Surge Protectionwith EMI-filterEPF 230V/16A-TrEPF 230V/25A-TrSurge protective Device class II, SPD type T2 , category C, with filterOvervoltage protection in single pole TN-net systems with very sensible electronicsEPF 230V/16A-Tr• Surge protection SPD with low-pass EMI-filter• Leakage current free grounding to avoid grounder corrosion• Coordination with upstream installed class I (SPD type 1) lightning protective SPDLEUTRON PowerPro BCD possible• High impulse current capability• Function control and damage monitoring by LEDProduct descriptionEPF 230V/16A -Tr and EPF 230V/25A -Tr are designed to protect sensible electronic equipments and againstsurge voltages caused by SEMP and LEMP as well as HF-interferences, caused by the electromagnetic field ofan lightning stroke. Available for power consumption up to 16A and 25A. The surge impulse current capabilityis up to 25kA (8/20µs).The new designed protection circuit with filter contains additionally to the coarse and fine protection by Varistors(MOV) an optimized decoupling between both protection stages.This decoupling is made by a combinationof Ohms resistant, inductive resistant (differential mode and common mode filter). By these, a low-pass behaviouris achieved.The SPDs are fitted with a thermal protection NC contact, which respond if the varistor exceed a certain level oftemperature due to thermal overload.These thermal protection contact works in such a way, that they only cutoff the SPD from the power supply whilst the electrical equipment will not suffer any functioning failure; in thatcase the green signal LED will go out.Before this happens, the remote contact (optional) inside the housing will open and signalise that the SPD hasto be replaced.The protective circuit is installed in an easy-to-handle compact housing with snap-on clips for 35 mm DIN railmounting with multifunctional screw terminals for wire and bus-bar connections.ApplicationSurge voltage protection of sensitive electronic devices and/or electronic systems like GSM stations againsthigh frequency surges caused by atmospheric disturbances, as well as against self created harmonic interferences.To be installed at the boundary 1-2, acc. to the lightning zones concept of VDE 0185-305-1-4 (IEC62305 part 1-4).Protects People and Valuables
