Mains cables are used to connect pumps with single-phase motors. The PTC resistor tripping device evaluates the temperature-dependent resistance on pumps with three-phase motor. This increases the operational reliability, as impermissibly high temperatures are detected. The soft starter is required for operating the Duo 35/65 M. It limits the motor torque in order to protect the coupling against overload.
