The C-curve (tripping between 5× and 10× In) is the standard choice for general-purpose loads: lighting, socket circuits, small motor starters, and distribution subfeeds where inrush isn't extreme. The 6 kA rating at 400 V AC means it safely interrupts a fault up to that level without upstream damage — adequate for most residential and light commercial panelboards. Rated for 50/60 Hz, overvoltage category III, pollution degree 2. ## Panel fit and mounting Snaps onto standard DIN rail, any mounting position. Occupies 2 modular width units (36 mm wide), with a depth of 76 mm and 70 mm installation depth behind the panel. IP20 with connected conductors — fine for enclosed distribution boards; not rated for washdown or outdoor exposure. Sealable (padlockable) for lockout/tagout. Halogen-free and silicon-free construction, so it won't outgas corrosive compounds in sensitive environments.","metaTitle":"Siemens 5SL6240-7 SENTRON MCB, 2-pole C-curve 40A 6kA","metaDescription":"Siemens 5SL6240-7 SENTRON miniature circuit breaker, 2-pole, C-curve, 40 A, 6 kA breaking capacity per EN 60898.
