From WJ Furse, these lightning surge arrestors are designed for use on twisted-pair lines found in process control equipment, modems and communications interfaces. These surge protectors offer full mode protection with very low let through voltage (to BS EN 62305) between all lines. The full mode design allows for the continued operation of protected equipment while also handling partial lightning currents. ESP series surge protectors offer repeated protection in lightning intense environments and are encased within a strong, flame retardant ABS housing.

These surge protectors should be installed closely to the system's earth start point. They should be connected in series with the data communication or signal line close to the equipment that is being protected, such as the control panel. Alternatively, these surge protectors should be installed where the signal line enters or leaves the building. Surge protectors should be installed within a separate enclosure or in an existing enclosure.
