Mechanical automatic reclosing

  • DCKG-01-D10A, DCKG-02-D32A, DCKG-03-D63A
  • Sipibs

Product Description

It is wideiy used in three four wire neutral point directly grounded(TT system) LV grid to provide indirect contact protection against personal electric shock hazard and also is used to protect against grounding fault,over-current and short-circuit of circuit or equipments.When the circuit breaker trips because of Temporary earth leakage or instantaneous earth leakage or voltage fault caused by electric surge, the power can be restored directly through self re-closing function without manual operation.
1.Use module framework. Several modules can be selected flexibly.
2.Provides 8 protection functions such as overcurrent protection, leakage current protection, short circuit protection, overvoltage protection, undervoltage protection,  automatically disconnect when power off,test before closing,automatic reclosing
3.Fast and rapid breaking capacity: built-in CPU, the implementation of online detection, when the occurrence of undervoltage, overvoltage, leakage, overload, short-circuit and so on quickly cut off power, the first time to protect the personnel and base station security.
4.Have a reasonable lightning protection performance: Built-in two-way surge absorption switch, to the power line induction from the lightning interference has inhibitory ability, at the same time, according to user requirements external Lightning protection module, line surge shielding to achieve the base station power supply lightning protection requirements.
5.Small size and compact configuration.

Product Advantages
1.Protection of equipment Property safety.
2.Safeguard electricity Safety.
3.Ensure continuity of Base station power supply.
4.Reduce maintenance costs.
5.Reduce cost loss.
6.Improve service quality and improve product advantage.
