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.

 

Communication

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.

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.
