10 Description of parameter settings

10.1 Rotary switch in “CURRENT” position

The CONTACTRON Speed Starter features integrated full motor protection. The device

has an integrated tripping characteristic (see Figure 10-1). If the load of the motor is

higher than the nominal current, the device will trip according to this curve. Additionally,

the device has an integrated thermal memory. This means that in case of a high load, the

curve will be loaded up and leads to a faster tripping time. The tripping of the device is

dependent on the frequency. A low frequency leads to a quicker load of the thermal mem-

ory and a high frequency will react slower.
