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
The ABB SACE Emax E3 3200A refers to a large-frame, low-voltage air circuit breaker (ACB) from ABB's flagship Emax series. The designation highlights two key identifiers: the E3 physical frame size and its 3200-Ampere rated operational current.
