It's a 1P+N (switched neutral) unit in a 36 mm wide, 2-module-width housing — that's two standard DIN-rail slots. Current-production part, so no last-time-buy scramble. At 0.3 A, this is a low-current branch; you'd see it on a control transformer secondary, a PLC power supply feed, or a signal-conditioner loop. Derate the 0.3 A rating at elevated ambient: 0.28 A at 40 °C, 0.25 A at 55 °C — factor that into your wire sizing if the breaker lives in a warm enclosure. The 1P+N configuration switches both phase and neutral, with the neutral pole opening after the phase pole — important for isolation on single-phase circuits where you want guaranteed disconnection of both conductors. The neutral conductor switching feature is built in, so no separate neutral disconnect block needed. Touch protection is integral; The 10,000 typical mechanical operating cycles is the expected life under normal switching; this isn't a daily-switch-duty device, but it'll handle occasional manual operation for decades.","metaTitle":"Siemens 5SL6514-7 SENTRON MCB, 1P+N, C-curve, 0.3 A, 6 kA","metaDescription":"Siemens 5SL6514-7 SENTRON miniature circuit breaker, 1P+N, C-curve, 0.3 A, 6 kA breaking capacity per EN 60898.

Availability and current pricing are confirmed at quote time — submit an inquiry for a firm quote."},{"question":"What is the 5SL6514-7's width and depth for panel layout?","answer":"The 5SL6514-7 is 36 mm wide (2 modular width units) and 76 mm deep. Installation depth is 70 mm. It fits any standard DIN-rail enclosure with those clearances."},{"question":"Will the 5SL6514-7 drop into a panel specified for the 5SL6550-7BB?","answer":"Both are 1P+N, 2-MW SENTRON MCBs on the same DIN-rail footprint, so mechanical fit is identical. The difference is the rating: 5SL6514-7 is 0.3 A C-curve; 5SL6550-7BB is a different current rating. No rewiring needed if the current matches your circuit."},{"question":"What compliance documentation does Siemens provide for the 5SL6514-7?","answer":"The 5SL6514-7 is designed to EN 60898 and IEC 60947-2, with a 6 kA breaking capacity under both standards. It's halogen-free and silicon-free.
