Schneider Electric iID series residual current circuit breakers allow for the implementation of protection against electric shock, while providing facilities for installation in the switchgear (tool-free installation on a DIN rail, double terminals up / down), safety of operation (possibility to check with the "T" button only once a year, terminal plugs when tightening the wires) as well as the ability to communicate via the Smartlink system using an auxiliary contact confirming the status of the circuit breaker and the cause of tripping.
