Rated for any mounting position, so it works in vertical busway or horizontal sub-panels. The neutral conductor is switched, which matters for IT or corner-grounded delta systems where you need to isolate both poles. The sealable design allows a lockout tagout (LOTO) staple through the toggle — a common plant-safety requirement. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, so it holds up on conveyor drives or compressor skids. Supplementary devices (undervoltage release, shunt trip, auxiliary contacts) can be snapped onto the right side. Halogen-free and silicon-free construction meets clean-room and rail-vehicle material restrictions. Approvals cover IEC/EN 60898-1 (household-type MCB), IEC/EN 60947-2 (industrial MCB), UL 1077 (supplementary protector), and CSA C22.2 No. 235. The 5 kA UL 1077 rating is lower than the IEC 60947-2 figure — that's normal for UL supplementary protectors, which don't carry the same SCCR as a full UL 489 breaker. For a UL 508A panel, verify the SCCR coordination with the upstream feeder breaker.","metaTitle":"Siemens 5SY6514-7 SENTRON MCB, 2-pole C-curve, 6/30 kA","metaDescription":"Siemens 5SY6514-7 SENTRON miniature circuit breaker, 2-pole 1P+N, C characteristic, 6 kA per EN 60898 / 30 kA per IEC 60947-2.

It shares the same C-curve and 6/30 kA breaking capacities, but the 5SY6514-7 switches the neutral pole, so it replaces a 2-pole 1P+N breaker.
