3RV Motor Starter Protectors/Circuit Breakers up to 100 A General data Limiter function with standard devices for 500 V AC and 690 V AC acc. to IEC 60947-2 The motor starter protector which is connected downstream must be set to the rated current of the load. The table shows the rated ultimate short-circuit breaking capa- city I cu and the rated service short-circuit breaking capacity I cs with an upstream standard motor starter protector that fulfills the limiter function at 500 V AC and 690 V AC. The short-circuit brea- king capacity can be increased significantly with an upstream standard motor starter protector.
With motor starter protector combination assemblies, note the clearance to grounded parts and between the motor starter pro- tectors. Short-circuit resistant wiring between the motor starter protectors must be ensured. The motor starter protectors can be mounted side by side in a modular arrangement. ° No back-up fuse required, since short-circuit resistant up to 100 kA Short-circuit resistant up to 100 kA 1) 10 % overvoltage. 2) 5 % overvoltage.
