Frequently asked questions

What is the 5SL6615-7BB used for?

It is a miniature circuit breaker for 400 V three-phase circuits with a 6 kA breaking capacity, 3+N-pole, C-curve, rated 1.6 A. It protects wiring and loads against overload and short circuit in distribution boards.

Where can I buy the 5SL6615-7BB?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What does the C-curve on the 5SL6615-7BB mean?

The C-curve trips magnetically between 5x and 10x the rated current (1.6 A), so it handles moderate inrush from small motors or transformers without nuisance tripping, while still protecting the cable.
