Rated breaking capacity is 10 kA per EN 60898 and 15 kA per IEC 60947-2 at 400 V AC — that covers most commercial and light industrial panelboards where the available fault current stays under 10 kA. The 15 kA IEC rating gives headroom for industrial MCCs with higher SCCR requirements. ## What the C-curve and ratings mean for your circuit For a 1 A MCB like this, that is 5–10 A instantaneous trip — designed for moderate inrush loads such as lighting banks, contactor coils, and small control transformers. Not for motor starting (use D-curve) or purely resistive loads (B-curve). The 2-pole configuration switches both phase conductors, with no neutral switching. Sealable design (yes) allows the handle to be locked in the OFF position with a padlock — a hard requirement for lockout/tagout procedures. If it's not locked, it's not safe.","metaTitle":"Siemens 5SJ4201-7HG41 2-Pole MCB, C-Curve, 10 kA","metaDescription":"Siemens 5SJ4201-7HG41 SENTRON 2-pole MCB, C-curve, 10 kA per EN 60898, 15 kA per IEC 60947-2.
