Ground Fault Circuit Interrupters (GFCIs) are electro-mechanical devices that can detect and protect an electrical system and its components from dangerous electrical events. They are commonly used in residential and commercial applications to protect against shocks and other related hazards. The PGFI-M04 is a type of GFCI designed for industrial applications.

A Ground Fault Interrupter works by measuring the current that flows through each of its wires. If the current flowing through one of the wires is more than twice the amount flowing through the other three wires, the GFCI will immediately shut off the power supply to the system, preventing potential damage and injury. This type of device is also known as a differential current interrupter.

The PGFI-M04 is a robust, high-performance GFCI, capable of operating in environments with extended temperature ranges and severe vibration. It is designed for outdoor and hazardous industrial areas and for applications that require a dedicated ground fault circuit. The device is versatile and comes with three common ratings: 30mA, 300mA and 1500mA.

In operation, the PGFI-M04 works in an analogous manner to the traditional GFCIs. It monitors the current in each of its four wires and compares the two opposing currents. If the difference between them is more than twice the rated current of the device, then it will disconnect the power supply to the system. This provides additional safety, as it helps to protect against electric shock hazards.

The PGFI-M04 is designed to detect even a small ground fault current. It has a wide dynamic range and can detect faults in the range from 0.1mA to 1500mA. This allows it to offer greater protection even in situations where the ground fault current is too small to be detected by other GFCIs. In addition, the device is designed to reduce false trips, ensuring that it only trips when there is a substantial risk of electric shock.

The PGFI-M04 also features a unique built-in self-test function that regularly tests the device operation, ensuring that it is always working correctly. The self-test feature ensures that any minor faults that develop over time are immediately identified and rectified. The device is also CE-rated and meets stringent international safety standards such as UL1053 and IEC-60870-5-1.

The PGFI-M04 is a rugged and reliable Ground Fault Circuit Interrupter suitable for use in a wide range of industrial applications. Its advanced features ensure that it can consistently detect ground fault currents and protect against the risk of electric shock. This makes the device an ideal choice for environments where safety is of paramount importance.
