SCCR (short circuit current rating)
Minimum short-circuit current
2)
The fuse protection is implemented via the circuit-breaker -Q3, the specified currents correspond
to the factory setting.
The cabinet height increases by 10" (250 mm) with degree of protection IP21, and by 16" (400
mm) for degrees of protection IP23 (NEMA1 filtered), IP43 and IP54 (NEMA12 ventilated).
2)
Current required for reliable tripping of the contained protective devices.
