Type 2 surge protection unit DACN15 series

type 3for transient current protectionfor electrical installations

The DACN15-P surge protectors are designed for single-phase low-voltage AC installations. They provide Type 2+3 protection with a nominal discharge current (In) of 5 kA and a maximum discharge current (Imax) of 15 kA. In accordance with IEC standards, units with In = 5 kA can be installed in main or secondary distribution panels. The DACN15-P11-275/INV variant features an inverted base for bottom wiring to suit specific installation constraints.
