The Siemens SENTRON 5SY7615-7 is a 4-pole miniature circuit breaker (3P+N) with C-curve tripping characteristic, rated 1.6 A at 400 V AC. It is listed as current production (lifecycle stage: current) and is sourced to order. Breaking capacity is 15 kA per EN 60898 and 50 kA per IEC 60947-2 — the higher IEC figure means this breaker coordinates with downstream devices in an industrial panel where fault current can exceed 15 kA. Rated for overvoltage category III, so it's suited for fixed-installation distribution boards — not just final circuits. Ambient temperature range -40 to +70 °C covers unheated enclosures and hot panel interiors.
Width is 72 mm (4 width units), installation depth 70 mm. Mounting position any — no derating required for horizontal orientation. Quick-assembly system snaps onto standard DIN rail. Combined terminal top and bottom — feed from either direction, no special busbar position. Sealable for LOTO lockout; touch protection IP20 with conductors connected. Halogen-free and silicon-free construction matters in clean-room or food-bev environments where outgassing can contaminate product or corrode contacts.
Coordination and selectivity
The C-curve (5-10× In) is standard for motor starters and transformer primaries — not for lighting or resistive loads where B-curve would trip faster. DC rating: 72 V maximum, 15 kA per IEC 60947-2. If your DC bus runs above 72 V, this breaker is not the right choice — step up to the 5SY7 DC-rated variants or a UL 489 listed DC breaker.
Lifecycle stage is current.
