Parameter Category Specification Series / Frame ABB SACE Emax, E3 Frame Rated Operational Current (In) 3200 A (Continuous current at 40°C ambient). This corresponds to the E3.4 specific model within the E3 frame. Rated Operational Voltage (Ue) 690 V AC Rated Insulation Voltage (Ui) 1000 V AC Breaking Capacity (Icu) - Options Must be specified. Common options for E3 frame: • H (High): 50 kA at 400V AC • N (Normal): 65 kA at 400V AC • S (Super): 100 kA at 400V AC Poles Typically 3-Pole or 4-Pole. Trip Unit Options (Must be selected) • Electronic: - PR121/P: For Tmax XT style logic on Emax (basic). - PR122/P: Most common advanced unit (LSI protection, measurement, communication). - PR123/P: For E4/E6 frames or special apps. • Thermal-Magnetic: Fixed protection (e.g., TMD, MIC logic). Mounting Style (Must be selected) • Fixed (F): Permanently wired. • Draw-out (W): Highly recommended for ease of maintenance and testing. Operating Mechanism Spring-operated stored energy. Manual or electrical charging. Standard Accessories (Typical) • Electric charging motor (M) • Shunt trip (MX) for remote opening • Auxiliary contacts (OF/SD) for status • Undervoltage release (MN) (These are selected via codes like FHR NST) Communication Available with electronic trip units (PR122/P, PR123/P) via optional modules (Modbus, Profibus, Ethernet). Mechanical Life ≥ 30,000 operations Electrical Life ≥ 10,000 operations at full rated current Short-Time Withstand Current (Icw) Matches or exceeds the Icu rating (e.g., 65 kA for 1 second). Dimensions (Approx. for 3P Fixed) Width: ~ 350-400 mm Height: ~ 550-600 mm Depth: ~ 400-450 mm Weight (Approx. for 3P Fixed) ~ 180 - 220 kg
