NL7-63 Series DC Miniature Circuit Breaker Application

  NL7-63 PV NP DC breaker supplementary protectors are designed to provide overcurrent protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required. Devices are designed for direct current (DC) control circuit applications.

 

  NL7-63 series have protective function as shortage as overload,  which are used in lighting distribution system in commerce and dwelling, and protect fractional electric motors. They also have many merits of high protective grade(up to IP20), high breaking capacity, reliable sensitive action, convenient, multi pole assembling, long life etc.
  They are mainly adapted to the circuit of AC 250V in single pole, 415V in double, three, four poles for protecting overload and short circuit. Meanwhile, they are also used in turning on or off the electric apparatus and lighting circuit under the normal conditions.
