Three poles, no neutral switching, so it's a straight 3P device for a three-phase line. The 6 kA breaking capacity per EN 60898 (5 kA per UL 1077) is the fault current it can safely interrupt at 400 V AC — right-sized for most industrial panel sub-feeders where the prospective short-circuit current stays under that level. Rated for 400 V AC (440 V max in multi- or single-phase operation), and it handles 50/60 Hz supply. The DC rating tops out at 72 V. Mechanical service life is 10 000 operating cycles typical, and the 1.2 W power loss per pole at rated current in hot operating state is low enough that you don't need to de-rate adjacent devices in a crowded DIN-rail enclosure. Mounting position is any orientation. The 3 modular width units (54 mm total) match the standard SENTRON footprint, and the installation depth is 70 mm behind the panel face (76 mm overall depth).","metaTitle":"Siemens 5SY6302-7CC SENTRON MCB, 3P C-Curve, 6 kA","metaDescription":"Siemens 5SY6302-7CC SENTRON miniature circuit breaker, 3-pole, C characteristic, 6 kA per EN 60898, 400 V AC.
