The 10 kA breaking capacity at 400 V AC (per EN 60898) tells you this breaker can safely interrupt a fault current up to that level without upstream damage, which is the minimum for most residential and light commercial distribution boards. The 400 V AC rated voltage (440 V max multi-phase) covers three-phase supply up to 400/440 V line-to-line. The rated frequency is 50 Hz, matching standard European mains. This breaker snaps onto a standard 35 mm DIN rail, occupying 3 width units (roughly 54 mm on the rail). The overall dimensions are 90 mm height, 54 mm width, and 76 mm depth, with an installation depth of 70 mm — so it fits in most standard enclosures without protruding. Wire terminals accept 0.75 mm² to 25 mm², solid or stranded, and the unit is sealable to prevent tampering after commissioning. The overvoltage category 3 means it is designed for fixed installation with transient overvoltages up to 4 kV, typical for distribution boards. The energy limiting class 3 indicates it limits the let-through energy effectively, reducing stress on downstream wiring. The product is designed for residential buildings and infrastructure applications. The manufacturer provides compliance documentation including RoHS, REACH, and UL/IEC declarations as part of the standard product documentation package. The unit carries touch protection (finger-safe terminals) and is vibration resistant to 50 m/s² at 25 to 150 Hz per IEC 60068-2-6.","metaTitle":"Siemens 5SL4350-7CC SENTRON MCB, 3P C 50A 10kA 400V","metaDescription":"Siemens SENTRON 5SL4350-7CC miniature circuit breaker, 3-pole, C-curve, 50 A, 10 kA breaking capacity at 400 V AC.
