Frequently Asked Questions

What does the C-curve trip characteristic mean?
The C-curve trips at 5–10× rated current for magnetic (instantaneous) operation, making the ABB S201-C16 suitable for loads with moderate inrush currents such as lighting, heating, and small motors.

Is the S201-C16 compatible with ABB residual current devices?
Yes. The S200 series is designed for use with ABB F200 and DS200 series RCCBs and RCBOs for combined protection.

What DIN rail width does this MCB require?
The S201-C16 occupies 17.5 mm (1 module) on a standard 35 mm DIN rail.
