Product Description

HHD10-A Phase Sequence Protection Relay AC400V 50Hz

Product Description
HHD10 series Phase sequence protection relay ( brief as protection relay) suitable for the power supply circuit with AC 50Hz, rated voltage 380V, together with AC contactor or other switching device to form as motor control circuit.  When the main circuit of the motor is in an abnormal state, disconnect the contact of the switching device in time to disconnect the three-phase power supply of the motor and protect the motor quickly and reliably.
  The protection relay adopts voltage sampling mode, which is independent of the power of the motor, and there is no need to set and adjust any current level. The product has the advantages of wide application range, simple and convenient use, stable and reliable performance and so on.
