Wave breaker function

In the case of spark-gap-based type 1 arresters, the entire current flows through the type 1 arrester during the discharge process. Like a wave breaker, the incoming energy is greatly broken down, which significantly relieves the downstream SPDs. All type 1 arresters in the Red/Line product range feature the WBF wave breaker function.

Technical data

SPD according to EN 61643-11 / IEC 61643-11 type 1 + type 2 / class I + class II
Max. continuous operating voltage (a.c.) (UC ) 255 V (50 / 60 Hz)
Lightning impulse current (10/350 µs) [L1+L2+L3-PEN] (Itotal ) 75 kA
Lightning impulse current (10/350 µs) [L-PEN] (Iimp ) 25 kA
Voltage protection level (UP ) ≤ 1.5 kV
Max. backup fuse up to IK = 25 kArms 315 A gG
