The 4-pole format (3 phases + switched neutral) suits three-phase distribution panels where the neutral needs to be switched with the phases, common in European and IEC-style industrial switchgear. The headline 25 A rating holds at 35 °C ambient. Above that, the breaker derates linearly: 23.18 A at 40 °C, 22.2 A at 45 °C, 21.2 A at 50 °C, and 20.1 A at 55 °C. If your panel runs warm — and most closed industrial enclosures do — size the continuous load against the derated figure, not the 25 A nameplate. Vibration resistance per IEC 60068-2-6 (±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz) confirms it holds calibration under pump or compressor vibration — not just a static panel mount. The 4-module width (72 mm) matches the standard 18 mm per pole footprint. Any mounting position is allowed, which simplifies layout in crowded enclosures. Ambient temperature range spans -40 °C to 75 °C, with humidity limits: max 95% RH up to 55 °C, derating to 35% RH at 75 °C. The standard cited is IEC / EN 60947-2, the harmonized European standard for low-voltage switchgear and controlgear circuit breakers.","metaTitle":"Siemens 5SY4625-7CV MCB, 4-Pole C-Curve 25 A, 15 kA IEC 6094","metaDescription":"Siemens 5SY4625-7CV 4-pole miniature circuit breaker, C-curve 25 A, 15 kA breaking capacity per IEC 60947-2.
