The WTIS solar DC isolation switch is a device used in photovoltaic (PV) systems to isolate DC input from solar panels. It is usually installed in a junction box, which is a junction box that connects multiple solar panels together.
The DC isolation switch can disconnect the DC power supply in emergency or maintenance situations, ensuring the safety of the photovoltaic system. It is designed to handle the high DC voltage and current generated by solar panels.
The functions of solar DC isolation switches include:
Weather resistant and durable structure: The switch is designed for outdoor installation and can withstand harsh weather conditions.
Bipolar switch: It has two poles and can simultaneously disconnect the positive and negative DC circuits, ensuring complete isolation of the system.
Lockable handle: The switch may have a lockable handle to prevent unauthorized access or accidental operation.
Visible indicator: Some switches have a visible indicator light that displays the status of the switch (on/off).
Compliance with safety standards: The switch should comply with relevant safety standards, such as IEC 60947-3, to ensure safe operation.
