3RV Motor Starter Protectors/Circuit Breakers up to 100 A General data Technical specifications This table shows the rated ultimate short-circuit breaking capacity I cu and the rated service short-circuit breaking capacity I cs of the 3RV1 motor starter protectors with different inception voltages dependent of the rated current I n of the motor starter protectors. Short-circuit breaking capacity I cu , I cs acc. to IEC 60947-2 motor starter protector with a limiter function can be connected upstream. The maximum rated current for the back-up fuse is specified in the tables. The rated ultimate short-circuit breaking capacity then applies as specified on the fuse.
Motor starter protector infeed is permissible at the upper or lower terminals without restricting the rated data. If the short-cir- cuit current at the place of installation exceeds the rated short- circuit breaking capacity of the motor starter protector as speci- fied in the table, a back-up fuse is required. Alternatively, a Fuseless construction Motor starter protector contactor combinations for short-circuit currents up to 50 kA can be ordered in the form of fuseless load feeders according to Chapter 6. ° No back-up fuse required, since short-circuit resistant up to 100 kA 1) 10 % overvoltage. 2) 5 % overvoltage.
4) Alternatively, fuseless limiter combinations for 690 V AC can also be used. 5) The values for the 3RV17 42 circuit breakers have been tested only up to 400 V/415 V AC; values > 440 V AC on request. 3) Back-up fuse only required if the short-circuit current at the place of installation > I cu . 13 Siemens · 2009 Motor starter protectors/circuit breakers Type Rated current In Up to 240 V AC1) Up to 400 V1)/415 V AC2) Up to 440 V1)/460 V AC2) Up to 500 V1)/525 V AC2) Up to 690 V AC1) (these values do not apply to 3RV17 42 circuit breakers) Icu Ics Max. fuse (gL/gG) Icu Ics Max. fuse (gL/gG)3) Icu Ics Max. fuse (gL/gG)3) Icu Ics Max. fuse (gL/gG)3) Icu Ics Max.
