© Siemens AG 2009 Motor starter protector/circuit breaker + contactor + 3RB20/3RB21 solid-state overload relay CLASS 20, types of coordination 2 and 1, short-circuit breaking capacity I q = 50 kA 400 V AC 1) Guide value for 4-pole standard motors for 400 V AC, 50 Hz. Selection de- pends on the concrete startup and rated data of the protected motor. 2) The motor starter protector/circuit breaker is to be set to maximum current value. 3) Rated control supply voltage 230 V AC, 50 Hz. Other control voltages are also possible.
