The 32 A rating at 35 °C ambient derates to 29.66 A at 40 °C and 27.1 A at 50 °C, so if the breaker lives in a warm enclosure or next to other heat sources, factor in the thermal derating rather than relying on the 32 A nameplate. The 5SY7332-7CC occupies 3 modular width units (54 mm wide) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It mounts in any position and uses a quick-assembly system for snap-on installation — no tools needed to clip it onto the rail. Combined terminals at both top and bottom accept a range of conductor sizes, and the touch-protection feature meets the requirements for safe operation without accidental contact.","metaTitle":"Siemens SENTRON 5SY7332-7CC MCB, 3P, 32 A, C-Curve, 25 kA","metaDescription":"Siemens SENTRON 5SY7332-7CC miniature circuit breaker, 3-pole, 32 A, C tripping characteristic, 25 kA breaking capacity per IEC 60947-2.
