The Siemens 5SN6201-7CP is a 2-pole miniature circuit breaker from the SENTRON 5SN series, rated for 400 V AC at 50 Hz. Its interrupting capacity is 6 kA per EN 60898 for standard branch-circuit protection, and 30 kA per IEC 60947-2 for industrial panel coordination — the 30 kA figure is the one that governs SCCR headroom in a distribution board with upstream transformer capacity. On the DC side, it handles up to 72 V, which covers 48 V control loops and some 60 V battery banks, but not 110 V DC telecom plants.
No official successor has been issued. If a direct cross-reference is needed for a second-source gate, the SENTRON 5SY7206-7CC shares the same 2-pole, 400 V AC, 30 kA (IEC 60947-2) footprint and 2-MWU width — the difference is in the tripping characteristic curve and auxiliary accessory compatibility, not the basic fit.
Integration Notes
Accepts solid conductors up to 35 mm² at the terminals.
