Summarize

      This series exchange contact device, mainly uses in to exchange 50Hz or 60Hz, the fixed insulation voltage is 660V~1000V, when the AC-3 use category the fixed working voltage is 380V the fixed operating current is in the 9A~400A power circuit. Mainly puts through for the long-distance range with the minute breaks using of the electric circuit, and is suitable for the control motor starting, stops and the reverse.
       This product conforms to standard and so on IEC60947-4-1, GB14048.4 .

Type & Meaning

Use environmental condition

3.1 ambient environment temperature : -25℃~+55℃;
3.2 Air relative humidity: When +40 ℃ does not surpass 50%; Is comparing a low temperature degree-hour of permission to have a higher relative humidity;
3.3 Altitude above sea level: Does not surpass 2000m;
3.4 Atmospheric condition: Has not been able to cause the explosion hazard medium also not to have to be able the dipping and destroys the insulator the gas and the electric conduction dust;
3.5 Installs in the not remarkable undulation and the impact vibration place;
3.6 Installs is not having the rain attack the place;
3.7 Control voltage permission change scope: 0.8~1.1Us.

Structure characteristic

4.1 Overall structure:
      The host, the auxiliary contact material are made by the electricity performance superior silver alloy, has the service life long and the good contact reliability. The explosion chamber assumes the enclosed type, and has the anti- burning material to prevent the electric arc to splatter to outside, Ie <= 22A separates the arc board without the extinguishing of arc, Ie >= 32A is loaded with the metal to separate the arc board, guaranteed the person and approaches the electric appliance the security. The binding post screw uses new from rises the bolt, the tile shape pad and the bolt does not separate may save the wiring with the time.
4.2 Contact system:
      The host, the auxiliary contact material are made by the electricity performance superior silver alloy, has the service life long and the good contact reliability. The explosion chamber assumes the enclosed type, and has the anti- burning material to prevent the electric arc to splatter to outside, Ie <= 22A separates the arc board without the extinguishing of arc, Ie >= 32A is loaded with the metal to separate the arc board, guaranteed the person and approaches the electric appliance the security. The binding post screw uses new from rises the bolt, the tile shape pad and the bolt does not separate may save the wiring with the time.
4.3 Magnetism system:
        Electromagnetic system work reliable, loses, the noise slightly low, has the very high organization intensity, the graph terminal is loaded with the voltage specification the mark sign, marks the sign voltage rank to spread has the specific color, clear striking, the wiring is convenient, may avoid because of meeting the wrong voltage specification to cause the coil to burn down.
