The 25 A rating at 230 V AC gives a maximum switched power of roughly 5.75 kW for single-phase loads; the 1 MW figure in the description likely reflects a per-pole or system-level labeling convention, not a continuous load limit — size your downstream load to the 25 A continuous rating. The B characteristic means magnetic trip occurs at 3–5× In (75–125 A), so it avoids nuisance trips on capacitor-switching or motor-start inrush but clears fast on a hard short. Terminals accept solid or stranded conductors from 0.75 to 16 mm², with a tightening torque of 2.0–2.5 N·m (17.7–22.1 lbf·in). The 1P+N configuration switches both phase and neutral, with neutral switching confirmed as a product function — important for applications requiring disconnection of the neutral conductor. Ambient temperature range is -25 to +45 °C, with periodic excursions to +55 °C at 95% humidity; derate the continuous current if the enclosure ambient exceeds 45 °C per the manufacturer's thermal curve.","metaTitle":"Siemens 5SY6025-6 SENTRON MCB, 1P+N, B-25A, 6kA","metaDescription":"Siemens 5SY6025-6 SENTRON miniature circuit breaker, 1P+N, B-curve 25 A, 6 kA per EN 60898.
