Having acquired many years of experience in developing and producing switching devices, R&S can offer reliable and high-quality disconnectors, earthing switches and circuit breakers for medium-voltage applications.

All of our switches can be delivered with manual drives or motor drives and with earthing switches too.

Voltages: from 1 kV up to 38.5 kV
Rated current: up to 10,000 A
Rated short-time currents: up to 80 kA

Benefits that speak for themselves

Achieve highest efficiency levels
Our circuit breakers have been designed with the primary aim of increasing plant efficiency in mind.
Save time and hassle
From consulting, designing and installation, to aftersales services and spare parts supply, our experts guide you through the entire product lifecycle.
Increase your system’s reliability
The switches are highly reliable even in the most challenging of environmental conditions, including those encountered in coastal applications, in areas with high temperature fluctuations and in places where there is a high probability of icing.
Simplify maintenance
R&S offers comprehensive aftersales services. Our highly qualified employees are renowned for their high-quality work and are happy to carry out servicing for you directly on your premises. We also offer you the option of training your own staff, so that they can perform installation and inspection work independently.
Cut your retrofit costs
To keep the workload minimal during replacement projects in existing substations, R&S can supply disconnectors with the exact same connection points as the installed devices. We can also rebuild or overhaul devices in third-party manufacturers’ discontinued product lines.

We would like to deliver our 38.5 kV disconnectors as a standard product for the end customer Ørsted A/S. R&S SERW not only delivers high-quality products including after-sale service but also provides on-site training for the local workers.

We tailor our solutions to you

We offer our disconnectors and circuit breakers in single-pole, double-pole or three-pole variants. The switches are suitable for indoor and outdoor use. If none of our standard solutions meet your requirements, we also offer custom-made products.

Disconnector outdoor design

- Single-pole, double-pole or three-pole versions
- Clearly visible disconnection between two circuits in the network
- Knife-type design

Disconnector indoor design

- Single-pole, double-pole or three-pole versions
- Clearly visible disconnection between two circuits in the network
- Knife-type design

Circuit breaker outdoor design

- Switches operating currents and low overload currents, plus (in the event of network failures) high overload currents and short-circuit currents
- Maintains the residual currents for a given period of time and then switches off safely
- Equipped with a spring mechanism
- Single-pole, two-pole and three-pole design
