The Bulletin 1492-RCD line includes residual current devices, also known as residual current circuit breakers, for detecting and interrupting leakage current to ground, by detecting small leakage currents and disconnecting all ungrounded connectors quickly, RCDs can prevent injury to exposed personnel and damage to equipment, RCDs are used in series with miniature circuit breakers for additional circuit protection from not only overload and short circuit, but also ground fault, many short circuits begin as undetected ground faults, using an RCD in an application may detect problems before costly equipment damage and downtime occurs, these devices are type A residual current devices to IEC standards.
