Breaking capacity is 25 kA per EN 60898, which gives solid headroom for high-fault installations like meter panels or distribution boards close to the transformer. The 1.5-module-width body (about 27 mm) fits standard DIN-rail enclosures, and the busbar fastening method (DIN 43870 Part 2) means it clips directly onto a 40-mm busbar system without extra brackets. The 16 A rating holds at 30 °C ambient; at 40 °C it derates to 15.2 A, at 50 °C to 14.4 A. Terminals accept 2.5 to 50 mm² solid or stranded copper — that covers everything from 14 AWG to 1/0 AWG, so it handles both branch-circuit and feeder-size conductors. Mounts on a 40-mm busbar system per DIN 43870 Part 2, or on standard DIN rail via the busbar fastening method. The 1.5-module width saves panel space compared to a 2-module breaker — useful when packing multiple circuits into a meter cabinet. Infeed is at the box terminal (bottom), which is the conventional arrangement for meter-panel wiring. Sealable design (yes) allows the utility to lock the cover after installation, meeting common revenue-meter security requirements.","metaTitle":"Siemens 5SP3716-2 SENTRON MCB, 1P 16A E-Curve 25kA","metaDescription":"Siemens 5SP3716-2 SENTRON miniature circuit breaker, 1-pole 16 A, E tripping characteristic, 25 kA breaking capacity at 230 V AC.
