The D-curve means it tolerates high inrush currents — typically used for motor, transformer, or lighting loads where the start-up surge would nuisance-trip a B or C curve. It snaps onto a standard DIN rail in a distribution board or sub-panel. ## What the ratings mean for fit The 6 kA breaking capacity at 400 V is the maximum fault current the breaker can safely interrupt. For most commercial and light industrial distribution boards fed from a transformer of typical impedance, 6 kA is sufficient — but verify the prospective short-circuit current (PSCC) at the installation point. The D-curve (10-20× In magnetic trip) is the key selection parameter: use it where loads have a high starting surge, such as small motors, welding equipment, or discharge lighting. A C-curve would trip on the same inrush. ## Compliance and documentation RoHS compliance effective June 2013 covers the current production batch. REACH Article 33 data is available on request for the candidate substance list. Export control is AL: N / ECCN: N, meaning no special licensing for cross-border shipment to most destinations. Group Code P310 and Product Group 3821 are Siemens internal classification codes used for BOM system matching.","metaTitle":"Siemens 5SL6220-8CC Miniature Circuit Breaker, 400V 6kA, 2-p","metaDescription":"Siemens 5SL6220-8CC miniature circuit breaker, 400V 6kA, 2-pole, D-curve, 20A.
