Item Type: Photovoltaic DC Switch Model: LONQ-40 Material: PC Pole Quantity: 4P Rated Voltage: DC1200V Insulation Voltage Ui: DC1500V Rated Impulse Withstand Voltage Uimp: 8kV Rated Current: 32A Waterproof Grade: IP66 Falling Resistance: 1000/1700 Ambient Temperature: -40 to 85 Connection Type: M20 Connector Size: Approx. 161 x 104 x 111mm / 6.3 x 4.1 x 4.4in Introduction: The quick disconnect device provides additional safety and flexibility for your solar system when maintaining your solar system. This product allows you to quickly and conveniently disconnect the DC power supply between the solar panel and the inverter or battery. The new installation of solar photovoltaic systems has increased the demand for circuit breakers and over current protection devices capable of interrupting current at voltages up to 1500 Vdc. Some locations require disconnect switches. The PV system array will generate DC current, which needs to be disconnected for maintenance or safety. This quick disconnect switch is also suitable for applications such as cabins or holiday homes that do not require continuous solar power. Just disconnect your solar array and reconnect it if necessary.
