It's designed for 50/60 Hz AC systems and carries a pollution degree 3 rating, overvoltage category III — typical for industrial panel distribution in mechanical engineering and industry environments. At 4 A rated, it's sized for a branch circuit feeding a small motor or control transformer, not a main feeder. The 2-pole configuration switches both line and neutral on a single-phase or split-phase circuit. ## Temperature derating — the real-world current Above that, derate linearly: 3.76 A at 40 °C, 3.64 A at 45 °C, 3.5 A at 50 °C, 3.37 A at 55 °C, 3.23 A at 60 °C (–). If your panel ambient runs 50 °C, plan for 3.5 A continuous load max — not the 4 A label. The operating range spans -40 °C to 75 °C (–), with humidity limits up to 95% at 55 °C, tapering to 35% at 75 °C. Width is 36 mm (2 modular units), depth 76 mm, height 90 mm, installation depth 70 mm.","metaTitle":"Siemens SENTRON 5SY4204-7CC11 MCB, 2P C-Curve 4A 10kA","metaDescription":"Siemens SENTRON 5SY4204-7CC11 miniature circuit breaker, 2-pole, C-curve, 4 A rated, 10 kA breaking capacity per EN 60898.

The 5SY4204-7CC11 is a 4 A C-curve unit; the 5SY4140-7 is a 40 A unit. If the panel was wired for a 40 A circuit, dropping in a 4 A breaker would trip immediately on load — the physical fit is fine, but the ampacity mismatch means you'd need to re-evaluate the branch circuit load."},{"question":"What compliance documentation does this brand provide for 5SY4204-7CC11?","answer":"The product is designed per EN 60898, carries pollution degree 3 and overvoltage category III, and is halogen-free and silicon-free.
