Parameters: Model Number: ABB E4S4000 R4000 PR122/P-LSIG 4P 4000A Rated Voltage: 400 V AC (Four-pole, Three-phase system) Rated Current: 4000 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, preventing equipment damage from prolonged overcurrents. Short-Time Protection (S): Adjustable from 3 to 10 times rated current, with a time delay, to protect against short-circuit conditions and to avoid unnecessary trips. Instantaneous Protection (I): Provides instantaneous disconnection for high fault currents, ensuring fast protection against severe short-circuit conditions. Ground Fault Protection (G): Ground fault protection (LSIG) detects leakage currents or faults and isolates the faulty section, providing enhanced safety. Thermal Overload Protection: Continuously monitors the temperature of motors and equipment, adjusting protection to prevent overheating and ensure the longevity of the system. Breaking Capacity (Icu): 65 kA at 400 V, ensuring the breaker can interrupt high fault currents and safely clear faults without damaging the system. Mounting Type: DIN rail or panel mount, making it versatile for use in motor control centers (MCCs), distribution boards, and control panels. Degree of Protection: IP20 (suitable for indoor environments; external protection kits available for harsher, outdoor conditions). Weight: Approx. 50–60 kg (depending on configuration). Dimensions (H x W x D): Approx. 650 x 450 x 300 mm (varies with configuration). Control Voltage: 24 V DC (external supply for control and communication features). Modbus RTU Communication (Optional): Enables remote monitoring, diagnostics, and fault detection through PLC or SCADA systems, allowing real-time system status checks and fault tracking. Auxiliary Contacts (Optional): Available for use with control systems for signaling faults, status monitoring, or integration with safety systems.
