It delivers a 25 kA breaking capacity per IEC 60947-2 — sufficient for high-fault-current industrial panels where coordination with upstream switchgear is critical. Under UL 1077 and CSA C22.2 No. 235, the interrupting rating is 5 kA, so verify the available fault current at the point of installation when specifying for North American projects. ## Mounting & Integration Snaps onto DIN rail via the quick-assembly system, occupying 3 modular width units. Mounting position is any orientation; installation depth is 70 mm. The housing is IP20 with connected conductors — suitable for enclosed distribution boards and control panels where the front face is not exposed to washdown or dust ingress. Combined terminals top and bottom simplify busbar and outgoing cable routing. ## Environmental & Compliance Rated for ambient temperatures from -40 °C to +75 °C. Halogen-free and silicon-free construction — relevant for clean-room or corrosive-environment installations where outgassing must be minimized. Overvoltage category III, pollution degree 3. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Sealable for tamper-proof applications.","metaTitle":"Siemens 5SY7320-7CC SENTRON MCB, 20 A, 3-Pole, C-Curve, 25 k","metaDescription":"Siemens SENTRON 5SY7320-7CC miniature circuit breaker, 20 A, 3-pole, C-curve, 25 kA IEC breaking capacity.

The 5SY7320-7CC is a 20 A C-curve; the 5SY7210-7CC is a 10 A C-curve.
