The 70 mm installation depth and 76 mm overall depth fit standard enclosures. Pay attention to polarity on DC: the spec calls out that the power supply position requires polarity consideration. On AC it doesn't matter, but on a DC circuit you need to wire it correctly. The breaker is sealable and touch-protected with IP20 when conductors are connected. No neutral switching on this 2-pole unit — it's a line-side breaker only. This breaker carries the SENTRON brand and is classified under DIN EN 61346-2 and DIN EN 81346-2 as function code F. It's designed to IEC 60947-2 for DC breaking capacity. The surrounding temperature influence is specified: max 95% RH up to 55 °C, derating to max 55% RH at 70 °C and max 35% RH at 75 °C.","metaTitle":"Siemens 5SY5232-7CC11 SENTRON MCB, 2P C 32A DC 440V","metaDescription":"Siemens SENTRON 5SY5232-7CC11 miniature circuit breaker, 2-pole, C-curve, 32A, rated 440V DC / 400V AC, 10kA breaking capacity.
