Description

ABB Residual Current Breaker Overcurrent (RCBO) DS201M 10000 A y type, K characteristic – Excellent Direct Pulsating Current Protection for Traction.

The ABB DS201 RCBO family—including the DS201, high-capacity DS201M, and specialized DS201T—provides the definitive all-in-one solution for circuit safety against overload, short-circuit, and dangerous earth fault currents in single-phase systems.

This comprehensive range is compliant with IEC/EN 61009-1 and features two breaking capacities: 6000A (Icn=6kA) for standard models, and a robust 10000A (Icn=10kA) for the DS201M, ensuring suitability for a wide array of installations.

The series guarantees superior residual current detection across three types:

• AC for standard sinusoidal earth faults;
• A, which is critical for modern loads as it detects both alternating and direct pulsating earth fault currents; and the advanced APR Type.
• The APR model is specifically engineered as an Anti-Nuisance device, providing enhanced resistance to unwanted tripping from transient surges, thereby maximizing service continuity without compromising safety.

Available in versatile B, C, and K tripping characteristics, these 1+N and 1P+N devices accommodate diverse load types, from resistive and lighting circuits (B-curve) to high-inrush motor and industrial equipment (C and K curves).

The DS201T is purpose-built for harsh railway, rolling stock, and traction environments. All 30 mA models offer essential additional protection against direct human contact, making them a safe choice globally.
