The C-curve means it tolerates inrush currents 5–10 times the rated current before tripping magnetically — the standard choice for mixed resistive and moderate inductive loads like small motor circuits, lighting banks, and general distribution in residential and light commercial infrastructure. The 7.5 kA breaking capacity at 415 V AC is the fault current it can safely interrupt under EN 60898; for most domestic and light commercial installations this is sufficient, but verify your prospective short-circuit current (PSCC) at the point of installation. ## Panel integration and mounting The 5SL6320-7RC occupies 3 modular-width units (54 mm total width) on a standard DIN rail. Depth is 76 mm, installation depth 70 mm — it sits flush with adjacent devices in a populated enclosure. Mounting position is any, which simplifies layout in tight cabinets. The IP20 rating applies with connected conductors, so it is intended for installation inside a panel or distribution board, not in wet or washdown areas. ## Environmental and compliance notes Halogen-free and silicon-free construction — relevant for installations with sensitive contacts or where low-smoke, zero-halogen cabling is specified. The operating temperature range spans -40 °C to 75 °C, covering most indoor and sheltered outdoor enclosures. Overvoltage category III and pollution degree 2 are standard for fixed-installation MCBs in distribution boards.","metaTitle":"Siemens 5SL6320-7RC SENTRON MCB, 20 A, 3-Pole, C-Curve, 7.5","metaDescription":"Siemens 5SL6320-7RC SENTRON miniature circuit breaker, 20 A, 3-pole, C characteristic, 7.5 kA breaking capacity per EN 60898.
