## Long description

The ABB S203-C20 is a high-performance 3-pole miniature circuit breaker engineered to provide reliable protection for electrical circuits in demanding environments. Designed for industrial and commercial power distribution, this device effectively safeguards systems against overloads and short circuits. It utilizes a dual-tripping mechanism, combining a delayed thermal element for overload protection and an electromechanical element for rapid short-circuit response, ensuring consistent safety and operational stability.
Advantages
This circuit breaker stands out due to its robust construction and high-quality engineering, which ensure long-term durability even in intensive electrical installations. Its current-limiting design minimizes the energy let-through during a fault, protecting downstream equipment from damage. The compact design allows for efficient use of space within distribution boards, and the ability to mount bottom-fitting auxiliary contacts further optimizes installation space by up to 50 percent. Compliance with international standards guarantees that this device meets rigorous safety and performance requirements for diverse global applications.
Suitable for
Industrial power distribution systems
Commercial building electrical installations
Protection of three-phase motors and equipment
General electrical circuit safety in professional settings
This device is not intended for use in circuits exceeding its rated voltage of 440V or current capacity of 20A. It is also not suitable for applications requiring specific tripping characteristics other than the C-curve, such as highly sensitive electronic equipment that may require different protection profiles.
Key specifications
Number of poles: 3
Rated current: 20A
Rated voltage: 440V AC
Tripping characteristic: C
Frequency: 50/60 Hz
Standards compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077, CSA 22.2 No. 235
The installation of the ABB S203-C20 should be performed by a qualified electrician in accordance with local electrical codes. The device is designed for DIN-rail mounting within a standard distribution enclosure. Ensure that all wire connections are tightened to the manufacturer's specified torque to prevent overheating and ensure a secure electrical contact. Once installed, the toggle switch can be used to manually disconnect or reconnect the circuit as needed.
What to consider before purchase
Verify that the 20A rated current matches your specific load requirements.
Ensure the 3-pole configuration is appropriate for your three-phase electrical system.
Check that the C-curve tripping characteristic is suitable for the intended application.
Confirm compatibility with your existing distribution board and DIN-rail setup.
For optimal performance and safety, regularly inspect the circuit breaker for signs of wear or damage and ensure that the electrical load does not consistently exceed the rated current capacity of the device.
