Any mounting position works, and the installation depth is 70 mm. The 4 A rating holds at 35 °C ambient. At 40 °C it derates to 3.81 A, at 50 °C to 3.61 A, and at 60 °C to 3.39 A. If your panel runs warm — common in a crowded enclosure — size the load against the derated figure, not the 35 °C nameplate.","metaTitle":"Siemens 5SY7304-7 SENTRON MCB, 4A C-Curve 3P 15kA","metaDescription":"Siemens 5SY7304-7 SENTRON miniature circuit breaker, 4A C-curve, 3-pole, 15kA (EN 60898) / 40kA (IEC 60947-2).
