Practical application: allows for wide application in homes, shopping malls, factories, laboratories, farms and so on, very practical. 4. Safer for you: adopting fireproof plastic with excellent insulation performance, also allows you to switch and return yourself. 5. Easy to install: Specially designed for 100A 230V AC 50Hz 60Hz, the installation of this compact transfer switch is very easy. Specification: Item Type: Transfer Switch Product Model: NLQ4-125/2P Rated Current: 100 A Rated voltage: 230 V AC Insulation Voltage: 690 V AC Rated frequency: 50 Hz 60 Hz Electrical class: PC class insulation type. Rated pulse withstand voltage: 8 KV List of packages: 1 x transfer switch Note: 1. The maximum ambient temperature should not exceed 40 ℃, the minimum should not be lower than -5 ℃, and the average temperature within 24 hours should not be higher than 35 ℃. 2. The height of the installation site should not be higher than 2000m 3. When the maximum temperature reaches 40 ℃, the relative humidity at the installation site should not exceed 50%. When the temperature is the lowest temperature -5℃, the relative humidity is higher, for example, if the temperature is 25℃, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on the surface of the product due to temperature changes. Please check the integrity of ATS before installation, enable or disable ATS using the operating lever, check the transmission flexibility and detect normal and backup load generation and disconnection conditions at each stage.
