ABB S 201-B 6 Miniature Circuit Breaker

The ABB S 201-B 6 is a high-performance miniature circuit breaker engineered to provide robust protection for electrical circuits. As part of the System pro M compact S200 series, this device is designed to safeguard residential, commercial, and industrial installations against the risks of overcurrent and short circuits. By integrating both thermal and electromechanical tripping mechanisms, it ensures precise and reliable operation in various power distribution environments.

Advantages

This circuit breaker offers exceptional reliability through its dual-action protection system, which combines a delayed thermal mechanism for overload detection and an electromechanical mechanism for rapid short-circuit response. Its current-limiting design helps minimize potential damage to downstream equipment during fault conditions. The compact construction allows for efficient use of space within distribution boards, and the ability to mount auxiliary contacts at the bottom further optimizes installation density, saving up to 50% of space compared to standard configurations.

Suitable for

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

This device may not be suitable for applications requiring higher breaking capacities than 6 kA or for circuits exceeding the rated current of 6 A. It is specifically designed for AC systems and should not be used in DC environments unless explicitly rated for such use by the manufacturer.

Key specifications

• Rated current: 6 A
• Tripping characteristic: B
• Number of poles: 1P
• Breaking capacity: 6 kA
• Compliance: IEC/EN 60898-1, IEC/EN 60947-2, UL1077, CSA 22.2 No. 235

Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is designed for DIN-rail mounting within a standard distribution enclosure. Ensure that the supply voltage and load requirements are compatible with the breaker specifications before finalizing the connection.

What to consider before purchase

• Verify the required tripping characteristic for your specific load type
• Ensure the rated current matches the connected circuit demand
• Check available space in the distribution board for mounting
• Confirm compatibility with existing DIN-rail systems

For optimal performance and safety, ensure all terminal connections are tightened to the manufacturer's specified torque settings and inspect the device periodically for signs of thermal stress or mechanical wear.
