1、 Overview

The auxiliary switch of F15 series is suitable for high voltage switch operation.

Main features:

1. The DC contact is specially used to control the DC 220 V 110 V closing coil opening coil, the breaking current can reach 10 a when the breaking current is DC220 v.

2. Compared with the existing auxiliary switch, the contact has the advantages of reliable connection, oxidation resistance corrosion resistance.

3. This series of auxiliary switch has the advantages of simple structure, convenient use long service life, which is an ideal replacement product.

2、 Service conditions

1. The ambient air temperature is - 40 ℃ ~ + 40 ℃;

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

3. The conditions are as follows: the average value of relative humidity measured within 24h does exceed 95%; the average value of water vapor pressure measured within 24h does exceed 2.2kpa; the average value of monthly relative humidity does exceed 90%; the average value of monthly water vapor pressure does exceed 1.8kpa, the condensation on the product surface due to temperature change is considered.

4. The acceleration shall be greater than 15m / S;

5. The air is obviously polluted by dust, smoke, corrosive combustible gases, steam salt spray.

5、 Structural features

1. The contact is a bridge type double break point structure, the contact material is agnilo;

2. The switch contact can be installed with permanent magnet arc extinguishing, the quantity can be made according to the user's requirements;

3. It can be made into various delay contacts, users need to provide clear technical requirements.
