SCDB Distribution Box

The SCDB distribution box is a widely used low-voltage electrical distribution device in industrial and civil buildings. It is mainly used for power distribution, control, and protection, and is suitable for three-phase three-wire, three-phase four-wire, and three-phase five-wire systems with a rated frequency of 50Hz and a rated voltage of up to 500V. The product features a closed structure, with a box body made of cold-rolled steel sheet and a surface treated with powder coating, offering high protection ratings. It supports both surface mounting and flush mounting methods. Equipped with circuit breakers, residual current devices (RCDs), contactors, and other components inside, it can provide overload, short-circuit, and leakage protection, as well as support for energy metering and signal indication functions. The distribution box is applicable to various scenarios such as factories, residences, shopping malls, and schools, and can meet the power supply needs of different users.

  • Power Distribution: Used to allocate electrical power to different devices or areas. It can distribute the main power supply to multiple branch circuits to meet the power needs of different users.
  • Control Functions: Equipped with various control components (such as switches, contactors, and relays), it can control the start and stop of electrical devices.
  • Protection Functions: Installed with protective devices such as circuit breakers, fuses, and residual current devices (RCDs), it can provide protection against overloads, short circuits, and leakage currents in the electrical circuit.
  • Energy Metering: It can also be fitted with electricity meters to measure power consumption.
  • Signal Indication: Typically equipped with indicator lights and meters to display the operating status of the distribution box.
