Technical Specifications / Parameters Parameter Specification Manufacturer Type Code GSH204 AC-S-C50/0.3 Brand / Series ABB System PRO M compact® (GSH200 Series - Selective RCBO) Device Type Selective (Time-Delayed) Residual Current Circuit Breaker with Overcurrent Protection (S-Type RCBO) Number of Poles 4-Pole (4P) Rated Current (In) 50 A Tripping Characteristic (Overcurrent) C Curve (Instantaneous magnetic tripping range: 5In to 10In, i.e., 250A to 500A). Rated Residual Operating Current (IΔn) 300 mA (0.3A) Residual Current Type Type AC: Sensitive to sinusoidal alternating residual currents only. Selective Trip Delay Yes. Contains a short, fixed time delay (typically compliant with Type S or Selective per IEC 61008/9, e.g., 40ms) on the residual current trip. This ensures discrimination with downstream devices. Rated Operational Voltage (Ue) 400 V AC (3P+N~) Rated Breaking Capacity (Icn) 6 kA (IEC/EN 61009-1) Mechanical Life ≥ 20,000 operations Test Button Yes. Mounting DIN Rail Mounting (35 mm symmetrical rail, EN 60715) Module Width 72 mm (4 modules) Standards Compliance IEC/EN 61009-1 (RCBO), with Selective (S-type) requirements. Terminals Cage Clamp Terminal. Connectable Conductors Rigid/Flexible Copper: 10 - 35 mm² (suitable for 50A).
