The Siemens Betagard 5SL4325-0RC is a 3-pole miniature circuit breaker rated 25 A at 415 V AC, with a 10 kA breaking capacity certified to both IEC 60947-2 and EN 60898. The Z tripping characteristic is the key differentiator here — it triggers between 2 and 3 times rated current, much tighter than a B (3-5x) or C (5-10x) curve. That makes it the right choice for protecting semiconductor circuits, control transformers, or sensitive electronics where the inrush isn't high but you need fast clearing on a fault. The 25 A AC rating at 30 °C derates to 23.4 A at 60 °C, so if the panel runs hot, factor that in.
Fit and integration — 3 MW, IP20, DIN rail
Halogen-free and silicon-free construction. Vibration resistance rated at 50 m/s² over 25 to 150 Hz per IEC 60068-2-6. The part carries the usual Siemens Betagard compliance suite — RoHS, REACH, CE, and UL/CSA certifications are standard for this series; specific certification documents are available on request.
