There are residual current circuit-breakers for a variety of different applications. It is not particularly easy to navigate your way around them and choose the right model for your needs. This app takes you through the extensive product range and guides you to the right residual current circuit-breaker for you in just a few clicks. The app uses a series of questions to pinpoint your precise needs, for example whether you need increased availability or whether you are using electric equipment with pulse-like surge currents. You will also be asked about the environmental conditions. If the electrical system is being operated within an installation where the upstream protective device is not known or is unsuitable for a conventional residual current trip, the app knows the right answer and is guaranteed to take you to the suitable category or exactly the right residual current circuit-breaker that perfectly meets your individual requirements. Clicking on the button βOpen in browserβ takes you to the Doepke website, where the right kinds of products will be displayed for you to choose from. The app also enables you to scan QR codes on Doepke residual current circuit-breakers to find out more detailed information about them at any time. The Doepke selection guide app is free of charge.
