Siemens SENTRON 5SY6232-7CC — 2-pole C-curve MCB, 32 A, 6 kA
It's a 2-pole unit with a C-curve tripping characteristic, rated 32 A at 40 °C and 6 kA breaking capacity per EN 60898.
Sizing and thermal derating — what the 32 A rating really means
The 32 A rating holds at 35 °C ambient. At 40 °C it derates to 30.08 A; at 45 °C to 29.09 A; at 50 °C to 28.03 A; at 55 °C to 26.94 A. Plan your load accordingly, especially if you're pushing continuous current near the mark. The operating temperature range is -40 to 75 °C, with humidity limits: max 95% up to 55 °C, then derating to 55% at 70 °C and 35% at 75 °C. That's typical for an indoor industrial MCB — no outdoor or condensation-heavy duty without a weatherproof enclosure.
Mounting position any — no derating for sideways or upside-down install. Combined terminals top and bottom, sealable if the panel requires padlocking. Neutral conductor switching is not provided — this is a 2-pole breaker switching both phases, not a 1P+N configuration. The design of pole is 2P, so it's for two live conductors, not a switched neutral.
