MQZ1,2,3,5 and 6 D.C. traction electromagnet is mainly used in the
control circuit of DC 220V, as the electromagnet coil for switching of
motorized operating device of vacuum circuit breaker and switchgear
incoming/outgoing cables.
MQZ4 D.C. electromagnet coil is used for the control circuit of D.C. 220V,
which is dedicated for the hydraumatic solenoid valve of hydraumatic disc
spring stored energy operating devices. The coil is thermo-plastic coated with
superior temperature tolerance.
MQZ7 D.C. electromagnet coil is used for the control circuit of D.C. 220V,
which is dedicated for the solenoid valve of pneumatic operating mechanism of
vacuum circuit breaker. The coil is thermo-plastic coated with superior
temperature tolerance up to class H.
MQZ8 D.C. electromagnet coil is used for the control circuit of D.C. 220V,
which is dedicated for the solenoid valve of pneumatic operating mechanism of
high voltage disconnector. The coil is thermo-plastic coated with superior
temperature tolerance up to class H.
