Frequently Asked Questions

What does the C in SH203-C20 mean?
The C denotes the tripping curve. A C-curve MCB trips magnetically at 5–10× rated current, making it suitable for loads with moderate inrush currents such as motors, transformers, and fluorescent lighting.

What is the breaking capacity of the SH203-C20?
The SH203-C20 has a rated breaking capacity (Icu) of 6 kA at 400V AC, in accordance with IEC/EN 60898-1.

Is the SH203-C20 DIN rail mountable?
Yes, the ABB SH200 series MCBs are designed for standard 35mm DIN rail mounting, compatible with all common distribution board formats.

What voltage system is the SH203-C20 rated for?
The SH203-C20 is rated for 230/400V AC, suitable for use in standard single-phase and three-phase low-voltage networks.
