The B characteristic means it trips between 3 and 5 times rated current — suited for resistive or general-purpose loads where inrush is low, like lighting or control transformers in a refrigeration panel. The 2-pole form factor (2 modular width units, 36 mm wide) protects both line and neutral on single-phase circuits, or one pole per phase on DC. Rated for universal current (AC/DC) and designed for railway applications per the evidence, this breaker carries an ambient temperature range from -40 °C to 75 °C, which means it runs cold and stays cold — no derating drama in a freezer warehouse or an unheated equipment shed. The IP20 rating with connected conductors is standard for enclosed panel mounting; the sealable design (yes) lets you lock the toggle to prevent tampering on critical circuits. ## Mounting and integration Snaps onto a standard DIN rail via the quick assembly system; mounting position is any, so vertical or horizontal panel layouts work. Installation depth is 70 mm, overall depth 76 mm — check gland-plate clearance if the enclosure is shallow. Combined terminals top and bottom accept copper conductors; the fastening method is tool-less snap-on, which cuts panel build time.","metaTitle":"Siemens 5SY5210-6KK11 SENTRON MCB, B Curve, 10A, 2-Pole, 10k","metaDescription":"Siemens 5SY5210-6KK11 SENTRON miniature circuit breaker, B characteristic, 10A rated, 2-pole, 10kA breaking capacity per EN 60898.
