It sits in the Basic Devices product family, Group Code P310, Product Group 3819. The B curve (3–5× In) trips fast on moderate overloads — suited for resistive and general-purpose loads, not high-inrush motor circuits. The 1+N-pole form factor switches both line and neutral, fitting standard single-phase consumer units. ## Deployment context Snap-on DIN rail mounting for panel integration. The neutral pole is switched, so verify the neutral bus bar arrangement in your distribution board — this MCB opens the neutral on fault, which is typical for UK/EU single-phase final circuits.","metaTitle":"Siemens 5SL6503-6CC Miniature Circuit Breaker, 1+N-pole, B C","metaDescription":"Siemens 5SL6503-6CC miniature circuit breaker, 230V, 6kA, 1+N-pole, B curve, 3A.
