The D curve means it's built for loads with a high inrush, think small transformers or motor starters, where the magnetic trip needs to ride out the starting surge. It's a panel-mount DIN-rail unit, standard 1-module width, so it slots straight into a distribution board alongside other 5SY4 breakers.","metaTitle":"5SY4114-8CV MCB, 15 kA Icu, 1P D0.3, Current Production","metaDescription":"Siemens 5SY4114-8CV MCB, 15 kA Icu at 230/400 V, 1-pole D0.3 curve.
