Ground Fault Circuit Interrupters (GFCIs) are devices used to provide greater safety in commercial and residential outlets by quickly disconnecting power when a ground fault or fault current is detected. The PGFM-111-B-A1-188 is a GFCI designed for outdoor use in hazardous locations. It is designed to protect things like water pumps, construction sites, and other outdoor locations from over-voltage and the dangers created by sudden electrical spikes.

The PGFM-111-B-A1-188 is designed to cut off power when it detects a ground fault. This happens when current flows through an unintended path, such as through a person or object, creating a potential safety hazard. The PGFM-111-B-A1-188 has twoinputs, one for line voltage and one for ground, and two outputs, one to activate the circuit and one to indicate the fault condition. When the device detects a ground fault current, it interrupts the power supply, automatically cutting off power to the load.

The PGFM-111-B-A1-188 has a trip current rating of 10 mA, which means it will trip and disconnect power if the current that is sent through the device is greater than 10 mA. The device also has a lockout delay of 0.25 s for line-to-ground faults and an operational temperature of between –20° C and 40° C. Additionally, the device is UL 943-C certified, which means it has been tested and approved to meet industry safety standards.

The PGFM-111-B-A1-188 is typically used in harsh environmental conditions, such as in construction and industrial sites, and is also suitable for installation in damp areas. It comes with a LED reset indicator that lights up to indicate that the device has triggered and the power has been cut off.The device is composed of a thermal-magnetic trip element, which is designed to sense sudden overloads or shorting of the line, a neutral conductor, and a ground terminal. The thermal-magnetic trip element reacts fast to the sudden current changes and prevents the fault from progressing further. When triggered, the trip element cuts off the power supply, saving the appliances connected from being damaged.The PGFM-111-B-A1-188 is designed for outdoor use and features a weatherproof enclosure that is designed to protect it against physical shock, dust, and water. The device is also surge-protected and uses high-efficiency current sensors for fast response times.Overall, the PGFM-111-B-A1-188 is a reliable ground fault circuit interrupter that is designed for outdoor use in hazardous environments. It is UL 943-C certified and meets industry safety standards. The device is designed to quickly disconnect power when it detects a ground fault, protecting appliances and people from the potential dangers of electrical spikes, overloads, and shorting.
