ABB DSH201 B10 Residual Current Circuit Breaker with Overcurrent Protection, 2P, 10A, 30mA, AC, 6kA

The ABB DSH201 B10 is a professional-grade residual current circuit breaker with overcurrent protection (RCBO), engineered to provide comprehensive safety for electrical installations. This 2-pole device combines the functions of a miniature circuit breaker and a residual current device in a single compact unit, ensuring efficient protection against short circuits, overloads, and earth leakage currents in both residential and commercial environments.

Advantages

This RCBO offers a high level of operational reliability by integrating two critical safety functions into one space-saving module. Its robust design ensures consistent performance under standard electrical loads, effectively minimizing the risk of fire and electrical shock. The device is built to high manufacturing standards, providing long-term durability and stable protection for sensitive electronic equipment and household appliances.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of individual final circuits
• Preventing electrical hazards in damp or high-risk areas

This device is not suitable for industrial applications requiring high-voltage protection or specialized DC-sensitive circuits, as it is designed specifically for AC-type leakage detection. It should not be used in environments where the electrical load consistently exceeds the 10A rated current capacity.

Key specifications

• Number of poles: 2
• Rated current: 10A
• Sensitivity: 30mA
• Breaking capacity: 6kA
• Tripping characteristic: B
• Type: AC

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is mounted onto a standard DIN rail within a distribution board. Ensure that the supply voltage matches the device specifications before connection. Once installed, the integrated test button should be pressed periodically to verify the mechanical functionality of the leakage protection mechanism.

What to consider before purchase

• Verify that the 10A rated current is sufficient for your specific circuit load
• Ensure the 30mA sensitivity meets local safety requirements for your installation
• Confirm compatibility with existing DIN rail distribution systems
• Check that the AC type is appropriate for the equipment connected to the circuit

For optimal safety, perform a manual test of the device using the integrated test button at least every six months to ensure the tripping mechanism remains responsive.
