Why Choose the ABB S204M-C4 Miniature Circuit Breaker?
The ABB S204M-C4 is a compact and reliable miniature circuit breaker (MCB) designed to protect electrical circuits against overloads and short circuits in residential, commercial and industrial installations. As part of the established ABB System pro M compact S200M series, it combines thermal and electromagnetic protection with a robust DIN-rail-mounted design.
This four-pole circuit breaker features a C tripping characteristic, making it suitable for circuits supplying loads with moderate inrush currents. The S200M range uses a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit protection, providing dependable circuit protection in a wide range of electrical distribution applications.
With a 4 A rated current, four-pole configuration and AC supply capability, the S204M-C4 is well suited to protecting multi-phase electrical circuits where compact modular protection and reliable fault interruption are required. Its DIN-rail mounting enables straightforward installation in distribution boards and control panels.

Reliable Circuit Protection for Electrical Installations
The ABB S204M-C4 protects electrical circuits from two principal fault conditions. Its delayed thermal tripping mechanism responds to sustained overloads, while the electromechanical tripping mechanism provides rapid protection against short circuits. This combination helps protect wiring and connected equipment from excessive current.
The C characteristic is designed for applications where connected loads can produce moderate transient currents during energisation. Combined with its four-pole construction and modular DIN-rail format, the S204M-C4 can be integrated into distribution boards, control panels and other low-voltage electrical assemblies.
Typical Applications
- Residential electrical distribution boards.
- Commercial power distribution systems.
- Industrial control panels and electrical cabinets.
- Low-current machine and equipment circuits.
- Lighting and general-purpose electrical circuits.
- Control and auxiliary circuits requiring four-pole protection.
