Parameters:
Model Number: ABB SACE Emax E2 2000A PR121/P 3P
Rated Voltage: 400 V AC (Three-phase)
Rated Current: 2000 A (adjustable settings)
Frequency: 50/60 Hz
Protection Type:
Long-Time Protection (L): Adjustable from 0.7 to 1.0 times rated current for overload protection, helping prevent damage from prolonged overcurrents.
Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, to protect against short-circuit conditions without unnecessary tripping.
Instantaneous Protection (I): Provides instantaneous disconnection for severe short-circuit conditions, ensuring fast response to dangerous faults.
Ground Fault Protection (G): Ground fault protection (PR) detects leakage currents or faults in the system and isolates the faulty section to ensure safety.
Thermal Overload Protection: Monitors the system’s temperature to protect motors and transformers from overheating.
