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!





Our team has continuously improved the structure and production process of the isolating switch and has obtained many patents for this. Our isolating switch has its own patents and special instructions, making it safer, faster, and more stable to use. With our isolating switches, arc interruption within 3 milliseconds can be achieved, quickly cutting off the circuit and protecting the system’s safety.


MOREDAY has realized the automatic production of 70% of the isolation switch process, ensuring that the yield rate of the isolation switch produced is above 99.8%. Our strong delivery capacity has made us a supplier to many international brands.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
