller via the fieldbus.
