Breaking capacity is 15 kA per EN 60898 and 50 kA per IEC 60947-2, giving solid fault-clearing headroom for industrial panel distribution. Also carries a 5 kA rating under UL 1077 and CSA C22.2 No. 235 for North American acceptance. Mounts via quick-assembly system (DIN rail) in any position, with an installation depth of 70 mm and overall dimensions 72 mm wide × 90 mm high × 76 mm deep. Terminal capacity accepts solid or stranded conductors from 0.75 to 35 mm², with combined top and bottom terminals. IP20 with conductors connected. Halogen-free and silicon-free construction suits clean-room or sensitive electronic environments. Ambient temperature range -40 to +70 °C (operating), with humidity derating above 55 °C. Sealable for tamper-proof installations. Touch-protected design.","metaTitle":"Siemens SENTRON 5SY7614-8 MCB, 4-pole D-curve 0.3 A, 15 kA","metaDescription":"Siemens SENTRON 5SY7614-8 miniature circuit breaker, 4-pole (3P+N), D tripping characteristic, 0.3 A rated current, 15 kA breaking capacity per EN 60898, 50 kA per IEC 60947-2.
