Use of 3KC4 and 3KC8 transfer switching equipment
The 3KC4 and 3KC8 transfer switching equipment is used to ensure a continuous supply of
power. The equipment enables reliable transfer between a main source and an alternative
source, thus a power supply is provided by means of an emergency source if the main
source is not available.
The three switch positions of the 3KC4 and 3KC8 series enable maximum stability of the
load power supply, in which case only minimum interruption to the power supply occurs.
