RESIDUAL CURRENT DEVICE GW90923 30MA/2X63A

ReStart Autotest automates the testing of residual current devices. If the residual current device is not tested regularly, the tripping mechanism may become stuck, which could result in the device failing to operate during a fault. ReStart Autotest automatically performs the required functional test every 28 days. ReStart Autotest residual current devices significantly save staff working time, while maintenance costs are also reduced. In some applications, such as solar power systems and electric vehicle charging points, type B residual current devices must be used. ReStart Autotest provides a solution even when the protected object requires a type B residual current device. The product is compatible with a fork-type current busbar.
