Description

ABB Residual Current Breaker Overcurrent Protection (RCBO) ABB DS201L RCBO 1P+N | 4.5kA Breaking Capacity | A-Type C-Curve Protection

The ABB DS201L Residual Current Circuit Breaker with Overcurrent Protection is an advanced solution for modern electrical installations.

This combined device meets the highest safety standards (IEC/EN 61009-1) [cite] by simultaneously guarding against:

1. Overload and Short-Circuit Currents (MCB function).
2. Earth Fault Currents (RCD function).

Key Performance Specifications:

• Advanced Earth Fault Protection: The A-Type technology ensures detection of currents from standard AC loads and challenging direct pulsating DC currents often generated by modern electronics.
• Tripping Curve: The C-Characteristic curve is standardized for general applications, providing reliable protection for resistive and inductive loads.
• Breaking Capacity: Its conditional short-circuit breaking capacity (Icn) of 4500A ensures robust performance under fault conditions.
• Range: The module is available in various rated currents (In) from 6A up to 32A.

The DS201L is the ideal modular protection unit for installers requiring a highly compact, robust, and reliable 1P+N breaker solution.
