Its C-curve tripping characteristic suits moderate inrush loads like motor starters and contactor coils, while the 10 kA breaking capacity per EN 60898 handles typical fault levels in 400 V AC distribution. The 2-module-width (36 mm) footprint snaps onto standard DIN rail via the quick-assembly system and accepts any mounting position. ## Key Ratings and What They Mean for Fit Rated 400 V AC with a 10 kA interrupting capacity per EN 60898 — this covers standard industrial fault currents up to that level without cascading upstream. Under UL 1077 and CSA C22.2 No.235, the same breaker is rated 5 kA, so for North American panels the available fault current must be verified against that lower threshold. The C-curve trips magnetically at 5–10× rated current, a good match for motor-starting and transformer inrush where a B-curve would nuisance-trip. Pollution degree 3 and overvoltage category III confirm it for fixed-installation environments with conductive pollution, typical of industrial enclosures. ## Integration and Panel Fit The breaker occupies 2 modular width units (36 mm) on DIN rail. Installation depth is 70 mm; overall depth with terminals is 76 mm. Combined terminals top and bottom accept both busbar and conductor connections, simplifying panel wiring. IP20 with connected conductors means it is protected against finger contact but not washdown — standard for enclosed distribution boards. Sealable allows lockout/tagout compliance. Halogen-free and silicon-free construction matters for sensitive environments like clean rooms or semiconductor fabs where outgassing can contaminate processes. ## Environmental and Compliance Operating temperature range spans -40 °C to 75 °C, covering most outdoor and unconditioned indoor installations. Humidity influence is specified: max 95% RH at 55 °C, derating to 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz, sufficient for machine-mounted panels. Mechanical service life is 10 000 operating cycles typical. Supplementary devices (auxiliary contacts, shunt trips, alarm switches) can be installed, extending the breaker's role in remote monitoring or emergency-stop circuits.","metaTitle":"Siemens 5SY4201-7CC SENTRON MCB, 2-Pole, C-Curve, 10 kA","metaDescription":"Siemens 5SY4201-7CC SENTRON miniature circuit breaker, 2-pole, C-trip characteristic, 10 kA per EN 60898, 400 V AC, IP20.

Both are 2-pole C-curve MCBs with the same 10 kA breaking capacity per EN 60898, but the 5SY4304-7CV carries a higher rated current. Verify the amp rating on your BOM before substituting — the footprint and tripping characteristic are identical, so it drops into the same DIN-rail slot without rewiring if the current matches."},{"question":"Where can I buy 5SY4201-7CC and how is it quoted?","answer":"Sourced and quoted to order against an RFQ through independent industrial-automation distribution.
