Product Description
The modular low-voltage load isolation switch can achieve different functions by mechanically adding various add-ons. It can be installed in a variety of ways to cope with different use cases. Through the above two points, it can provide solutions for many special occasions.
Optional add-ons
1. Add additional poles (there are 4 kinds of additional poles) to turn the 3P isolation switch into a multi-pole isolation switch.
2. Add auxiliary contacts (there are 3 kinds of auxiliary contacts), which can increase the function of pre-breaking and position indication.
3. Use the conversion kit to convert two isolation switches into an isolation switch that can control two lines at the same time, or a  transfer switch.

Advantage
1. A simple mechanical combination of a standard 3-pole load isolator with optional add-ons can make dozens of products. It can provide solutions for a wide variety of special occasions without the need to develop an entirely new product for each special occasion. Thus greatly reducing the price of the product.
2. The product can be upgraded. In the future, when the product needs to add new functions, it only needs to develop new add-ons to upgrade into a new product.

3. This series of load isolation switch is designed, tested and verified according to the specifications defined by the standard IEC60947-3 and GB/T 14048.3-2017. This process guarantees a high level of product quality that can cope with a variety of challenging operating  environments.
