DC Isolator Switch

Operating environment

● Altitude of 2000 meters and below, above 2000 meters need to derate for use, other special requirements, please contact the manufacturer;
● Ambient air temperature -25 ℃ to +40 ℃, 24-hour average temperature does not exceed +35 ℃;
● When the ambient air temperature is higher than +40°C or hell -25°C, please contact the manufacturer;
● The inner core of the product is installed in the distribution box, where there should be waterproof measures.

scope of application

ATPVSO series rotary isolating switches are mainly used for line isolation between photovoltaic modules and inverters in photovoltaic power generation systems. The waterproof performance of this product reaches IP66, and the inner core of the DC isolating switch can be installed inside the inverter for inverter incoming line control.

A1l photovoltaic installations must have a DC Switch to disconnect the DC/AC inverter from the photovolaic panels in accordance with IEC 60947-3.

The switch has 4 separate poles.

Links can be used to change the way that the poles are connected. Links can be used to change the way that the poles are connected.

Interconnection of the poles dominates the load that the switch can connect and break.

As the number of poles increases, the total load switching capacity of the device increases.

DC Isolator Switch Instructions

It is important to ensure that allelectrical connections (including factory connections) are tight enough that all terminal screws are tightened firmly.

It is recommended that for DC, multi-stranded cable, crimp ferules are used to ensure that the wires do not become loose. Loose cables can cause excessive watt loss and generate excessive heat causing serious damage to the switch.

After instaling and wiring the switch, the testing switches, on and off several times, are necessary for users and user must feel and hear the positive snap actions.

If the switch cannot be felt and heard to operate correctly then it is important that the switch i-s cannot be instaled.
