Disposing device DSH AIAR. 468243.002

The device is designed to bypass the trip coil of the circuit breaker and re-bypass it if it is necessary to turn off the circuit-breaker by short-circuit currents.


    The rated current of the current circuit of the device is DSH - 5 A.
    The number of bypass/re-bypass channels - 2 (phases A and C).
    Range of bypass currents - from 1,5 to 150 A.
Range of permissible impedance of bypass current circuits:
  • at a current of 1.5 A - not less than 1 and not more than 560 Ohm,
  • at a current of 50 A - not more than 20 Ohm,
  • at a current of 150 A - not more than 7 Ohm.
  • The maximum value of the current at which the technical characteristics of the device are provided is not more than:
  • ­ long 5 A
  • within 5 minutes 8 A
  • ­ within 5 seconds 75 A
  • within 1 second of 150 A.
  • The maximum power consumed by the DSH device for each phase in the course of a current of 5 A is not more than 12 W.
  • The maximum value of the voltage amplitude between the terminals of the current in the bypass coil is not more than 2.5 V.
  • The maximum value of the voltage amplitude on bypass coil with currents from 1.5 to 5 A in the bypass mode - not more than 1.5 V.
