HT1-16 Universal transfer switchDetailed product description：

The HT1-16 universal transfer switch (hereinafter referred to as the switch) has a specified heating current of 16A and is mainly used for converting electrical control lines (electromagnetic coils, electrical measuring instruments, servo motors, etc.) in circuits with 50Hz, voltage up to 380V, and DC voltage up to 220V. It can also be used for direct control of three-phase cage induction motors with AC 380V, 5.5Kw and below (starting, reversible conversion, and multi speed motor speed change, etc.).

Normal working conditions
1. The ambient air temperature shall not exceed+40 ℃, not be lower than -25 ℃, and its average value within 24 hours shall not exceed+35 ℃.
2. The altitude of the installation location shall not exceed 2000m.
3. The relative humidity of the air at the installation location shall not exceed 50% at a maximum temperature of+40 ℃; Higher relative humidity is allowed at lower temperatures, with the average minimum temperature of the wettest month not exceeding+25 ℃ and the average maximum relative temperature of that month not exceeding 90%. Due to temperature changes causing condensation on the product, measures must be taken.
4. The pollution level is level 3.
5. The installation category is Class III.
6. The switch should be installed according to the user manual provided by the manufacturer.
