What is the difference between 380V and 220V electric contact pressure gauge?
The difference between the 380V and 220V electric contact pressure gauges is that the rated voltage of the action coil is different. The rated voltage of the action coil of the 380V electric contact pressure meter is 380V, which can only be connected with the 380V voltage and is not connected to the 220V. 220V electric contact pressure meter action coil rated voltage is 220V, can only meet the 220V voltage, access to 380V will burn the coil.The rated voltage of the coil is 380V, the cross-sectional area of the conductor should be smaller, the coil number of coils should be more, and the operation current should be smaller. The rated voltage of the coil is 220V, the cross-sectional area of the conductor should be larger, the number of coils should be less, and the action current should be greater.
380 of the voltage can kill people, and 280 of the voltage can make the whole body numb
General electric contact pressure gauge contact is 5A380V, a normally open and normally closed contacts of two groups, the control circuit of the power distribution box is generally 220V, the control circuit is 380V, electric contact pressure gauge 380V means that the control circuit voltage limit can be connected to 380V, can also be connected to 220V, 220V can also be connected to the voltage. DC power can also, but not more than 5A
