Product details

Siemens 5SY4140-7 SENTRON MCB — 1-pole C-curve, 10/15 kA breaking capacity

Breaking capacity is rated 10 kA per IEC/EN 60898-1 and 15 kA per IEC 60947-2, with a DC rating of 15 kA at 60 V (max 72 V) per IEC 60947-2. 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.
