Parameters: Model Number: ABB E3N3200 R3200 PR121/P-LSI FHR 3P Rated Voltage: 400 V AC (Three-phase) Rated Current: 3200 A (adjustable) Frequency: 50/60 Hz Protection Type: Long-Time Protection (L): Adjustable from 0.7 to 1.0 times rated current for overload protection, which prevents equipment from damage due to prolonged overcurrent conditions. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, for short-circuit protection, providing immediate protection in the event of faults while allowing for motor startup. Instantaneous Protection (I): Provides instantaneous disconnection in the case of severe short-circuit conditions, protecting sensitive equipment from high fault currents. Ground Fault Protection (G): Ground fault protection (LSI) detects leakage currents or faults in the system and isolates the faulty section to prevent further damage or safety hazards. Thermal Overload Protection: Monitors the temperature of the system to prevent overheating, which could cause damage to motors or other components. Flexible High Resistance (FHR): Provides enhanced protection for motor-driven systems, allowing for adjustment to varying inrush currents and fluctuating load conditions that are common in motor-driven applications. Breaking Capacity (Icu): 70 kA at 400 V, ensuring safe interruption of high fault currents without causing damage to the system. Mounting Type: DIN rail or panel mount, making it easy to integrate into motor control centers (MCCs), distribution panels, and electrical control systems. Degree of Protection: IP20 (suitable for indoor environments; external kits available for harsher environments). Weight: Approx. 50–60 kg (depending on configuration). Dimensions (H x W x D): Approx. 650 x 500 x 250 mm (subject to configuration). Control Voltage: 24 V DC (external supply required for control and communication features). Communication Protocols: Modbus RTU, Profibus, and Ethernet for remote monitoring, diagnostics, and integration with PLC or SCADA systems. Auxiliary Contacts (Optional): Available for integration into control systems to signal faults and provide system status updates.
