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.","metaTitle":"SENTRON 5SQ2260-0KA06 2-Pole MCB, B Curve, 6 A, 3 kA","metaDescription":"SENTRON 5SQ2260-0KA06 2-pole miniature circuit breaker, 6 A, B tripping characteristic, 3 kA breaking capacity at 400 V AC.
