Product information

Description

The ABB S203-B25 is a professional-grade 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed as part of the System pro M compact S200 series, this device ensures high reliability in both residential and industrial electrical installations. It utilizes a dual-tripping mechanism, combining a thermal system for overload protection with an electromechanical system for rapid short-circuit response, ensuring comprehensive safety for your electrical infrastructure.

Advantages

This circuit breaker offers superior current-limiting capabilities, which significantly reduces the energy let-through during a fault, thereby protecting downstream components from damage. Its compact design allows for efficient use of space within distribution boards, and the ability to mount auxiliary contacts at the bottom further optimizes installation space by up to 50 percent. The device is built to meet rigorous international standards, ensuring consistent performance and long-term durability in demanding environments.

Suitable for

  • Residential electrical distribution boards
  • Commercial building power systems
  • Industrial machinery and control panels
  • Protection of lighting and heating circuits

When it may not be suitable

This device is specifically designed for applications requiring a B-curve tripping characteristic. It may not be suitable for circuits with high inrush currents, such as those powering large motors or transformers, where a C or D-curve breaker would be more appropriate to prevent nuisance tripping.

Key specifications

  • Number of poles: 3
  • Rated current: 25A
  • Tripping characteristic: B-curve
  • Rated voltage: 440V AC
  • Frequency: 50/60 Hz
  • Compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077, CSA 22.2 No. 235

How to use

The ABB S203-B25 should be installed by a qualified electrician within a standard DIN-rail distribution enclosure. Ensure that the supply voltage and load requirements match the specifications of the device. The breaker is mounted by snapping it onto the DIN rail and connecting the input and output cables to the respective terminals, ensuring all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

  • Verify that the 25A rating is appropriate for your specific circuit load.
  • Confirm that the B-curve characteristic matches the requirements of your connected equipment.
  • Ensure the 3-pole configuration is compatible with your electrical system phase arrangement.
  • Check available space in your distribution board for installation.

Usage recommendations

Always ensure the power supply is disconnected before attempting any installation or maintenance work on the circuit breaker. Regularly inspect the device for signs of physical damage or overheating to maintain optimal safety standards.
