Reliable Circuit Protection for Electrical Installations
Miniature circuit breakers protect electrical circuits by automatically interrupting current when an overload or short circuit occurs. The ABB S204M-D4 combines this protective function with a four-pole configuration, making it suitable for applications requiring coordinated protection across multiple conductors.
The D characteristic is intended for circuits where equipment can produce higher starting or inrush currents. This makes the S204M-D4 suitable for applications such as certain motors, transformers and other electrical loads with substantial short-duration current demand, while maintaining automatic protection against sustained overloads and short circuits.
Typical Applications
- Industrial electrical distribution boards.
- Motor and transformer circuits with higher inrush currents.
- Industrial control panels and machinery circuits.
- Building services and commercial electrical installations.
- Automation and control system protection.
- General low-voltage AC circuit protection.
