Description

Rated making capacity
The rated making capacity of an equipment is a value of current, stated by the
manufacturer, which the equipment can satisfactorily make under specified
making conditions.
Rated breaking capacity
The rated breaking of an equipment is a value of current, stated by the manufacturer, which the equipment can satisfactorily break, under specified breaking
conditions.
Rated ultimate short-circuit breaking capacity (Icu )
The rated ultimate short-circuit breaking capacity of a circuit-breaker is the
maximum short-circuit current value which the circuit-breaker can break twice
(in accordance with the sequence O – t – CO), at the corresponding rated
operational voltage. After the opening and closing sequence the circuit-breaker
is not required to carry its rated current.
Rated service short-circuit breaking capacity (Ics )
The rated service short-circuit breaking capacity of a circuit-breaker is the
maximum short-circuit current value which the circuit-breaker can break three times in accordance with a sequence of opening and closing operations
(O – t – CO – t – CO) at a defined rated operational voltage (Ue
) and at a defined
power factor. After this sequence the circuit-breaker is required to carry its
rated current.
Rated short-time withstand current (Icw )
The rated short-time withstand current is the current that the circuit-breaker in
the closed position can carry during a specified short time under prescribed
conditions of use and behaviour; the circuit-breaker shall be able to carry this
current during the associated short-time delay in order to ensure discrimination
between the circuit-breakers in series.
Rated short-circuit making capacity (Icm )
The rated short-circuit making capacity of an equipment is the value of shortcircuit making capacity assigned to that equipment by the manufacturer for the
rated operational voltage, at rated frequency, and at a specified power-factor
for ac.
