PROFESSIONAL ISOLATION SWITCH MANUFACTURER

The primary purpose of an isolator switch is to provide an extra layer of protection by disconnecting electrical devices or circuits from the power source. This disconnection is crucial during maintenance, inspection, or repair work, as it minimizes the risk of electric shocks or short circuits, ensuring the safety of personnel and equipment.

Our isolating switch is specially designed for disconnecting the AC and DC sides of the solar system. Due to its excellent quality performance, we have reached cooperation with many big brands. Combined with other accessories, our switches can provide effective protection against any kind of overvoltage or overload problem.

Due to our stringent quality process, we ensure that our disconnectors are inspected and tested at every production step. IP66 shells and MC4 connectors are available for your own selection. Contact us now to enjoy super-value discounts, move forward with us, and represent our products!

Frequently Asked Questions

You'll find answers about our products. If your question is not answered below,
please feel free to contact us.

Are isolating switches and circuit breakers the same?

No, an isolating switch is not the same as a circuit breaker. A circuit breaker is an automatic isolating switch that provides Circuit Protection, while an isolating switch disconnects an electrical device or circuit from the power source for safety purposes.

How often should I inspect and maintain my isolating switch?

It is recommended that the isolation switch be inspected and maintained at least once a year to provide Circuit Protection. Of course, the frequency of inspection and maintenance depends on the specific switch and its operating environment. If the switch is exposed to harsh environmental conditions, the isolation should be inspected and maintained more frequently. switch.

Can I install the isolator switch myself?

It is strongly recommended not to install an isolator switch yourself unless you are a qualified and licensed electrician. Improper installation can cause accidents, malfunctions, and damage to the electrical system. Be sure to hire a professional to ensure the correct and safe installation of the isolator switch.

What is the main purpose of the isolating switch?

The main purpose of an isolating switch is to disconnect a specific circuit or equipment from the main power supply to ensure the safety of personnel and equipment during maintenance, inspection, or repair work.

Does the isolation switch need to be replaced?

If isolating switches are well maintained and used correctly, they can have a long service life. However, over time, wear may occur and the switch may need to be replaced. Regular inspections and maintenance can help detect problems early and allow you to replace the switch before it fails or causes damage to your electrical system.

What are the common applications of isolating switches?

Isolating switches are commonly used in a variety of applications, including power systems, industrial equipment, and residential environments. They help ensure the safety of personnel and equipment by disconnecting specific circuits or equipment from the main power supply during maintenance, inspection, or repair work.

Can isolating switches be used to prevent electrical faults?

Isolating switches by themselves do not provide protection against electrical faults such as overcurrent or short circuits. However, they can be used in conjunction with other protective devices, such as circuit breakers or fuses, to provide a comprehensive protection solution for your electrical system.

What should you pay attention to when choosing an isolation switch?

When selecting an isolation switch, consider whether you need an AC isolator switch or a DC isolator switch, including factors such as voltage rating, current rating, load type, environmental conditions, and safety features. These factors will help you choose a switch that is compatible with your specific application and provides the necessary protection and performance.

What specific safety precautions need to be followed when operating a DC solar isolator switch?

To ensure the safe operation of your DC solar isolator switch, always follow the manufacturer’s guidelines and adhere to relevant codes and regulations. Some general safety precautions include:

Before operating the isolating switch, turn off the power supply.

Use appropriate personal protective equipment (PPE) when working with electrical systems.

Ensure that the isolating switch remains in the closed position during maintenance or repair work by using built-in safety features such as interlocking and padlocking devices.

Can the isolation switch be operated remotely?

Some isolating switches, especially electrical isolators, can be operated remotely using a control system. This improves safety and convenience as operators can disconnect a specific circuit or device from the main power supply without having to physically interact with the switch.
