The Schneider Electric A9D15806 is an Acti9 iC60H RCBO — a combined residual current device and miniature circuit breaker in a single 18 mm wide module. It protects a 1P+N final subcircuit against both overload/short-circuit (thermal-magnetic trip, C-curve) and earth leakage (100 mA sensitivity). The 10 kA Icn breaking capacity at 240 V AC meets the requirements for most commercial and light industrial distribution boards, and the part is certified to IEC 61009-1 and IEC 61009-2-2.
The 6 A rated current at 50 °C is the continuous current the RCBO can carry without tripping in a 50 °C ambient — derate further if the panel runs hotter. The 100 mA earth-leakage threshold is a protection against fire risk from persistent leakage, not personnel shock protection (30 mA is the standard for human contact). In a TN earthing system, the single-pole switched neutral on the left matches standard distribution board busbar arrangements.
Clip-on mounting to DIN rail, 18 mm width (2 × 9 mm pitches). The top terminal accepts up to 25 mm² rigid or 16 mm² flexible; the bottom terminal accepts up to 16 mm² rigid or 10 mm² flexible. Tightening torque is 3.5 N·m on the top and 2 N·m on the bottom. Strip length is 14 mm for the top connection, 13 mm for the bottom. The toggle provides local ON/OFF indication, and the unit is padlockable with a Ø 4 mm padlock for lockout/tagout.
