## Summary description

The ABB S 201-B 20 is a high-quality 1-pole miniature circuit breaker designed for reliable electrical circuit protection. It features a rated current of 20A and operates at a voltage of 230/400V with a frequency of 50/60 Hz. This device is engineered for industrial and residential electrical installations to prevent overcurrent and short-circuit damage, ensuring safety and operational stability in your power distribution system.

## Long description

The ABB S 201-B 20 is a professional-grade 1-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. This device is designed to safeguard residential, commercial, and industrial power distribution systems by effectively managing overcurrent and short-circuit risks. With a rated current of 20A and compatibility with 230/400V systems, it ensures consistent operational stability and safety for connected electrical infrastructure.
Advantages
This circuit breaker utilizes a dual-tripping mechanism to ensure comprehensive protection. The delayed thermal tripping mechanism is specifically calibrated to handle overload conditions, while the electromechanical tripping mechanism provides rapid response during short-circuit events. Its current-limiting design helps minimize potential damage to downstream equipment. Furthermore, the compact construction allows for efficient space utilization within distribution boards, and the ability to mount bottom-fitting auxiliary contacts further optimizes installation space by up to 50 percent.
Suitable for
Residential electrical distribution boards
Commercial building power systems
Industrial machinery and control panels
Protection of lighting and general-purpose circuits
When it may not be suitable
This device is not intended for use in DC circuits unless specifically rated for such applications. It may also be unsuitable for high-inrush current applications where a different tripping characteristic, such as C or D, would be required to prevent nuisance tripping.
Key specifications
Rated current: 20A
Number of poles: 1
Tripping characteristic: B
Rated voltage: 230/400V AC
Frequency: 50/60 Hz
Weight: 0.125 kg
Compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077, CSA 22.2 No. 235
How to use
The circuit breaker is designed for mounting on a standard DIN rail within an electrical distribution enclosure. Installation should be performed by a qualified electrician in accordance with local electrical codes. Ensure that the supply voltage and load requirements match the specifications of the device before connection. The unit is operated via the front-facing toggle switch, which indicates the status of the circuit.
What to consider before purchase
Verify that the 20A rating is appropriate for your specific circuit load.
Ensure the B-characteristic is suitable for your intended application.
Check available space in your distribution board for installation.
Confirm compatibility with existing DIN rail systems.
Usage recommendations
Always ensure the power supply is disconnected before attempting installation or maintenance. Regularly inspect the device for signs of wear or damage to maintain optimal safety standards.
