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.
The ABB E4S4000 R4000 PR122/P-LSIG 4P 4000A is a high-performance, four-pole (4P) motor protection circuit breaker (MPCB) designed for heavy-duty applications in industrial and commercial environments. This model is part of ABB's E4S series, providing advanced protection for high-current motors, transformers, and electrical circuits. With a rated current of 4000 A, this breaker is designed to protect large three-phase electrical systems and other critical equipment from various types of electrical faults, including overload, short-circuit, ground faults, and thermal damage.
