KDB002rated insulation voltage, ACREAL_MEASURE_TYPE

phase to neutral or phase to phase voltage value assigned to the connecting device by the manufacturer, this device being intended to be used in installations, the AC voltage supply of which does not exceed the rated insulation voltage of the connecting device itself

KDB003power losses per pole, ACREAL_MEASURE_TYPE

power dissipation calculated for one pole on the basis of the voltage drop measured at AC rated current under steady state conditions between its terminals

KDB020overvoltage categoryENUM_STRING_TYPE

numeral defining a transient overvoltage condition

KDB021number of switched polesENUM_STRING_TYPE

number of electrically separated conducting paths, each provided with a contact intended to connect and disconnect the main circuit of a switching device

KDB025rated operational voltage for IT systems, ACLEVEL(MAX) OF INT_MEASURE_TYPE

maximum value of the AC rated operational voltage for which the device is suitable for use on IT systems
