Why Choose the ABB S203MT-B16 Miniature Circuit Breaker?

The ABB S203MT-B16 is a high-performance three-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical systems. Part of ABB's traction-focused circuit protection range, it is suited to industrial, transportation and railway applications requiring dependable protection of electrical circuits.

The S203MT-B16 combines thermal-magnetic protection with a Type B tripping characteristic. Type B protection is suited to circuits with relatively low inrush currents, providing sensitive magnetic operation for appropriate resistive and general-purpose electrical loads while maintaining effective overload and short-circuit protection.

With a rated current of 16 A, three protected poles and a rated short-circuit breaking capacity of 10 kA, the S203MT-B16 provides robust protection for electrical circuits. Its modular construction supports convenient integration into industrial control panels, auxiliary systems and railway or traction equipment.

Key Advantages

  • 16 A rated current for dependable electrical circuit protection.
  • Three-pole configuration provides protection across three conductors.
  • Type B tripping characteristic suited to circuits with relatively low inrush currents.
  • 10 kA short-circuit breaking capacity for dependable fault protection.
  • Thermal-magnetic operation provides overload and short-circuit protection.
  • Designed for demanding industrial, DC and traction-related applications.

Key Features

  • ABB S203MT series circuit breaker.
  • 16 A rated current.
  • Three-pole miniature circuit breaker.
  • Type B thermal-magnetic tripping characteristic.
  • 10 kA short-circuit breaking capacity.
  • Designed for reliable overload and short-circuit protection.
  • Suitable for appropriate general-purpose circuits with relatively low inrush currents.
  • Compact modular construction for control and distribution assemblies.

Reliable Protection for Electrical Circuits

Miniature circuit breakers such as the ABB S203MT-B16 protect electrical circuits, conductors and connected equipment against overload and short-circuit conditions. The thermal-magnetic operating principle disconnects the protected circuit when defined overcurrent conditions occur, helping reduce the risk of damage to wiring and electrical equipment.

The combination of a 16 A current rating, Type B characteristic and 10 kA short-circuit breaking capacity makes the S203MT-B16 suitable for circuits where sensitive and dependable protection is required. Its three-pole configuration also makes it well suited to multi-conductor circuits within industrial, railway and traction-related installations.

Typical Applications

  • Railway and rolling-stock electrical systems.
  • Traction and transportation equipment.
  • Industrial control and auxiliary circuits.
  • Electrical distribution and protection panels.
  • General-purpose circuits with relatively low inrush currents.
  • Automation and control equipment.
