EN 60947-2 Low Voltage Switchgear and Controller, Part 2: Standard Test for Circuit Breakers

EUROLAB laboratory provides testing and compliance services within the scope of EN 60947-2 standard. EN 60947-2 applies to circuit breakers whose main contacts are intended to be connected to circuits, with a rated voltage not exceeding 1000 V ac or 1500 V dc; it also includes additional requirements for circuit breakers with integrated fuses.

The rated currents of circuit breakers apply regardless of the method of construction or recommended application. Requirements for circuit breakers designed for use by untrained persons for the protection of wiring in buildings and similar applications are contained in IEC 60898.

The rated short-circuiting capacity of a circuit-breaker is the value of the short-circuiting capacity assigned to that circuit-breaker by the manufacturer for the rated operating voltage at a given power factor or time constant at the rated frequency. Expressed as Maximum possible peak current for DC.

A rated short-circuit making capacity means that the circuit breaker must be capable of making the current corresponding to that rated capacity at the appropriate applied voltage relative to the rated operating voltage.
