Parameters: Model Number: ABB E3N2500 R2500 PR121/P-LSIG WHR 3P Rated Voltage: 400 V AC (Three-phase) Rated Current: 2500 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, ensuring that the system is protected from prolonged overcurrents. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, providing protection against short-circuit faults while preventing nuisance tripping. Instantaneous Protection (I): Instantaneous tripping for severe short-circuit conditions, ensuring the system is protected from high fault currents. Ground Fault Protection (G): Ground fault protection (LSIG) detects leakage currents or faults and isolates the faulty section, improving system safety. Thermal Overload Protection: Protects against overheating of motors by monitoring temperature and adjusting protection settings as needed to ensure the equipment operates within safe thermal limits. Wide Heat Range (WHR): Ensures adaptability to different environmental temperatures, allowing for use in diverse operational conditions. Breaking Capacity (Icu): 50 kA at 400 V, suitable for handling high fault currents and ensuring rapid and safe disconnection during fault conditions. Mounting Type: DIN rail or panel mount for easy installation in electrical panels, motor control centers (MCCs), and distribution boards. Degree of Protection: IP20 (suitable for indoor environments; optional external protection kits available for harsher environments). Weight: Approx. 20–25 kg (depending on configuration). Dimensions (H x W x D): Approx. 500 x 300 x 200 mm (subject to configuration). Control Voltage: 24 V DC (external supply for control and communication functions). Modbus RTU Communication (Optional): For integration with PLC or SCADA systems, enabling remote monitoring, fault detection, and diagnostics. Auxiliary Contacts (Optional): Available for use with control systems to signal faults or provide status information to external systems.
