Technical Parameters Parameter Category Specification Product Series System Pro M compact - GSE Series Device Type Miniature Circuit Breaker (MCB), 3-Pole, with Special Auxiliary Protection Standard Compliance IEC/EN 60898-1 Number of Poles 3 Poles (3P) for main circuit protection. Rated Current (In) & Characteristic C32 • C: Tripping Characteristic (Instantaneous trip range: 5 to 10 times In). Suitable for general purposes with moderate inrush currents. • 32: Rated Current = 32 A per pole. Circuit Type AC ONLY (as indicated by AC). Rated Operational Voltage (Ue) 400/690 V AC Handle Type L - Side-operated rotary lever handle. Provides clear ON/OFF indication and comfortable manual operation. Special Feature /0.03 - Integrated 0.03A (30mA) protection element. • Likely Configuration: This is not a standard RCBO (residual current) trip. It is most plausibly a separate, very low-current fuse or electronic protector embedded within the MCB housing. • Protected Circuit: This likely protects a separate pair of terminals (e.g., auxiliary contacts 13-14 or a dedicated control input) used for remote signaling, undervoltage release (MN) coil, or self-powered electronic logic within the breaker. Its purpose is to prevent damage to external control devices if a fault occurs in that circuit. Breaking Capacity (Icn) Typically 6 kA or 10 kA at 400V AC for the base GSE203 model. Higher capacity versions exist (e.g., H version: 15 kA). Energy Limiting Class 3 Electrical Life ≥ 20,000 cycles at rated current Mechanical Life ≥ 20,000 cycles Terminals Screw-clamp terminals for main conductors. Additional small terminals likely for the /0.03 protected circuit. Mounting Standard 35 mm DIN Rail (EN 60715) Width 54 mm (3 module width) Ambient Temperature -25°C to +55°C Protection Degree IP20
