iPRF1, PRD1 Type 1 Overvoltage Protection Devices

Product Information

 

type 1 and type 1 + 2, surge arresters (IEC 61643-11: 2011, EN 61643-11: 2012)

 

Protection of electrical equipment against direct sunlight spillover (tested and graded according to standardized 10 / 350μs current wave)

 

It is specified by IEC / EN 62305-2 in commercial and industrial buildings protected by a lightning guard or braided cage,

 

Pulse flow, Iimp

iPRF1 12.5 kA for 12.5r: suitable for buildings with protection levels III and IV

25 kA for PRD1 25r and PRD1 Master, 35 kA for PRF1 Master: suitable for buildings with protection levels I and II

cutter, fuse or circuit breaker: look at the coordination chart

iPRF1 12.5r and PRD1 25r are in type 2 class (8/20 μs) and maintain the electrical equipment by distributing the voltage fluctuation on a regular basis

230 / 400V 50 / 60Hz networks with grounding system TT, TN-S, TN-C. Ayrica PRF1 Master is also suitable for 440V IT grounded system.

 

Applications

Protection of electrical installations against inductive or conductive fluctuations caused by direct cycling of all industrial and commercial buildings
