## Summary description

The ABB S203-C20 is a high-quality 3-pole miniature circuit breaker designed for reliable electrical circuit protection. It features a rated current of 20 A and supports an input voltage of 440 V at 50/60 Hz. This robust device is engineered for industrial and residential electrical installations, ensuring safety by preventing overcurrent and short-circuit damage in power distribution systems.

## Long description

The ABB S203-C20 is a professional-grade 3-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits. Designed to handle a rated current of 20 A and an operating voltage of 440 V, this device serves as a critical component in power distribution systems. It utilizes advanced current-limiting technology to safeguard electrical installations against the risks of overcurrent and short-circuit damage, ensuring consistent performance in demanding environments.
Advantages
This circuit breaker features a dual-tripping mechanism that combines delayed thermal protection for managing overloads with an electromechanical system for immediate short-circuit response. Its robust construction ensures long-term reliability and safety in both residential and industrial settings. The design supports space-saving installations, including the option to mount bottom-fitting auxiliary contacts, which helps optimize panel space by up to 50 percent.
Suitable for
Industrial power distribution systems
Commercial building electrical panels
Residential electrical installations
Protection of electrical circuits against overcurrent and short circuits
When it may not be suitable
This device is not intended for use in circuits exceeding its rated current of 20 A or voltage specifications of 440 V. It should not be installed in environments that require specific tripping characteristics other than the C-curve, such as applications requiring highly sensitive Z or K characteristics for specialized electronic equipment.
Key specifications
Number of poles: 3
Rated current: 20 A
Rated voltage: 440 V AC
Tripping characteristic: C
Compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077, CSA 22.2 No. 235
How to use
The ABB S203-C20 should be installed by a qualified electrician onto a standard DIN rail within a distribution board or consumer unit. Ensure that the supply cables are securely connected to the terminals according to the specified torque requirements. Once installed, the device acts as an automatic switch that monitors the circuit; in the event of a fault, the toggle will move to the off position, allowing for manual reset once the underlying issue has been resolved.
What to consider before purchase
Verify that the 20 A current rating matches your circuit requirements
Ensure the 3-pole configuration is appropriate for your specific power supply
Check that the C-curve tripping characteristic is suitable for your connected loads
Confirm compatibility with existing DIN rail mounting systems
Usage recommendations
Always ensure that the electrical system is de-energized before attempting installation or maintenance. Regularly inspect the circuit breaker for signs of wear or damage and test the functionality periodically to ensure continued protection of your electrical infrastructure.
