Width is 36 mm (2 modular units), depth 76 mm, height 90 mm, with an installation depth of 70 mm. That matches the standard 18 mm/module DIN-rail footprint — drops into any SENTRON or generic distribution board without extra adaptors. Screwless outgoing terminals speed wiring; touch protection is built in. ## DC rating and application notes Rated for DC operation up to 60 V maximum — useful for control-circuit protection or DC distribution in telecom shelters. Mechanical service life is 20 000 cycles typical. Mounting position is unrestricted. No neutral conductor switching on this 2P variant.","metaTitle":"Siemens 5SJ6216-6KS SENTRON MCB, 2P B 16A 6kA, 400V AC","metaDescription":"Siemens SENTRON 5SJ6216-6KS miniature circuit breaker, 2-pole, B-curve, 16 A, 6 kA breaking capacity per EN 60898/IEC 60947-2.
