What the ratings mean for fit
The Siemens 5SY7532-6 is a 2-pole (1P+N) miniature circuit breaker from the SENTRON series, rated 230 V AC with a B tripping characteristic. The B-curve trips between 3 and 5 times rated current — standard for resistive and lighting loads where inrush is modest. The 15 kA breaking capacity per EN 60898 is the rating for domestic/commercial distribution boards; the 25 kA per IEC 60947-2 is the industrial rating for panelboards with higher available fault current. At DC (72 V max) it interrupts 15 kA per IEC 60947-2, and under UL 1077 / CSA C22.2 No. 235 it is listed at 5 kA — so for North American supplementary protection, keep the fault current below that figure. The 2-module width (36 mm) and 76 mm depth fit standard DIN-rail enclosures; the 70 mm installation depth leaves room for wiring behind the panel.
Deployment context
Snap-on mounting to DIN rail, any position, with quick-assembly system for ganging multiple units. IP20 with connected conductors means it is suited for dry indoor panels — not washdown or outdoor without an enclosure. The combined top and bottom terminals simplify daisy-chaining busbars. Vibration resistance per IEC 60068-2-6 (±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz) qualifies it for machinery panels on conveyors or compressors.
