The Siemens 5SL6316-6RC is a SENTRON 5SL6 miniature circuit breaker rated 16 A at 415 V AC, 3-pole, with a B tripping characteristic and a 7.5 kA breaking capacity per EN 60898.
Three width units (54 mm wide) snap onto standard DIN rail; the 76 mm depth and 70 mm installation depth leave room for cable management in a shallow enclosure. Screw terminals accept 0.75 to 25 mm² solid or stranded copper — sized for the 16 A feed-through without pigtail adapters. Tightening torque range is 2.5 to 3 N·m, consistent with panel-builder practice for this conductor class.
