Under UL 1077 and CSA C22.2 No. 235 it carries 5 kA. The 18 mm width (1 modular unit) and 76 mm depth let it drop into a standard DIN-rail enclosure alongside other SENTRON breakers. Mounting position is any; the quick-assembly system clips onto the rail without tools. Rated to IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 and CSA C22.2 No. 235. That dual standard coverage means it's accepted in both IEC (CE-mark) and North American (UL/CSA) jurisdictions — one part number for global machine builds.","metaTitle":"Siemens 5SY4140-7 SENTRON MCB, 1P C-curve 10kA/15kA, 18mm","metaDescription":"Siemens 5SY4140-7 SENTRON miniature circuit breaker, 1-pole C-curve, 10 kA per EN 60898-1 / 15 kA per IEC 60947-2.
