Its 4.5 kA breaking capacity per EN 60898 covers residential and light commercial distribution boards where the prospective fault current stays under that threshold — typical for most building infrastructure circuits in the EU and UK. The C-curve means the magnetic trip activates at 5–10× rated current — so this 6 A breaker holds through motor inrush and capacitive loads that would nuisance-trip a B-curve, but clears faster than a D-curve for general-purpose wiring. Rated 400 V AC with a maximum operating voltage of 440 V AC in multi-phase configuration; single-phase circuits are limited to 250 V. The 4.5 kA breaking capacity is the standard domestic rating per EN 60898 — adequate for most final subcircuits in residential and commercial buildings, but verify against the utility's declared fault level at the board. Depth of 76 mm and height of 90 mm mean it fits standard distribution board enclosures with 70 mm installation depth. Mounting position is unrestricted — can be installed horizontally or vertically without derating the thermal trip. Pollution degree 2 covers normal indoor atmospheres with only non-conductive contamination. ## Integration notes Snap-on DIN rail mount, 2 MW width. Accepts auxiliary switches, shunt trips, and undervoltage releases via the accessory slot on the right side. Sealable — the toggle can be locked in the OFF position with a padlock hasp for lockout/tagout.","metaTitle":"5SL3206-7MB SENTRON MCB, 2P C 6A 400V 4.5kA","metaDescription":"Siemens SENTRON 5SL3206-7MB miniature circuit breaker, 2-pole, C-curve, 6A, 400V AC, 4.5kA breaking capacity per EN 60898.
