At 6 A, it's sized for a branch circuit feeding a handful of outlets or a dedicated lighting run, not a motor or heavy inductive load.
The 2-pole configuration with neutral conductor switching means both phase and neutral are disconnected when the breaker trips, which is required for single-phase final subcircuits in many IEC-based installations. The B characteristic is the most sensitive common trip curve — it holds for overloads up to about 3× rated current and trips instantaneously above 5×. That makes it suitable for circuits with predominantly resistive loads or where short cable runs keep the impedance low.
Panel integration
The IP20 enclosure is suitable for enclosed panel mounting only — no washdown or outdoor exposure.
