It occupies 3 modular width units (54 mm) on a DIN rail and accepts supplementary devices like shunt trips or auxiliary contacts. The 5.1 W power loss per pole at rated current in hot operating state is the figure to check for thermal coordination inside a crowded enclosure. Rated for residential buildings and infrastructure, it handles multi-phase AC circuits up to 440 V and DC circuits up to 72 V. The C-curve trips between 5 and 10 times rated current, making it the standard choice for motor-starting and moderate inrush loads in distribution boards. ## Mounting and integration Mounts on DIN rail in any position, with an installation depth of 70 mm and overall depth of 76 mm. The IP20 rating applies with connected conductors — standard for enclosed distribution panels. Pollution degree 2 and overvoltage category III cover fixed-installation environments. The housing is halogen-free and silicon-free, which matters for clean-room or corrosive-gas applications. ## Environmental and compliance Operates from -40 °C to 75 °C, with vibration resistance of 50 m/s² at 25 to 150 Hz per IEC 60068-2-6. The sealable design allows tamper-proofing in metered or secured installations.","metaTitle":"Siemens 5SL6340-7CC SENTRON MCB, 3P C-curve 40 A 6 kA","metaDescription":"Siemens 5SL6340-7CC SENTRON miniature circuit breaker, 3-pole, C-curve, 40 A, 6 kA per EN 60898, 400 V AC.
