Product Description

The ABB GS201 series is a line of 1P+N electronic residual current circuit breakers (RCBOs) designed for terminal distribution protection. Part of ABB’s global S200 series, these compact devices integrate earth fault protection with overload and short-circuit protection, ensuring electrical safety in residential, commercial, and industrial applications. Key innovations include dual-mode modularity (2-module width) and bidirectional terminals for simplified installation.

Standard Features

They support A-type residual current detection (sensitive to pulsating DC faults) and feature overvoltage protection (280V cutoff). Certified to IEC 61009 and GB 16917 standards, the GS201 series enhances system reliability with visual contact-position indicators (red/green) and compatibility with S200 accessories.

  • Rated Current: 6–63A (adjustable in steps, e.g., 10A, 16A, 40A)

  • Rated Residual Current: 10mA, 30mA, or 100mA (selectable models)

  • Breaking Capacity: 6 kA (IEC/EN standards)

  • Rated Voltage: 230V AC (1P+N configuration)

  • Tripping Characteristics: B (3–5In), C (5–10In), or D (10–20In)

  • Operating Temperature: –25°C to +55°C (storage: –40°C to +70°C)

  • Mechanical Life: 20,000 cycles
