Product Details

Product description:

The circuit breaker has traditional protection functions such as overload, short circuit, and undervoltage. It also has functions such as more optimized volume, built-in communication, power measurement and management, which improves the reliability and safety of power supply.


Applications and functions:

Incoming-feeder and outgoing-feeder function in distribution systems

Switching and protecting large powers, motors, capacitors, generators, transformers, busbars and cables

Overload protection

Short-circuit protection with short delay

Instantaneous short-circuit protection

Used in building, industry, energy and infrastructure



1.Low space requirements:

3SW68 devices are very compact thus require very little space for installation. Size A devices (up to 1600 A) fit into a 400 mm wide switchgear panel.

Size B,C,D devices (up to 6300 A) are the smallest of their kind and with their smallest construction width  fits into a 800 mm wide switchgear panel.

2.Modular design:

Components like auxiliary releases, motorized operating mechanisms, electronic releases, current sensors, auxiliary circuit signaling switches, automatic reset devices, interlocks and engagement operating mechanisms can all be exchanged or retrofitted in the back ground, thus allowing the circuit breaker to be adapted to new, changing required.


The use of modern communication-capable circuit breakers opens up completely new possibilities in terms of start-up, parameterization, diagnostics, maintenance and operation. This allows varieties of ways of reducing costs and improving productivity in industrial plants, buildings and infrastructure projects.

4.Easy wiring by different terminals:

A wide variety of terminals are offered, to guarantee an optimal solution for connection to the power circuit under different applications.
