1, dc contactor CZ - code
2, H - representative for working condition of transformation or reverse
3, - - - basic specifications codes to rated current value
4, / 20-2 - set of normally open the main contact number and group number 0 - normally closed the main contact
Product structure features:
Product structure is simple, compact, small volume.Use a transformation contactor the reversal of the dc motor control can be realized and different task switching circuit.When using cross bus, can achieve the same dc motor reverse control;When does not use cross bus, can realize task switching with two different load lines.
The normal work and installation conditions:
1, the installation location of height is not more than 2000 meters above sea level;
2, ambient air temperature limit to + 40 ¡æ, offline for 25 ¡æ;
3, the surrounding air relative humidity less than 90% (average no more than the wettest month + 25 ¡æ;
4, the contactor pollution levels for 3 class;
5, contactor can be installed in horizontal or vertical, but the vertical installation shall be maintained when using two coil for the symmetric distribution;
6, seismic: in vertical, horizontal, vertical can withstand the frequency of 10 hz, 2 min 3 g shock vibration.
