The Siemens 5SJ6206-7 is a 2-pole miniature circuit breaker from the SENTRON 5SJ6 series, rated 6 A at 400 V AC with a C tripping characteristic. At 6 A per pole, it protects branch circuits on 400 V three-phase or split-phase panels running at 50 Hz. The 70 mm installation depth and 2 width units fit standard DIN rail.
Snap-on DIN rail mount, any orientation. The 70 mm depth fits standard enclosures.
Mechanical endurance
Rated for 20 000 mechanical switching cycles typical. That's a solid figure for a panelboard MCB — it handles routine isolation and infrequent fault clearing without premature wear. The 6 kA breaking capacity (per EN 60898 and IEC 60947-2 on the sibling 5SJ6220-6) is standard for this class; the 5SJ6206-7 shares the same 5SJ6 platform design.
