ABB DS201 Series Residual Current Circuit Breakers

Ideal for residential, commercial, and industrial distribution boards, the DS201 series ensures compliance with global standards while offering high mechanical durability (up to 20,000 operating cycles) and robust performance in harsh environments

• Triple Protection: Combines overload, short-circuit (up to 6 kA breaking capacity), and residual current (30–300 mA) protection

• Versatile Tripping Characteristics: C-type tripping curve for balanced response to moderate inrush currents

• Compact Design: 2-module width optimizes space in high-density panels

• Enhanced Safety: IP40 enclosure rating and fault-indicating blue toggle switch for quick diagnostics

• Transient Interference Immunity: APR models resist nuisance tripping from voltage spikes

• Broad Compatibility: Supports AC and A-type residual currents for sinusoidal or pulsating DC fault detection

• Easy Installation: DIN rail clip-on mounting and bidirectional terminals for 0.75–25 mm² cables
