Frequently Asked Questions

What is the difference between the S201M-C20 and the standard S201 series?
The S200M series offers an enhanced breaking capacity of 10kA at 400V AC compared to the 6kA standard of the base S200 series, making it suitable for installations with higher prospective fault currents.

Is the ABB S201M-C20 compatible with ABB auxiliary contacts and motor operators?
Yes. The S200M series is designed to accept ABB S200 range accessories including auxiliary contacts, alarm contacts, and remote motor operators, ensuring system flexibility in automation and energy management panels.

What does the C-curve trip characteristic mean?
A C-curve MCB trips magnetically at 5–10 times the rated current, making it ideal for protecting circuits with moderate inrush loads such as lighting, small motors, and general-purpose socket outlets.
