Ground Fault Circuit Interrupter (GFCI), also known as residual current devices, are designed to protect people from electrical shocks resulting from an electrical shock. GFCI has been widely used in residential and commercial applications for many years. In this article, we will discuss the application field and working principle of PGFI-1445N, one of the most commonly used GFCI products.

PGFI-1445N is a two-pole GFCI device that is widely used in both residential and commercial applications. In residential settings, PGFI-1445N is commonly used in bathrooms, garages, and outdoor kitchens. It is typically installed near electrical outlets and other points of contact to protect people from shock and electrocution in wet and damp environments. In commercial applications, PGFI-1445N is commonly installed in classrooms, laboratories, workshops, and near hazardous areas for extra protection in these potentially dangerous locations.

The working principle of PGFI-1445N is based on a current sensing principle, which is used to detect the presence of a leakage current in the circuit. When the device detects a leakage current above a certain threshold, it initiates a response by opening the circuit, breaking the current flow and thus providing protection to the user. This is achieved by using an integrated circuit design with a current-sensing coil, a comparator, and a relay. The current-sensing coil is sensitive to small changes in the load current. This allows the device to detect even the slightest leakage current in the circuit.

The PGFI-1445N also features a built-in test/reset switch, which is used to test the device’s operational ability. It is important to regularly verify that PGFI-1445N is functioning properly. This is done by inserting the test/reset switch into the test/reset port, and then pushing the switch\'s “trip” button. If the device works correctly, then it will cause an interrupt in the circuit and reset the switch.

PGFI-1445N is designed to provide a maximum protection against electric shocks. This protection is achieved by quickly detecting a leakage current and opening the circuit in the event of unexpected high leakage current. The device is capable of detecting even small currents, making it reliable and efficient in providing protection against electric shocks. PGFI-1445N is easy to install, and is widely used in both residential and commercial applications.
