The equipment is compatible with 50 Hz, 500 V and below, load currents ≤ 250 A three-phase three-wire, three-phase four-wire, and three-phase five-wire distribution systems, enabling distribution system control, residual current protection, and multiple safeguards against motor overload, short circuits, phase loss, etc. At the same time, it provides comprehensive safety protection against circuit overloads, short circuits, leakage currents, overvoltages, and other potential hazards. With an aesthetically pleasing appearance and reliable, safe operation, it serves as a standard foundational component for low-voltage distribution projects across all sectors.
Working Principle
The low-voltage distribution box builds a complete low-voltage distribution control system through its internally integrated electrical components. Once connected to the low-voltage distribution system, it can uniformly distribute, regulate, and precisely measure incoming electrical energy. By relying on circuit breakers, fuses, and contactors, it achieves circuit switching and load control, while paired with residual current, overvoltage, and phase-loss protection elements to monitor circuit operating conditions in real time. When the distribution circuit or motor encounters abnormal conditions such as overload, short circuit, leakage current, phase loss, or overvoltage, the device swiftly triggers protective mechanisms, automatically disconnecting faulty circuits to prevent equipment damage and electrical safety risks. The JXF control box is precisely tailored to common low-voltage distribution scenarios, with a standardized circuit layout that matches multi-specification three-phase distribution systems, ensuring stable, orderly, controllable, and measurable operation of low-voltage distribution systems.
