With the ISΩ HD design, there are now AC-DC sensitive residual current circuit-breakers that are audit-proof. Insulation testing can therefore be carried out without prior disconnection.
This not only prevents wear caused by mechanical stress from connecting and disconnecting, but it also saves a substantial amount of time as it removes the need to disconnect the residual current circuit-breaker. How much difference does this make? Watch the latest video on the Doepke YouTube channel, which compares residual current circuit-breaker measurements with and without ISΩ function to find out.
Type B Doepke residual current circuit-breakers in the ISΩ HD design can handle up to 63 A rated current and 500 mA rated residual current.
Alongside the latest product videos, you’ll also find recordings of previous webinars on the Doepke YouTube channel, as well as a virtual tour of the Doepke trade fair stand with new products and the latest trade fair highlights.
