The Siemens SENTRON 5SL6240-7RC is a 2-pole miniature circuit breaker rated 40 A with a C tripping characteristic, breaking 7.5 kA per EN 60898. That C-curve means it handles moderate inrush — think motor starters, pump contactors, or a bank of lighting ballasts — without nuisance tripping on the magnetizing spike, but it still clears a hard fault fast enough to protect the downstream wiring.
The 72 V DC maximum rating covers control-circuit applications off a rectified supply.
Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
Rated 7.5 kA according to EN 60898 at 400/415 V AC.
The 5SL6240-7RC is 36 mm wide (2 MW units) versus 18 mm (1 MW) for the 5SL4106-7CC, so it takes one extra slot on the DIN rail. Depth and height are identical at 76 mm and 90 mm, so the enclosure depth and cover clearance are the same.
