The 10 kA breaking capacity at 400 V AC per EN 60898 means it can safely interrupt a fault current up to that level without welding its contacts or cascading failure upstream — that's the standard for most European industrial sub-distribution. For UL 1077 supplementary protection applications, it's rated 5 kA. This MCB occupies 4 width units (72 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. The quick-assembly mounting system snaps onto the rail without tools. Terminals accept solid or stranded conductors from 0.75 to 35 mm², with a tightening torque of 2.5 to 3.5 N·m — standard for a 63 A frame, so the 2 A rating doesn't mean small terminals. ## Construction details Sealable with a padlock or tagout hasp for lockout/tagout procedures. Touch protection on the terminals is built in. Energy limiting class 3 means it limits let-through energy well, reducing stress on downstream equipment during a fault.","metaTitle":"Siemens 5SY4402-7CC SENTRON MCB, 4P C 2A 10kA","metaDescription":"Siemens 5SY4402-7CC SENTRON miniature circuit breaker, 4-pole, C-curve, 2 A rated current, 10 kA breaking capacity per EN 60898.
