Specifies requirements for circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1000 V a.c. or 1500 V d.c. Includes requirements for coordination under short-circuit conditions between a circuit-breaker and another short-circuit protective device. Is identical with and has been reproduced from IEC 60947.2 Edition 3-0 (2003-04).
