The SENTRON 5SY6016-6KV is a B-curve miniature circuit breaker, 1+N-pole, rated 16 A with a 6 kA breaking capacity at 230 V AC. The 1+N configuration switches both phase and neutral, which means the neutral is isolated when the breaker is off — a requirement in many single-phase distribution boards for safe isolation.
Environmental and installation notes
Rated for periodic exposure up to +55 °C and 95% humidity, so it's fine in non-conditioned enclosures or outdoor-rated panels as long as condensation doesn't pool. The 70 mm depth fits standard SENTRON distribution boards and most DIN-rail enclosures — no panel rework needed for a swap-in.
