The 25 A rating governs the continuous load it can carry in a 40 °C ambient — derate for higher panel temperatures. The 2-pole construction switches both live conductors in a single-phase circuit or one pole of a two-phase system. The 60 V DC maximum applies when used in DC circuits — the DC arc extinguishes differently, so the rating is lower than the AC figure. The 70 mm installation depth is standard for the 5SJ6 family — it fits any DIN-rail enclosure that accepts modular devices. The -40 °C to +75 °C storage range covers cold warehouses and hot shipping containers, but the operating ambient is constrained by the surrounding temperature influence — periodically up to +55 °C with 95 % humidity. The 2-module width occupies 36 mm of rail space — factor that into your enclosure fill calculations. The sealable design allows a lead seal or a lockout tag to be fitted, which matters for revenue-metering applications or lockout/tagout procedures. The touch protection is built into the terminals; no additional finger guards are needed inside a closed panel.","metaTitle":"Siemens 5SJ6225-7 SENTRON MCB, 2-Pole C-Curve 25A 6kA","metaDescription":"Siemens 5SJ6225-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 25 A, 400 V AC, 6 kA breaking capacity per EN 60898.
