The structure design material selection of the product are quite different those of the traditional switch. It has high technical content can be comparable with the advanced blue series switch abroad. It is of positive significance to improve the reliability product grade of complete equipment. Before model selection, please read the model feature description in detail, distinguish the difference between positioning type self recovery type. DC switch add dc220v after the model. This series of switch can be interchanged with CA10 series.

1、 Purpose

Lwz2 series change-over switch is mainly used for making, breaking converting circuits in circuits with AC 50 Hz, rated voltage up to 380 V DC rated voltage up to 220 V below, as well as direct control of small capacity motor master control.

2、 Structural type

1. Operation mode: there are positioning type, self recovery type, positioning self recovery type locking type (AS1, as2), etc. the key of AS1 type is in the center of the panel, the key is directly used as the handle. The key of as2 type is 40mm below the panel center, the handle can be locked at any position;

2. Operating angle: 30 °, 45 °, 60 ° 90 ° respectively. Generally, the self reset angle is 30 ° the positioning type is 45 ° 60 °;

3. Number of switch sections: there are 1-12 sections (generally 1-3 sections for self recovery type), each section has two pairs of double breakpoint contacts.

3、 Installation service conditions

1. The ambient air temperature does exceed + 40 ℃, the average temperature within 24 hours does exceed + 35 ℃;

2. The lower limit of ambient air temperature should exceed - 5 ℃;

3. The altitude of the installation site shall exceed 2000m;

4. When the maximum temperature is + 40 ℃, the relative humidity of the air is more than 50%. A higher relative humidity can be allowed at a lower temperature. Special measures should be taken for occasional condensation due to temperature change;

5. The switch is installed in the environmental conditions of pollution level 3;

6. The switch should be installed in an environment that can prevent rain, wind sand.
