Parameters: Model Number: ABB SACE PR121/P-LI Rated Voltage: 400 V AC (Three-phase) Rated Current: 320 A to 800 A (adjustable) Frequency: 50/60 Hz Breaking Capacity (Icu): 50 kA at 400 V Protection Type: Long-Time Protection (L): Adjustable from 0.7 to 1.0 times rated current. Protects the system from prolonged overcurrent conditions, preventing motor or equipment damage. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with an adjustable time delay, to prevent nuisance trips while providing protection against short circuits. Instantaneous Protection (I): Provides fast disconnection for severe short-circuit conditions to protect against high fault currents. Thermal Overload Protection: Continuously monitors the motor or equipment temperature to prevent overheating from prolonged overload conditions. Short-Circuit Protection: Safeguards against the damaging effects of short circuits, ensuring fast and reliable fault isolation. Control Voltage: 24 V DC (external supply) Mounting Type: DIN rail mount or panel mount Degree of Protection: IP20 (suitable for indoor use; optional kits for enhanced protection in harsh environments) Weight: Approx. 12 kg (depends on configuration) Dimensions (H x W x D): Approx. 450 x 250 x 200 mm (subject to configuration) Modbus RTU Communication (Optional): For integration with PLC or SCADA systems, allowing for remote monitoring, diagnostics, and control. Auxiliary Contacts (Optional): Available for use in larger control systems to provide feedback or fault signals to operators.
