This is the part that sits on the DIN rail in a distribution board, protecting a single-phase final subcircuit — lighting or general-purpose socket outlets — where the B-curve's magnetic trip threshold (3 to 5 times In) clears short-circuits fast enough to avoid nuisance trips from moderate inrush, yet still coordinates with upstream SENTRON selective main breakers. RoHS-compliant since 01 June 2013, but the REACH candidate list declares lead (CAS-No. 7439-92-1) above 0.1% w/w — standard for alloyed terminals in this class.","metaTitle":"Siemens 5SL4120-6CC MCB, 1-pole B 20 A, 10 kA","metaDescription":"Active Siemens 5SL4120-6CC miniature circuit breaker, 230/400 V, 10 kA, 1-pole, B-curve, 20 A.
