  • 32-product design serial number
  • 12-rated voltage(kV)
  • M-permanent magnet type
  • X1-rated current(A)
  • X2-rated short open circuit current(kA)
  •  Use of environmental conditions:
    • Ambient temperature: -40 to +40°C 
    • Altitude: ≤2000m
    • Earthquake intensity: ≤8 
    • Environment humidity: month average relative humidity ≤90%, daily average relative humidity ≤95%
    • Wind pressure: ≤700Pa (equivalent to wind speed 34m/s)
    • No fire, explosion, serious filthy, chemical corrosion and violent vibration of places
    • Customers have other special requirements, can be in order to put forward, our company can offer most satisfied
  • Features:
    • Equipped with vacuum arcing chamber of the column in vacuum circuit breaker (performance is stable and reliable, and has no combustion and explosion danger, safety, free of maintenance, small volume, light weight and long service life
    • Circuit breaker using permanent magnet operation system, the structure is simple, less parts, moving parts, only one, and the traditional spring institutions than nearly parts, greatly reduce the fault source, greatly enhancing the reliability\
    • Cancelled and prone to failure of mechanical off and lock device, make the whole system operation reliability greatly improved
    • Permanent magnetic actuator controller unique adaptive and self-check function, may to the of the pma optimization, make vacuum circuit breaker of mechanical properties to achieve the best, extending a permanent magnetic actuator and vacuum arcing chamber of life
    • Product the permanent magnetic actuator hold still, reliable and fast with the unique advantages, its inherent action time can\'t more than 10 ms and the action time consistent, very convenient at all levels in the circuit breaker protection parameter setting and action
    • Product of permanent magnet operation system has electric points off and loading manual USD (national patent) and emergency break-brake four functions
    •  Installed have three-phase protection CT, zero sequence voltage CT, AB alternate with, through the controller of the real-time monitoring upload inputs, and with the value is used in the comparison to determine the type of line fault, and the corresponding processing;
    • Operator seal in the switch internal, can avoid effectively switch from long outdoors environment and cause institutions rust
    • Operator novel, simple, reliable operation, small volume, mechanical life can reach 30,000 times
