Technical Specifications / Parameters Parameter Specification Manufacturer Type Code GSH201 AC-D16/0.03 Brand / Series ABB System PRO M compact® (GSH201 Series) Device Type Residual Current Circuit Breaker (RCCB) / Residual Current Operated Circuit-Breaker without Integral Overcurrent Protection Number of Poles 1-Pole + Neutral (1P+N). It protects a single-phase circuit by monitoring both the Phase and Neutral conductors. Rated Current (In) 16 A (This is the maximum continuous current the device can carry. It does NOT provide overload protection). Rated Residual Operating Current (IΔn) 30 mA (High sensitivity, providing protection against direct contact / electric shock). Residual Current Type Type AC: Sensitive to sinusoidal alternating residual currents only. Rated Operational Voltage (Ue) 230 V AC (Single-phase) Rated Insulation Voltage (Ui) 500 V AC Tripping Characteristic Instantaneous (<0.1 seconds) for residual currents ≥ IΔn. Non-tripping Residual Current 0.5 x IΔn (15 mA) guaranteed. Short-Circuit Capacity Requires series protection by an upstream MCB (e.g., SH201-C16). Its own withstand rating is typically 4.5kA or 6kA (IEC 61008). Mechanical Life ≥ 20,000 operations Electrical Life ≥ 20,000 operations (at In) Test Button Yes. A built-in push-button ("T") to simulate a fault and verify proper functionality. Mounting DIN Rail Mounting (35 mm symmetrical rail, EN 60715) Module Width 36 mm (2 modules) Standards Compliance IEC/EN 61008-1, IEC/EN 61009-1 (for RCBOs, relevant for construction), CE, CCC, etc. Terminals Cage Clamp Terminal for both Phase and Neutral. Connectable Conductors Rigid/Flexible Copper: 1 - 25 mm² Ambient Temperature Range -25°C to +55°C (for calibration)
