Lightning- and Surge Protection EP 802/20kA-Tr EnerPro 2-pole Lightning- and Surge Protective Device 20kA (max. 40kA) For protection of DC- applications and Photovoltaic Systems • • • • • • Lightning- und Surge Protection of DC-mains and photovoltaic solar systems 20kA heavy duty arrester (MOV) Protection circuit molded in water- and corrosion resistant polyurethane Monitoring of line interruption and function control by green LED Large size multifunctional terminals 2-pole, rigid 2-mod. DIN housing for snap-on 35mm DIN-rail Product description LEUTRON SPD type EP 802/20kA-Tr serves as a Lightning and Surge Protective Device (SPD) installed at the power supply side of DC equipments and systems. One SPD protects 2 lines (+ and -). This LEUTRON - EnerPro SPD is equipped with a safety disconnection device which will response safely and cut off the SPD from net, if the built-in MOV would be thermally overloaded by a too high leakage current. In such case, the green operating indication LED will extinguish and the SPD has to be replaced. The thermic coupled remote signal contact (option) signalise that the SPD was overloaded and should be replaced before the SPD is cut-off from net, because of safety reason. The protective circuit is completely molded in Polyurethane and is built in an easy to install Polycarbonate housing to snap on a 35mm DIN-rail (EN50022). Large multifunctional terminals for connection of bus-bars and conductors for easy and safe wiring together with other DIN rail mounted devices. Application This robust and rigid protective device serves to protect DC- and photovoltaic systems against damages caused by lightning surges. If used in photovoltaic systems (PV) the EP 802/20kA-Tr should be preferred to install in the PV-generator connection box. Because the inverse rectifier probably is installed several meters far away, it is unprotected. Therefore SPDs of same types as installed at the generator output has to be installed at the DC-side of the inverse rectifier too. Protects People and Valuables Technical Data: Application 2-pole lightning SPD with function indication by LED. Mostly used for protection of Photovoltaic systems to be installed in the generator connection box and at the DC-input of inverse rectifiers.
