The unit is characterised by its reduced dimensions (2 modules mounted on a DIN rail).
It has been designed for single-phase, three-phase or three-phase with neutral low voltage
electrical installations. It is suitable for all neutral rates (VT, TN, IT), either as the main protection
element (MRCD) or for complementary purposes (RCM).
In the case of VT/TN-S systems, it can be used as a MRCD (IEC 60947-2) or a RCM (IEC
62020). It can only be installed as an RCM in other systems.
