1200V DC CURRENT DISCONNECT SWITCH IEC60947.3

A 1200-volt DC isolator switch is a crucial component in a solar energy system that disconnects the direct current (dc) from the solar panels and other system components.

One of the primary reasons for using a DC isolator switch is to ensure the safety of people working on the solar energy system. In the event of a fault or during maintenance, a DC isolator switch can disconnect the system, preventing electrical shock and reducing the risk of fire.

The MDIS compact switch body design is suitable for built-in DC isolator switches in solar inverters, solar combiner boxes, and other DC applications.

COMPONENTS OF 1200V DC ISOLATOR

Switching mechanism
The switching mechanism is the heart of a DC isolator switch. It is responsible for making or breaking the electrical connection within the device. The mechanism is designed to handle high voltages, such as 1200 volts, and can withstand the stresses associated with repeated switching.

Enclosure
The enclosure houses the switching mechanism and other components, providing protection from environmental factors such as dust, moisture, and UV radiation. The enclosure should be made from durable materials, such as polycarbonate or stainless steel, to ensure long-lasting and reliable performance.

Arc-extinguishing technology
When disconnecting high voltage DC, arcs can form, which pose a risk of fire and equipment damage. To mitigate this risk, a 1200-volt DC isolator switch employs arc-extinguishing technology, which can be either mechanical or electronic. This technology ensures that any arcs formed during the switching process are rapidly extinguished.

    please feel free to contact us.

    A: A 1200-volt DC isolator switch is a device that disconnects the solar panels from the rest of the solar system, while a solar PV combiner box is used to combine the outputs of multiple solar panel strings into a single output that can be connected to the inverter.

    A: No, a single 1200 DC isolator switch can be used to disconnect an entire solar array or individual strings of solar panels. However, depending on the system design and local regulations, you may need additional isolators for specific parts of your solar system, such as the inverter or char-voltage controller.

    A: Installing a 1200-volt DC isolator involves working with high-voltage components and should only be done by qualified professionals with experience in solar system installation and maintenance. Attempting to install an isolator without the proper knowledge and skills can result in serious injury or damage to your solar system.

    A: To ensure the long-term reliability of your 1200-volt DC isolator, conduct regular inspections and adhere to the manufacturer’s recommended maintenance schedule.

    A: A 1200 volt DC isolator offers several benefits for large-scale solar installations, including greater scalability and flexibility, reduced power losses, and improved system reliability.

    A: Arc-extinguishing technology is employed in a 1200-volt DC isolator to rapidly extinguish any arcs formed during the switching process, minimizing the risk of fire and equipment damage.
