Product details

Mounting and integration — 1 MW per DIN slot

Terminal capacity accepts 0.75 to 35 mm² solid or stranded copper, torqued to 2.5–3.5 N·m (22–31 lbf·in). Polarity must be observed on the DC supply; the breaker is marked accordingly. Sealable with a lead seal for tamper-proofing in metered or safety-critical branches.

Environmental and compliance — railway-grade endurance

Humidity derating: 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C. Halogen-free and silicon-free.

Listed as current production (active lifecycle stage). No official successor or alternate MPN is listed — this remains the current catalog number for DC railway MCB applications in the SENTRON 5SY series.

Frequently asked questions

Will 5SY5102-6CC11 drop into a panel specified around 5SY3132-6 without rewiring?

Mechanically yes — both share the same 18 mm width, 70 mm installation depth, DIN-rail quick-assembly mounting, and 0.75–35 mm² terminal capacity. The critical difference is voltage: 5SY5102-6CC11 is a DC-rated breaker (220 V DC / 250 V DC max) for railway use, while 5SY3132-6 is an AC-rated breaker (400 V AC, 72 V DC max). Swapping them without verifying the circuit voltage and interrupting rating would be unsafe.
