Rated making capacity DIN EN 60947-1; 4.3.5.2
The current that a switching device can make in compliance with the utilisation category at
the respective rated operating voltage.
➜ Rated operating voltage
Rated frequency DIN EN 60947-1; 4.3.3
The frequency for which a switching device is designed and on which the other characteristic
data is based.
➜ Rated operating voltage; Rated uninterrupted current
Rated ultimate short-circuit breaking capacity (I
The maximum short-circuit current that a circuit-breaker is capable of breaking (test O - CO,
previously P - 1). After short-circuit breaking, the circuit-breaker is capable of tripping under
an overload, with increased tolerances.
Rated insulation voltage (U
Voltage to which insulation tests and creepage paths apply. The highest rated operating
voltage must never be higher than the rated insulation voltage.
➜ Rated operating voltage
Rated short-circuit breaking capacity (I
The highest current that a switching device can break at rated operating voltage and
frequency without damage. It is specified as an rms value.
➜ Rated operating voltage
Rated short-circuit making capacity (I
The highest current that a switching device can make at a specific rated operating voltage
and frequency without damage. Contrary to the other characteristic data, it is specified as a
peak value.
➜ Rated operating voltage
Conditional short-circuit current, rated DIN EN 60947-1; 2.5.29
