Product Code 2DCAFL5
The 2DCAFL5 is designed to protect constant current circuits that supply power to airfield lighting systems from both direct and indirect lightning strikes. Its terminal design allows it to be easily retrofitted into existing circuits.
The device consists of two metal oxide surge arresters that are connected in parallel with supply cables to be protected. The terminals are designed so that existing cables can be cut in a convenient location and connected to the device, without having to use a spur or splice. The 2DCAFL5 should be installed close to the control equipment, in a location where a good earth connection is available.
