Siemens 5SL series miniature circuit breaker, 400 V 6 kA, 4-pole C-curve, 1.6 A, Italy version.
The Siemens 5SL6415-7BB is a miniature circuit breaker (MCB) rated for 400 V with a 6 kA breaking capacity, 4-pole configuration, C-curve trip characteristic, and 1.6 A rated current. This is the Italy-market version of the 5SL series.
At 1.6 A per pole, this is a low-current branch protector, not a main feeder.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ to get a firm price and lead time.
The C-curve trips magnetically between 5× and 10× rated current (8 A to 16 A), so it handles moderate inrush from small motors or transformers without nuisance tripping. At 1.6 A, it's sized for low-current branch circuits — think control transformers, indicator lighting, or small relay panels.
