Rated for 400 V AC phase-to-phase (max 440 V in multi-phase operation), 50 Hz supply. Any mounting position is allowed, which simplifies layout in crowded enclosures. ## Terminal and environmental specs Tightening torque range is 2.5 to 3 N·m — consistent with standard comb busbar systems. Touch protection is built in (IP20 with connected conductors), and the breaker is sealable for anti-tamper applications. Rated ambient temperature -25 to +45 °C; storage range -40 to +75 °C. Withstands periodic 55 °C at up to 95% humidity. Energy limiting class 3, overvoltage category 3. No neutral conductor switching (2-pole unit switches both phases but does not break the neutral — verify your system neutral arrangement). DC rated maximum 60 V.","metaTitle":"Siemens 5SL6216-6BB SENTRON MCB, 16 A, B-Curve, 2-Pole, 6 kA","metaDescription":"Siemens 5SL6216-6BB SENTRON miniature circuit breaker, 16 A rated, B tripping characteristic, 2-pole, 6 kA breaking capacity per EN 60898/IEC 60947-2.
