The Siemens SENTRON 5SQ2570-2YA06 is a 2-pole miniature circuit breaker rated 6 A with a C-curve tripping characteristic, designed for 400 V AC circuits at 50 Hz. This is a 1P+N configuration (2 poles total) with integrated neutral conductor switching, meaning the neutral is disconnected when the breaker trips — a requirement in some regional wiring codes for final circuits where the neutral must be switched alongside the phase.
IP20 finger-safe terminals suit enclosed distribution boards. Overvoltage category 3 and energy limiting class 3 place it in the standard selectivity band for downstream final circuits.
