Parameters:
Model Number: ABB E3S2000 R2000 PR121/P-LSI 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, ensuring that motors are not damaged by prolonged overcurrents.
Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, for short-circuit protection to protect against fault conditions without causing unnecessary trips.
Instantaneous Protection (I): Provides instantaneous disconnection in the event 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 damage and ensure safety.
Thermal Overload Protection: The breaker monitors the temperature of the system and protects motors from overheating, reducing the risk of damage due to sustained overload conditions.
Breaking Capacity (Icu): 65 kA at 400 V, ensuring the breaker can interrupt high fault currents and clear faults safely without damaging 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 protection kits available for harsh conditions).
Weight: Approx. 45–50 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).
Modbus RTU Communication (Optional): Enables remote monitoring and fault diagnostics via PLC or SCADA systems, providing real-time system health tracking.
Auxiliary Contacts (Optional): Available for use in control systems to provide feedback, signaling faults, or integrating with safety systems.
