Frequently Asked Questions

What does the C-curve trip characteristic mean for the S204-C1?

The C-curve means the breaker will trip instantaneously at 5–10 times the rated current (5–10 A). This is suitable for general loads with moderate inrush currents, such as resistive loads, lighting circuits, and control transformers.

Is the ABB S204-C1 suitable for 3-phase systems?

Yes. With 4 poles rated at 400 V AC, the S204-C1 is designed for use in 3-phase + neutral (TN-S) systems, providing simultaneous protection and isolation across all four conductors.

What DIN-rail width does the S204-C1 occupy?

The S204-C1 has a width of 88 mm, which corresponds to 4 module widths (4 × 18 mm) on a standard EN 60715 DIN rail — one module per pole.
