The DAC15C Type 2 or Type 3 Compact plugable surge protectors (SPD) are intended to be connected at the TGBT or divisional panel level. Their compact format allows them to be installed in very small spaces. The DAC15C SPDs are available have a discharge capacity of 15 kA, in single-phase or 3-phase configuration and with various voltages in order to protect any type of networks. Based on varistance technology equipped with disconnector and associated indicator, these SPD ensure maximum protection efficiency, flow capacity and reliability.
