The Siemens SENTRON 5SL6410-6 is a 4-pole miniature circuit breaker (MCB) from the 5SL6 design family, rated 10 A at 400 V AC with a B tripping characteristic.
Snap-on DIN rail mounting; the 4-pole body occupies 4 width units (72 mm wide). Conductor range 0.75 mm² to 25 mm², accepting solid or stranded copper. Mounting position is unrestricted; the design is halogen-free and silicon-free, and the enclosure is sealable. These matter for panels in clean-room or coated-board environments where outgassing or tamper evidence is specified.
