At 6 A on a 4-pole 400 V system, this breaker protects a 3-phase load drawing roughly 4 kVA. The 4-pole configuration is standard for TN-S or TN-C-S systems where the neutral requires overcurrent protection. The D-curve holds through motor starting current. ## Panel integration Snap-on DIN rail mounting for standard 35 mm rail. The 4-pole width occupies 4 module spaces (roughly 72 mm). Verify the available DIN rail length in your enclosure before committing the BOM line.","metaTitle":"Siemens 5SL6406-8CC Miniature Circuit Breaker, 400V 6kA, 4-P","metaDescription":"Siemens 5SL6406-8CC miniature circuit breaker, 400V 6kA, 4-pole, D-curve, 6A.
