The NG125 is an earth leakage add-on block, specifically the Vigi NG125 model, designed for enhanced electrical safety. This device is a 4-pole configuration, making it suitable for three-phase systems with a neutral. It has a rated current of 125A, indicating its capacity to handle substantial electrical loads. The sensitivity of this earth leakage protection is set at 30mA, ensuring rapid response to even small leakage currents. This sensitivity level is crucial for preventing electrical shocks and minimizing the risk of fire. The Vigi NG125 add-on block works in conjunction with a compatible circuit breaker to provide comprehensive protection against overloads, short circuits, and earth leakage faults. Its primary function is to detect earth leakage currents and quickly trip the circuit, disconnecting the power supply to prevent potential hazards. This device is commonly used in industrial, commercial, and residential applications to safeguard people and equipment from electrical faults. By adding this earth leakage protection, electrical systems become significantly safer and more reliable.
