SERWYour partner for reliable HV switching devices
Today s energy transmission must not only meet a high degree of reliability, the products must also be designed to be efficient and long-lasting.
Thanks to many years of experience in the field of power pro-ducts with a focus on switching devices, it is possible for us to serve our customers as a competent and reliable partner. All products are precisely tailored to the requirements of the customer with regard to various criteria.
Originated from the Skoda factory in 1975 and headquarte-red in Pilsen, Czech Republic, SERW has developed into one of the leading switching device manufacturers in Europe.
The name SERW is today a synonym for reliability and quality in the market. Modern production processes, lean manufac-turing, highly qualified employees as well as an integrated management system are the guarantee for today´s success.
The right product for every applicationThe product portfolio includes switching devices for voltage ranges from 1kV up to 38,5kV.

DisconnectorsWe provide disconnectors for both indoor and outdoor use. All disconnectors can be delivered with manual or motor dri-ves. In order to keep workload at a minimum in course of replacement projects in existing substations, SERW can sup-ply switches with exactly the connection points of the instal-led devices. All our disconnectors can also be equipped with earthing switches.
SERW manufactures disconnectors for the voltage level up to 38,5kV with rated currents up to 6.300A and rated short-time currents up to 80kA. Higher rated currents after consul-tation.
The main strengths of our disconnectors:• Maintenance-free• Special solutions for high current applications• Knife type construction• Single-, double- and three-pole version• Earthing switch available as an option
The drives of our devices are mounted directly on the frame, on a special table or on the front of the cell. Project-specific design after consultation.

Circuit breakersVacuum circuit breakers are delivered for outdoor as well as indoor applications. The quenching of the arc takes place in the maintenance free vacuum chamber. All circuit breakers are equipped with a spring mechanism.
Circuit breakers can not only switch operating currents and low overload currents, but also in case of network failures high overload currents and short-circuit currents. Further-more they can hold the residual currents within a given peri-od of time and then switch off safely. SERW circuit breakers are produced both in single-, two- and three-pole design.
SERW circuit breakers have been designed with the primary aim of increasing the plant efficiency. The areas of applicati-
on range from energy distribution, industry to railway.
SERW manufactures circuit breakers for voltages up to 38,5kV, with rated current up to 1.250A and short-circuit po-wer up to 25kA.
The main strengths of our circuit breakers:• Long service life• Maintenance-free• Low weight• Single-, double- or three-phase design• Equipped with a drive
The drives can be mounted according to customer require-ments. Project-specific design after consultation.
