HHD11-D adjustable over/under voltage protection with time delay
protection relay with phase lost phase sequence protection
multi-function relay Product DescriptionHHD11 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.HHD11-D Adjustable over/under voltage protection with
