Parameters: Model Number: ABB E1N1250 R1250 PR121/P-LSI WMP 3P Rated Voltage: 400 V AC (Three-phase) Rated Current: 1250 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 protection against sustained overcurrents. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, for short-circuit protection, preventing damage from transient overcurrents. Instantaneous Protection (I): Provides immediate disconnection for severe short-circuit conditions to protect sensitive equipment from high fault currents. Ground Fault Protection (G): Detects leakage currents or ground faults and isolates the faulty section, improving electrical safety. Thermal Overload Protection: Protects motors from overheating by monitoring the system’s temperature and preventing extended overcurrent conditions. Wide Motor Protection (WMP): Ensures adaptive protection tailored to motor applications, optimizing protection parameters based on specific motor types and operational conditions. Breaking Capacity (Icu): 50 kA at 400 V, ensuring the breaker can safely handle high fault currents and disconnect the system in fault conditions. Mounting Type: DIN rail or panel mount for easy integration into electrical control systems, such as motor control centers (MCCs) or distribution panels. Degree of Protection: IP20 (suitable for indoor environments; optional external protection kits available for harsh environments). Weight: Approx. 15–20 kg (depending on configuration). Dimensions (H x W x D): Approx. 400 x 250 x 180 mm (subject to configuration). Control Voltage: 24 V DC (external supply required for control and communication features). Modbus RTU Communication (Optional): For remote monitoring and diagnostics, enabling real-time system health checks and fault detection via PLC or SCADA systems. Auxiliary Contacts (Optional): Available for use in control systems, providing feedback and fault signaling to external systems.
