With an extensive product range, the experts in protection against residual currents provide the right solution for any requirements. Doepke´s residual current circuit-breakers stand for the very highest quality and reliability. The company, based in Norden in the German state of Lower Saxony, has more than 300 employees at four sites around the world.

Products and services

Residual current circuit-breakers, Miniature circuit-breakers, RCCBs with overcurrent protection, Arc fault detection devices, Circuit-breakers with residual current trip, Modular residual current devices, Residual current monitors, Twilight switches, Load disconnectors, Installation relays, Pulse relays.
Dasy and Dasy TC bring light to the darkness

Energy-efficient, automated lighting control is provided by the Dasy and Dasy TC twilight switches from Doepke.
They switch on the connected light when the daylight is no longer sufficient, and also switch it back off when it gets light again. They are prevented from responding to short-term influences. Additional the Dasy TC combines twilight switches with a time switch. Dasy and Dasy TC can be installed on walls and masts and are available in white and anthracite.

Residual currents circuit-breakers DFS 2 B for the most limited spaces protects thermal pumps and PV systems

What makes the new, AC-DC sensitive DFS 2 B residual current circuit-breaker so unique is its particularly compact design. It only occupies 2 MW when installed, making retro-fitting especially easy. It is the ideal solution for protecting electrical installations that use electronic consumers and frequency converters with operating frequencies extending into the kilohertz range. Examples of these include thermal pumps and photovoltaic systems as well as charging points for electric vehicles.

Finding the right device for youSelection tool and guidelines from Doepke for selecting residual current circuit-breakers

There is not just one kind of RCCB (Residual Current operated Circuit-Breaker), rather a whole range of different types: two or four-pole, residual current type AC (detect AC residual currents and are not permitted in Germany), A (for AC and pulsating DC residual currents), F (also detect mixed frequencies) B and B+ (AC-DC sensitive). RCCBs can be slow-blow versions or have increased surge current strength, have selective tripping, be specifically tailored to the requirements of electromobility, be adapted for harsh environmental conditions or be built for facilities at risk of fire.

The guidelines for selecting residual current circuit-breakers and the selection tool from Doepke provide reliable assistance in finding your way.
You will find the digital selection tool on the Doepke corporate website:

E-mobility: charging equipment protection made easy

Doepke has developed the new DFS4 F EV mixed-frequency-sensitive residual current circuit-breaker specifically for protecting charging points. By using this product, electricians can always stay on the safe side: it not only detects AC residual currents and pulsating DC residual currents, but also residual currents with mixed frequencies deviating from 50 Hz. What is special about the EV model is its integrated DC residual current detection. Because of this, the new residual current circuit-breaker trips reliably if smooth DC residual currents higher than 6 mA occur when an electric car is charged.

The 4 module width unit is easy to install and protects the charging point, as well as any upstream residual current circuit-breakers without DC residual current protection, against blinding. It has greater immunity to surge currents up to 3 kA, and is also lightning-resistant due to its short time delay. This reduces unwanted tripping overall.

Miniature circuit-breakers – safety in line with UL standards
Production standards in North America, and in some other countries, are far stricter than they are in Europe. This is because UL standards apply here. UL (Underwriters Laboratories Inc.®) is one of the leading organisations for testing and certification in the area of product security. Since 2019, Doepke has been expanding its production of miniature circuit-breakers and therefore also its product portfolio: the three product series DLS 7, 8 and 9 are optimised for various applications in industry and plant engineering. All three offer maximum space savings thanks to their compact construction, enabling convenient wiring and maximising safety. This is because they are all UL-certified and therefore also meet the requirements for the US market. The special busbar system enables easy and fast installation in the network. What’s more, it is also possible to connect a multitude of additional devices, such as operating current trips, fault sensors and auxiliary sensors.
