Why Choose the ABB S204M-C20 Miniature Circuit Breaker?

The ABB S204M-C20 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 provides dependable overcurrent protection while its modular construction allows straightforward integration into distribution boards and control panels.

With a 20 A rated current, four-pole configuration and AC supply capability, the S204M-C20 is suited to protecting multi-phase electrical circuits where a C-characteristic breaker is required. Its DIN-rail mounting enables convenient installation in modular low-voltage electrical assemblies.

Key Advantages

  • Compact miniature circuit breaker designed for electrical circuit protection.
  • 20 A rated current suitable for distribution and control circuits.
  • Four-pole configuration for protection and switching of multi-phase circuits.
  • C tripping characteristic suitable for circuits with moderate starting or inrush currents.
  • 10 kA rated breaking capacity for specified AC applications.
  • 15 kA ultimate short-circuit breaking capacity under specified AC conditions.
  • DIN-rail mounting for convenient installation in modular electrical assemblies.

Key Features

  • ABB System pro M compact S200M series.
  • 20 A rated current.
  • Four-pole configuration.
  • C tripping characteristic.
  • 10 kA rated breaking capacity under specified conditions.
  • 15 kA ultimate breaking capacity under specified AC conditions.
  • Thermal overload and electromagnetic short-circuit protection.
  • DIN-rail mounting for modular distribution equipment.
  • Suitable for residential, commercial and industrial electrical installations.

Reliable Circuit Protection for Electrical Installations

The ABB S204M-C20 protects electrical circuits from sustained overloads and short-circuit faults. Its thermal protection responds to prolonged excessive current, while electromagnetic protection provides rapid interruption during short-circuit conditions.

The C characteristic allows a moderate level of transient current before magnetic tripping, making this type of circuit breaker suitable for general-purpose circuits and loads with moderate starting currents. Combined with its four-pole construction and modular DIN-rail format, the S204M-C20 can be integrated into a wide range of electrical distribution and control systems.

Typical Applications

  • Residential electrical distribution boards.
  • Commercial electrical distribution systems.
  • Industrial control panels and electrical cabinets.
  • Lighting and general-purpose electrical circuits.
  • Machinery and equipment circuits with moderate inrush currents.
  • Control and auxiliary circuits requiring four-pole protection.
