Parameters: Model Number: ABB E3S 2000 PR121/P-LSIG Rated Voltage: 400 V AC (Three-phase) Rated Current: 320 A to 630 A (adjustable) Frequency: 50/60 Hz Protection Type: Long-Time Protection (L): Adjustable from 0.7 to 1.0 times rated current. Protects against prolonged overcurrents. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with time delay to prevent nuisance trips while offering protection against short circuits. Instantaneous Protection (I): Provides fast disconnection for severe short-circuit conditions to protect sensitive electrical equipment. Ground Fault Protection (G): Detects and isolates ground faults (leakage currents), helping to prevent electrical hazards and ensuring safety. Thermal Overload Protection: Monitors temperature and prevents motor or system overheating, preventing thermal damage. Breaking Capacity (Icu): 50 kA at 400 V Control Voltage: 24 V DC (external supply) Mounting Type: DIN rail mount or panel mount Degree of Protection: IP20 (for indoor use; optional protection kits for harsher environments) Weight: Approx. 7 kg (depending on configuration) Dimensions (H x W x D): Approx. 300 x 180 x 130 mm (varies depending on configuration) Modbus RTU Communication (Optional): For integration with PLC or SCADA systems, enabling remote monitoring, diagnostics, and fault detection. Auxiliary Contacts (Optional): Available for integrating with external control systems for monitoring or signaling.
