The Siemens Betagard 5SL4232-0RC is a 2-pole miniature circuit breaker with a Z tripping characteristic, rated 32 A at 415 V AC and 50/60 Hz. The 10 kA breaking capacity per EN 60898 (also 10 kA per IEC 60947-2) means it safely clears short-circuit faults up to that level in a 415 V AC system without upstream cascading — sized for sub-distribution boards feeding control cabinets or process instrumentation panels.
Temperature derating — the real current rating changes with ambient
The 32 A rating holds at 50 °C ambient. At 30 °C the breaker carries 35.8 A; at 40 °C it carries 34 A; at 45 °C it carries 33 A; at 55 °C it carries 31 A; at 60 °C it carries 29.9 A.
Mounting and integration — DIN-rail footprint, any position
Mounting position is unrestricted — horizontal, vertical, or inverted — which simplifies layout in tight gland-plate areas. IP20 with connected conductors; degree of pollution 3 and overvoltage category III, so it is rated for fixed-installation distribution boards inside an enclosure.
Vibration resistance tested to IEC 60068-2-6 at 50 m/s² over 25 to 150 Hz. Sealable design allows lockout/tagout in safety circuits.
