ISΩ HD – test-proof residual current protection
The repeated insulation measurements for electrical systems required by DIN VDE 0100-600 are often laborious. AC-DC sensitive residual current circuit-breakers must be disconnected beforehand, as otherwise the insulation test will give a false reading. With the new ISΩ HD design from Doepke, there are now AC-DC sensitive residual current circuit-breakers that are test-proof. Insulation can…
