Employs a two-tiered protection approach with residual current devices in both the final switch boxes and the preceding sub-distribution or main distribution boxes. The principle of "one machine, one switch, one leakage, one box, one. After stepping down the voltage through the transformer's low-voltage side (0. 4kV), power distribution is achieved through three levels of distribution boxes: the main distribution board, secondary distribution boards, and tertiary distribution boards. Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers.
Fuses in the unit: Each cooling unit has its own protection against overload and short circuit. Overvoltage protection: It is recommended to install external protection in the distribution panel, especially in areas with frequent voltage fluctuations. All cables are brought together here and connected according to the wiring diagram supplied. Ice conduces unwanted freezing of elements such as cold store doors/ gates or door frames and can cause: damage to the door structure, weather stripping, disabling closing the door tightly and leading to incr ased energy consumption, etc. Another problem, that occurs.
