It's designed for 400 V AC nominal, with a maximum of 440 V in multi-phase operation. The neutral pole is switched, making it a true 3P+N device for single-phase or three-phase branch circuits where you need the neutral protected. Lifecycle status is marked as current production — no phase-out or NRND flags on this order code. That means it's still a standard catalog item from Siemens, not something you need to chase as surplus. Terminal screws need 2.5 to 3 N·m, and the wire range accepts 0.75 to 25 mm² solid or stranded. IP20 with conductors connected, so it's panel-internal only — no washdown exposure. Ambient range is -25 to +45 °C, with periodic excursions to +55 °C and 95% humidity. Rated for residential and infrastructure use per the manufacturer's suitability listing. Overvoltage category 3, energy limiting class 3. Halogen-free and silicon-free construction. Sealable for tamper evidence. Touch protection is built in.","metaTitle":"Siemens 5SL6614-7 SENTRON MCB, 4-pole C-curve 0.3 A 6 kA","metaDescription":"Siemens 5SL6614-7 SENTRON miniature circuit breaker, 4-pole (3P+N), C-curve, 0.3 A rated, 6 kA breaking capacity per EN 60898 & IEC 60947-2, 400 V AC.
