It snaps onto DIN rail inside a distribution board or control panel, protecting a single-phase branch circuit against overload and short-circuit. ## What the ratings mean for fit The C-curve (trips at 5–10× In) suits moderate inrush loads like small motors, transformers, or lighting banks — common in commercial and light industrial panels. The 6 kA breaking capacity at 400 V means it can safely interrupt a fault current up to that level without welding contacts or cascading upstream; verify the prospective short-circuit current at the installation point stays under that figure. The 3 A rating protects a branch drawing up to 3 A continuous; oversizing defeats the coordination.","metaTitle":"Siemens 5SL6103-7YA MCB 1-pole C 3A 6kA","metaDescription":"Siemens 5SL6103-7YA miniature circuit breaker, 230/400 V, 6 kA, 1-pole, C-curve, 3 A.
