Residual current circuit breaker iID-40-4-30-A 40A 4-pole 30mA, type A A9Z21440

Residual current devices of the iID Schneider Electric series 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), operational safety (can be checked with the "T" button only once a year, terminal plugs when tightening the wires) as well as the ability to communicate through the Smartlink system using an auxiliary contact confirming the state of the switch and the cause of trip.
