Intelligent Controller
The intelligent controller for our universal circuit breaker is designed with an LCD display. It offers functions such as testing, load monitoring, information display, and communication, allowing the electrical switch to achieve four types of protections. The protection functions are long-term time delay, short-term time delay, instantaneous, ground fault or neutral phase, neutral phase current protection functions. Other auxiliary functions such as voltage display, low-voltage protection, remote control, and more are also achievable via the controller.

Derivative Products
1. Circuit breakers with low voltage protection function
This is an innovative design in both national and international market. The low voltage protection function is achieved via an intelligent controller. The minimum operation voltage, delay time, and low voltage protection can be set on site, which eliminates the need of a traditional under voltage release.

2. Wide voltage input breaker
The intelligent controller for this circuit breaker works at voltages from AC/DC80V to AC/DC 280V, so it is applicable for use in areas with voltage fluctuations usually. As compared with other types of electrical switches, this type features stable operation in high or low voltage ranges.

3. 3P+N breakers
This product is designed for the replacement of four pole circuit breakers in the power distribution system, in which the neutral phase is always connected. As compared with conventional 4 pole counterparts, 3P+N breaker has advantages that it is low cost, small sized, and easy for installation.

4. Breaker with position status output function
As its name indicates, this electrical switch is able to output the position status of drawer type breakers, thus allowing users to achieve remote monitoring of the devices' operation status.

5. Products with high and low temperature resistance function
This type of circuit breaker can be used in extremely high or low temperatures. It can be stored in temperatures from - 40℃ to 70℃, and can work at maximally 70℃ temperature if the working current is reduced correspondingly. Its minimum working temperature is -25℃.

Installation, Wiring and Interlock Instructions
The circuit breaker should be installed vertically and the vertical bank angle shall not exceed five degrees. Horizontal and vertical wiring ways are both allowable. Before installation, please make sure the product specification is surely suitable for your specific application. While installation, please be sure that the electrical device is protected with reliable ground connection. More detailed information are available in the PDF document.

Horizontal Vertical

In addition, the products can be interlocked.
1. Horizontal interlocking
Two drawer type circuit breakers can be horizontally interlocked using a steel cable.

2. Vertical interlocking
Two or three drawer type breakers can be vertically interlocked using connecting rods.

Product Structure Classifications
GSW1 universal circuit breaker includes drawer type and fixed type. The former has advantages such as easier installation and maintenance, while the latter features lower cost, lighter weight, and smaller size. Additionally, the two types are designed with different rated current, busbar and intelligent controller. Clients can choose an appropriate type according to their actual demands.

1. Drawer type 2. Fixed type
