The Siemens 5SY7532-7CC is a SENTRON miniature circuit breaker (MCB) with a 1-pole-plus-neutral (1P+N) design, meaning it switches both line and neutral but only protects the line conductor against overcurrent. Its headline breaking capacity is 25 kA per IEC 60947-2 at 230 V AC, which puts it in the high-interrupting range for a 2-MW-wide MCB. For UL 1077 / CSA C22.2 No. 235 listed applications, the interrupting rating is 5 kA.
The 5SY7532-7CC snaps onto a standard DIN rail (quick assembly system per the spec) and occupies 2 modular width units (36 mm total). Depth is 76 mm, installation depth 70 mm — typical for SENTRON 5SY series breakers, so it fits existing distribution boards without a panel rework. Degree of protection is IP20 with conductors connected — standard for enclosed panelboard use, not for wet or washdown environments.
Operating temperature range spans -40 °C to 75 °C, with humidity derating above 55 °C. Suitable for mechanical engineering and industrial environments per the manufacturer's designation.
