Parameters: Model Number: ABB E3N3200 R3200 PR121/P PR122/P Rated Voltage: 400 V AC (Three-phase) Rated Current: 3200 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 prolonged overcurrents. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, to protect against short-circuit faults. Instantaneous Protection (I): Provides immediate disconnection during severe short-circuit conditions to protect sensitive equipment. Ground Fault Protection (G): Detects leakage currents or ground faults, isolating faulty circuits and enhancing safety. Thermal Overload Protection: Continuously monitors the temperature of the system and adjusts protection to prevent overheating, extending equipment life. Breaking Capacity (Icu): 50 kA at 400 V, ideal for high-fault conditions, ensuring quick and safe disconnection to protect equipment. Mounting Type: DIN rail or panel mount, allowing easy installation in electrical control panels or motor control centers (MCCs). Degree of Protection: IP20 (indoor use; optional external protection kits available for harsh environments). Weight: Approx. 25–30 kg (depending on configuration and options). Dimensions (H x W x D): Approx. 550 x 350 x 250 mm (varies depending on specific configuration). Control Voltage: 24 V DC (external supply required for control and communication functions). Modbus RTU Communication (Optional): Enables remote monitoring, diagnostics, and fault detection via PLC or SCADA systems. Auxiliary Contacts (Optional): Available for integration with control systems for feedback or signaling purposes.
