The 1 A rated current and D-curve (10–20x In magnetic trip) make this the right choice for a circuit feeding a small motor starter, a control transformer, or a bank of LED drivers where the startup surge exceeds what a B- or C-curve would tolerate without tripping. The 5 kA rating under UL 1077 and CSA C22.2 No. 235 covers North American installations where the available fault current is lower. Wire range accepts 0.75 to 35 mm² solid or stranded, and the screw terminals call for 2.5 to 3.5 N·m torque — that's a wide lugging range for a 1 A breaker, letting you land a fat feeder or a thin control wire without adapters. Combined terminals top and bottom mean you can feed from either end, and the sealable cover lets you lock settings after commissioning. Lifecycle stage is current — no phase-out or last-time-buy notice on this order code. If you're holding a BOM that specifies the 5SY7140-8CC (a 40 A D-curve 2P), this 1 A version shares the same 2-pole, D-curve, 5SY7CC design and the same physical footprint — 36 mm wide, 76 mm deep, same terminals — so it's a drop-in swap for the same frame size at a different current rating. The 5SY7201-8CC carries IEC 60947-2 and UL 1077 / CSA C22.2 No. 235 approvals — covering the main international and North American standards for supplementary protectors. Overvoltage category III means it's rated for fixed-installation distribution panels, not just downstream equipment. Siemens provides the standard declaration of conformity and CE marking for this SENTRON series; RoHS and REACH compliance documentation is available on request through the supply channel.","metaTitle":"Siemens 5SY7201-8CC SENTRON MCB, 1A D-curve 2P, 50kA IEC","metaDescription":"Siemens SENTRON 5SY7201-8CC miniature circuit breaker, 1A rated, D tripping characteristic, 2-pole, 400V AC, 50kA IEC 60947-2 breaking capacity, 5kA UL 1077.
