## Summary description

The ABB S203-C50 is a 3-pole miniature circuit breaker designed for reliable electrical circuit protection. It features a rated current of 50 A and a rated voltage of 400 V, operating at a frequency of 50-60 Hz. With an IP20 protection rating and a durable grey finish, this device is suitable for industrial and residential electrical distribution systems, ensuring safety against overloads and short circuits.

## Long description

The ABB S203-C50 is a high-performance 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits against overloads and short circuits. As part of the System pro M compact S200 series, this device utilizes both a delayed thermal tripping mechanism for overload scenarios and an electromechanical mechanism for rapid short-circuit response, ensuring consistent safety and reliability in various electrical installations.
Advantages
This circuit breaker offers exceptional reliability through its current-limiting design, which effectively minimizes the energy released during a fault. Its compact construction allows for efficient space utilization within distribution boards, and the ability to mount auxiliary contacts at the bottom further optimizes panel space. The device is built to meet rigorous international standards, ensuring compatibility and safety across residential, commercial, and industrial environments.
Suitable for
Industrial electrical distribution systems
Commercial building power management
Residential electrical panels
Protection of circuits with moderate inrush currents
This device may not be suitable for applications requiring specific tripping characteristics other than the C-curve, such as highly sensitive electronic equipment that might require a different protection profile. It is also not intended for use in environments exceeding its rated voltage or current capacity.
Key specifications
Number of poles: 3
Rated current: 50 A
Rated voltage: 400 V AC
Frequency: 50-60 Hz
Tripping characteristic: C
Protection rating: IP20
Compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077
How to use
The ABB S203-C50 is designed for DIN-rail mounting within a standard electrical distribution board. Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is snapped onto the rail, and the supply and load cables are connected to the respective terminals. Ensure all connections are tightened to the manufacturer's specified torque to prevent overheating.
What to consider before purchase
Verify that the 50A rating matches your circuit load requirements.
Ensure the 3-pole configuration is compatible with your three-phase power supply.
Check that the C-curve tripping characteristic is appropriate for your specific connected loads.
Confirm that the installation environment meets the IP20 protection rating requirements.
Usage recommendations
Regular inspection of the circuit breaker and terminal connections is recommended to ensure long-term operational safety. Do not attempt to modify the internal tripping mechanisms, as this will void the warranty and compromise the safety of the electrical system.
