Parameters: Model Number: ABB E1N1000 R400/800/1000 3/4P Rated Voltage: AC 690 V (three-phase system) Rated Current: 400A, 800A, 1000A (adjustable depending on configuration) Frequency: 50/60 Hz Number of Poles: 3P (three-pole) or 4P (four-pole) Protection Type: Long-Time Protection (L): Adjustable from 0.7 to 1.0 times rated current, offering overload protection for sustained overcurrent conditions. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, providing protection against short-circuit faults while allowing for motor startup. Instantaneous Protection (I): Provides instantaneous disconnection in case of severe short-circuit conditions, ensuring the system is protected from high fault currents. Ground Fault Protection (G): Ground fault protection (LSI) detects leakage currents and isolates the faulty section, improving safety by preventing electrical hazards. Thermal Overload Protection: Monitors the temperature of the system and prevents overheating due to prolonged overload conditions. Breaking Capacity (Icu): 50 kA at 400V, ensuring safe interruption of high fault currents without damaging the system. Mounting Type: DIN rail mountable or panel mountable, making it easy to install in motor control centers (MCCs), distribution boards, and electrical control systems. Protection Class: IP20 (for indoor use; external protection kits available for more demanding environments). Weight: Approx. 10–20 kg, depending on the rated current and configuration. Dimensions (H x W x D): Approx. 300 x 200 x 180 mm (varies with rated current configuration). Control Voltage: Typically 24 V DC or 48 V DC for remote control and communication features. Communication Protocols: Can be equipped with Modbus RTU, Profibus, and Ethernet communication modules for remote monitoring, diagnostics, and integration into PLC or SCADA systems. Auxiliary Contacts (Optional): Available for signaling faults, system status updates, and integration into control systems.
