Technical Specifications Parameter Category Specification Product Series System Pro M compact - GSE Series Device Type Miniature Circuit Breaker (MCB), 3-Pole Standard Compliance IEC/EN 60898-1 (Primary standard for household and similar installations). May also comply with parts of IEC/EN 60947-2 for industrial applications. Number of Poles 3 Poles (3P). All three poles are identically protected. Rated Current (In) This is NOT defined by the "203" code alone. The 203 indicates a 3-pole frame. The rated current must be specified separately as a suffix. Common ratings for this frame: 1A, 2A, 4A, 6A, 10A, 13A, 16A, 20A, 25A, 32A, 40A. A complete model would be, for example: GSE203 C32 AC (3-Pole, C-curve, 32A). Tripping Characteristic Not specified in "GSE203 AC". Must be selected from: • B Characteristic: (3 to 5 x In) • C Characteristic: (5 to 10 x In) - Most common for general three-phase loads. • D Characteristic: (10 to 20 x In) - For loads with very high inrush currents. Circuit Type AC ONLY (as indicated by the AC suffix). Not suitable for DC circuits. Rated Operational Voltage (Ue) 400/690 V AC (Phase-to-Phase) Rated Insulation Voltage (Ui) 500 V AC Rated Impulse Withstand Voltage (Uimp) 6 kV (For overvoltage category III) Breaking Capacity (Icn) Depends on the specific version. Common ratings for the GSE203 base model: • Standard: 6 kA or 10 kA at 400V AC • High Performance (H version): 15 kA Energy Limiting Class 3 (High) Electrical Life ≥ 20,000 cycles at rated current Mechanical Life ≥ 20,000 cycles Handle Type Standard toggle (rocker) handle with clear ON/OFF indication. Terminals • Screw-clamp terminals suitable for rigid and flexible conductors. • Connection Capacity: Up to 35 mm² (depending on wire type). Mounting Standard 35 mm DIN Rail (EN 60715) Width 54 mm (3 module width = 3 x 18mm) Dimensions (W x H x D) 54 mm x 89 mm x 69 mm Ambient Temperature -25°C to +55°C (Reference calibration at 30°C) Protection Degree IP20 (When mounted in an enclosure) Certifications CE, CCC, and other international approvals.
