The combined terminals at top and bottom accept solid or stranded conductors from 0.75 to 35 mm², with a tightening torque of 2.5 to 3.5 N·m (22 to 31 lbf·in). This range covers everything from control wiring to main feeder cables in a railway auxiliary panel. The product is explicitly designed for railway applications, which means it meets the vibration, temperature cycling, and humidity demands of EN 50155-style environments. The humidity derating curve is specified: max 95% RH up to 55 °C, derating to 55% at 70 °C and 35% at 75 °C. For a cold-chain or refrigeration controls engineer, the -40 °C low end means this breaker runs cold and stays cold in unheated freezer antechambers or outdoor trackside cabinets. Touch protection is integrated, and the sealable design allows tamper-proofing by the panel builder or site electrical engineer. For the MRO storeroom keeper or maintenance-spares purchaser, the 76 mm depth and 36 mm width match the standard SENTRON 5SY5 footprint. If your panel was originally specified with a 5SY5232-6 (32 A, same 2-pole B-curve, same dimensions), the 5SY5216-6CC11 drops in without rewiring — same terminal range, same DIN rail clip, same torque spec. The only difference is the current rating and the DC-only voltage type vs the 5SY5232-6's AC/DC capability.","metaTitle":"Siemens 5SY5216-6CC11 SENTRON MCB, 2P B 16A, 440V DC","metaDescription":"Siemens 5SY5216-6CC11 SENTRON miniature circuit breaker, 2-pole, B-curve, 16 A, 440 V DC, 10 kA IEC 60947-2.
