Siemens 5SY6215-8CC — SENTRON 2-Pole D-Curve MCB, 1.6 A
The Siemens 5SY6215-8CC is a 2-pole miniature circuit breaker from the SENTRON 5SY6CC series, rated at 1.6 A with a D tripping characteristic and a rated voltage of 400 V AC. The 1.6 A rating means it's sized for smaller auxiliary circuits, not main feeder protection. Breaking capacity is 6 kA per EN 60898 at 400 V AC, with a 5 kA rating under UL 1077 / CSA C22.2 No. 235 for North American installations. That's adequate for most industrial panel secondary circuits where the upstream fault current is limited.
For buyers maintaining a BOM freeze, this part is a stable line item. If a second-source or alternate form factor is ever needed, the SENTRON 5SY series includes several 2-pole D-curve variants at different current ratings — but the 5SY6215-8CC itself is the 1.6 A code in the 5SY6CC design.
Integration — panel fit and wiring
Overall dimensions: 90 mm height, 76 mm depth. Terminals accept solid or stranded conductors from 0.75 to 35 mm², with a tightening torque range of 2.5 to 3.5 N·m. Both top and bottom terminals are combined (phase + neutral busbar compatible), though the unit does not switch the neutral — it's a 2-pole MCB protecting both phase conductors in a single-phase or split-phase circuit.
Humidity tolerance: max 95% at 55 °C, derating to 55% at 70 °C and 35% at 75 °C. The unit is sealable (tamper-evident provision) and carries touch protection per the product feature. Mounting position is any orientation; supply cord entry can be from top or bottom (any position). Rated frequency 50/60 Hz.
