This 2-pole, 1P+N device occupies 2 modular width units (36 mm) on a DIN rail and is designed for 50 Hz AC systems.
The 40 A rated current and C characteristic mean this RCBO is intended for circuits with moderate inrush currents — common for lighting banks, small motor loads, and general-purpose socket outlets. It does not detect pulsating DC or smooth DC fault currents, so for circuits with variable-speed drives, UPS systems, or EV chargers, a Type A or Type F RCBO would be required. The EN 60898 rating governs its use in domestic-type installations; the higher IEC 60947-2 rating applies when installed in industrial distribution boards with higher prospective fault currents.
IP20 rating applies once the distribution board is installed with conductors connected — this is a panel-internal device, not for outdoor or washdown locations.
