Ground Fault Circuit Interrupter (GFCI) devices are an essential protection device, used in all residential, commercial, and industrial settings. The goal of these devices is to provide safe, reliable, and efficient protection against the risk of electric shock from ground faults. By sensing the presence of stray electricity when it shouldn\'t be present, GFCIs instantly shut off the associated power circuits, effectively eliminating the risk of electric shock to personnel.

The PGFI-A040KYST25 is a Ground Fault Circuit Interrupter (GFCI) device with a 30 mA trip threshold current. It is a single-phase, three-wire circuit interrupter, incorporating a thermal-magnetic circuit breaker, and can be used to provide protection in a variety of different applications. The device is UL listed and complies with the requirements outlined in UL standard 943 and other applicable UL standards. The device is also listed to CSA C22.2 No. 144-M1991, and complies with the requirements of the Canadian Electrical Code.

The PGFI-A040KYST25 is most commonly used in residential and light commercial settings. It is designed to provide protection of people from electric shock and property damage from arcing faults. The device is typically installed on individual circuit breakers in a panel, and can be used as a replacement for standard circuit breakers. It is also often used in outlets, junction boxes, and other areas where the main supply voltages are greater than 250V AC.

The PGFI-A040KYST25 is designed for use in both indoor and outdoor applications. It can be used in a variety of different wiring configurations, including single-phase, three-wire, and four-wire systems. This flexibility allows the device to be used in any situation that requires GFCI protection.

The working principle of the PGFI-A040KYST25 is based on the principle of ground fault detection and interruption. The device uses two closely-monitoring coils, or toroids, to detect any imbalance in the current flowing through the system. When a ground fault is sensed, the device trips, shutting off the associated power circuits. The device is designed to trip within 30 mA of ground fault current, ensuring safe and reliable protection against electric shock.

The PGFI-A040KYST25 is a highly reliable and versatile ground fault circuit interrupter device, providing protection in a wide range of applications. Its 30 mA trip threshold ensures that any stray electrical current is detected and interrupted before it can cause electric shock or other injury, providing safe and efficient protection for personnel and property in residential, commercial, and industrial settings.
