The 4-pole (4P) design switches all three phases plus the neutral, though the neutral pole is not switched internally (no neutral conductor switching). Rated at 25 A at both 30 °C and 40 °C (23.79 A at 40 °C per the spec), the breaker derates to 23 A at 45 °C and 21.85 A at 55 °C — a consideration if the panel ambient runs hot. Height is 90 mm. Halogen-free and silicon-free construction meets the material restrictions common in clean manufacturing environments. The 5SL6425-7 carries the SENTRON brand designation. It is classified per EN 61346-2 and IEC 81346-2 as function F (protective device). Energy limitation class 3 indicates it limits let-through energy to a level that protects downstream equipment during a short-circuit event. Touch protection is provided on the terminals.","metaTitle":"Siemens 5SL6425-7 SENTRON MCB, 4P C 25A 6kA 400V","metaDescription":"Siemens 5SL6425-7 SENTRON miniature circuit breaker, 4-pole, C-curve, 25A, 6kA breaking capacity per EN 60898 & IEC 60947-2 at 400V AC.
