At 18 mm wide (1 width unit) and 76 mm deep, the 5SL3163-6 occupies a single module on a DIN rail, with 70 mm installation depth required behind the panel surface. The screw terminals accept solid or stranded conductors from 0.75 mm² up to 25 mm², with a tightening torque of 2.5 to 3 N·m.
The 5SL3163-6 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
Both are 1-pole SENTRON 5SL3 breakers with the same 18 mm width, DIN-rail mounting, and screw-terminal conductor range (0.75–25 mm² solid/stranded). The 5SL3163-6 is rated 63 A versus 20 A for the 5SL3120-6MB, so the physical swap is straightforward, but the circuit must be rated for the higher current. The B tripping characteristic is shared.
The 5SL3163-6 carries breaking capacity certifications to EN 60898 and IEC 60947-2. It is halogen-free and silicon-free. For specific RoHS, REACH, or UL documentation, request the manufacturer's declaration of conformity with your RFQ.
