Frequently Asked Questions

What does the C-curve tripping characteristic mean?
The C-curve trips between 5× and 10× the rated current on magnetic short-circuit release, making the ABB S201-C32 suitable for resistive and low-inductive loads such as lighting and heating circuits.

Is the S201-C32 suitable for three-phase systems?
The S201-C32 is a single-pole (1P) device rated at 230/400V AC. It can protect individual phases in a three-phase system when used with the appropriate busbar accessories from the S200 series.

What DIN-rail width does this MCB require?
The ABB S201-C32 has a module width of 17.5 mm and mounts on standard 35 mm DIN-rail (EN 60715).
