The C-curve holds through 5–10× rated current before instant tripping, so it's the standard pick for mixed resistive-inductive loads in a panel. Mount in any position; quick-assembly fastening snaps onto standard DIN rail. Rated current derates with ambient temperature: 16 A at 35 °C, 14.83 A at 40 °C, down to 12.86 A at 55 °C. Dimensions: 54 mm wide (3 modular units), 90 mm tall, 76 mm deep, with an installation depth of 70 mm behind the panel face. It's IP20 with conductors connected — fine for a dry indoor cabinet, not for washdown zones.","metaTitle":"Siemens 5SY4316-7CV 3-Pole MCB, 16 A, C-Curve, 15 kA","metaDescription":"Siemens 5SY4316-7CV 3-pole MCB, 16 A rated, C tripping characteristic, 15 kA breaking capacity per IEC 60947-2.
