AFCI Types and Product Categories
The table below contains the current UL AFCI Product Categories as well as a similar product referred to as a leakage-current detection and interruption (LCDI) device. These product categories are tabulated by CCN (Category Control Number), product category name and AFCI or LCDI Type definition.
By clicking on the CCN you will be linked to the UL Online Certifications Directory database which will provide you with the UL Guide Information for the category and all current Listings under that Product Category.
AVYI is the main category that all AFCI sub-categories fall under. It contains the general information pertinent to all AFCI categories and sub-categories.
CCN | Product Category and Type Definition |
AVYI (Main Guide) | Arc Fault Circuit Interrupters (AFCI) - A device intended to mitigate the effects of arcing faults by functioning to de-energize the circuit when an arc-fault is detected. |
These following types of AFCIs are intended for permanent installation in a branch circuit (or feeder where noted).
CCN | Product Category and Type Definition |
AVZQ | Arc Fault Circuit Interrupters, Branch/Feeder Type - A device intended to be installed at the origin of a branch circuit or feeder, such as at a panelboard. It is intended to provide protection of the branch circuit wiring, feeder wiring, or both, against unwanted effects of arcing. This device also provides limited protection to branch circuit extension wiring. It may be a circuit-breaker type device or a device in its own enclosure mounted at or near a panelboard. |
AWAH | Arc Fault Circuit Interrupters, Combination Type - An AFCI which complies with the requirements for both branch/feeder and outlet circuit AFCIs. It is intended to protect downstream branch circuit wiring and cord sets and power-supply cords. |
AWBZ | Arc Fault Circuit Interrupters, Outlet Branch Circuit Type - A device intended to be installed as the first outlet in a branch circuit. It is intended to provide protection to downstream branch circuit wiring, cord sets, and power-supply cords against the unwanted effects of arcing. This device also provides protection to upstream branch circuit wiring. It is intended to be provided with or without receptacle outlets. |
AWCG | Arc Fault Circuit Interrupters, Outlet Circuit Type - A device intended to be installed at a branch circuit outlet, such as at an outlet box. It is intended to provide protection of cord sets and power-supply cords connected to it (when provided with receptacle outlets) against the unwanted effects of arcing. This device may provide feed-through protection of the cord sets and power-supply cords connected to downstream receptacles. |
The following types of AFCIs are portable devices and may be incorporated into appliances or utilization equipment.
CCN | Product Category and Type Definition |
AWAY | Arc Fault Circuit Interrupters, Cord Type - A plug-in device intended to be connected to a receptacle outlet. It is intended to provide protection to the power-supply cord connected to it against the unwanted effects of arcing. The cord may be integral to the device. The device has no additional outlets. |
AWDO | Arc Fault Circuit Interrupters, Portable Type - A plug-in device intended to be connected to a receptacle outlet and provided with one or more outlets. It is intended to provide protection to connected cord sets and power-supply cords against the unwanted effects of arcing. |
The following device is similar to AFCIs, they are referred to as leakage-current detection and interruption (LCDI) devices.
CCN | Product Category and Type Definition |
ELGN | Leakage-Current Detection And Interruption (LCDI) � This is a device provided in a power supply cord or cord set that senses leakage current flowing between or from the integral cord conductors and interrupts the circuit at a predetermined level of leakage current. |
