The 6000 A Icn breaking capacity at 230...240 V AC 50 Hz, compliant with EN/IEC 61009-2-1, means this RCBO can safely interrupt fault currents up to that level without welding its contacts or cascading failure upstream — sufficient for most residential and light commercial final circuits where the prospective short-circuit current stays under that threshold.
The B-curve (magnetic tripping limit 3...5 x In) means the device trips instantaneously between 18 A and 30 A — suited for resistive and general-purpose loads with low inrush, such as lighting circuits, socket outlets, and small control transformers. The 30 mA residual sensitivity provides personal protection against direct contact faults, compliant with IEC 60364 requirements for socket-outlet circuits. Thermal-magnetic trip technology combines a bimetal strip for overload protection and a solenoid for short-circuit detection, giving a time-current curve that coordinates with downstream MCBs and upstream fuses.
Installation and wiring
Terminals accept 1...16 mm² rigid or 1...10 mm² flexible conductors; strip length 15 mm, tightening torque 2 N.m. The toggle provides local ON/OFF/fault-trip signalling. Electrical and mechanical durability are both rated at 20,000 cycles.
