Low-voltage switchgear

The increased requirements for personal and operator safety are important factors that need to be taken into account when using switchgear. Simultaneously, the demand for system availability is increasing. To satisfy these demands, our switchgear and controlgear is manufactured according to IEC 61439 guidelines and subjected to passive and active arc fault testing.

Like all our products, our low-voltage switchgear and controlgear stands for the highest quality and safety. We cater to customer-specific requirements and pay attention to our customers’ individual needs. With our team of electrical engineers and specialist personnel, we can realise special solutions quickly and effortlessly.

Our systems are design verified according to IEC 61439.

Vario Block TN

The VarioBlock TN is a low-voltage switchgear and controlgear system. It finds its place in various areas of application. The system is highly flexible and variable, thanks to the combination of different functions for power distribution, control and small outgoers, as well as panel variants with withdrawable technology and plug-in technology for circuit-breakers, in fixed installation and plug-in technology, for both fuse-switches and switch disconnector fuses.
