The differential current block from Schneider Electric, model Vigi NG125, is a highly advanced residual current protection block designed for use in electrical installations. With a rated current of 63A and a rated residual current range of 300 to 3000mA, this device provides reliable protection against leakage currents. The block is suitable for mounting on a DIN rail and complies with the IEC/EN 61009-1 standards as well as VDE certification, underscoring its safety and reliability. The thermomagnetic tripping unit ensures precise response to leakage currents, while a mechanical indicator on the knob signals the tripping. The differential current block is also equipped with a test button that allows for regular functional testing. Optional auxiliary modules such as operational current relays and fault indication switches can be added to enhance functionality.
