At 40 °C it derates to 36.96 A; at 50 °C to 33.64 A; at 55 °C to 31.85 A.
Occupies 1 modular width unit (18 mm) on standard DIN rail. Depth is 76 mm, height 90 mm. Installation depth 70 mm. Mounting position any — no derating for horizontal or inverted orientation.
10 kA rated breaking capacity per EN 60898 at 400 V AC. This covers standard residential and light commercial branch circuits.
Both are 1-pole, 1-module-width (18 mm) SENTRON MCBs on the same DIN-rail footprint. The 5SL4140-7CC is rated 40 A versus 6 A for the 5SL4106-7CC — the physical swap is identical, but the circuit conductors and upstream protection must be sized for the higher 40 A rating.
The MCB carries EN 60898 certification for breaking capacity. It is rated for overvoltage category III, pollution degree 2, and vibration resistance per IEC 60068-2-6. Halogen-free and silicon-free construction.
