Parameters:
Model Number: ABB E3S2000 R2000 PR121/P-LSI WHR 3P
Rated Voltage: 400 V AC (Three-phase)
Rated Current: 2000 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 helps prevent damage due to prolonged overcurrents.
Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, to provide short-circuit protection without unnecessarily tripping the system.
Instantaneous Protection (I): Provides instantaneous disconnection in the event of a severe short-circuit, 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 for safety.
Thermal Overload Protection: Continuously monitors the system's temperature, protecting the motor from overheating during overload conditions.
Wide Motor Protection (WHR): Provides enhanced protection for motors, helping to handle high inrush currents and load fluctuations that are typical in motor-driven systems.
Breaking Capacity (Icu): 65 kA at 400 V, ensuring safe interruption of high fault currents without damage to the system.
Mounting Type: DIN rail or panel mount, making it easy to install in motor control centers (MCCs), distribution boards, and electrical control systems.
Degree of Protection: IP20 (suitable for indoor environments; external protection kits available for harsh conditions).
Weight: Approx. 40–50 kg (depending on configuration).
Dimensions (H x W x D): Approx. 600 x 400 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.
