DAC40CS-31-275

Remote signaling of disconnection: output on changeover contact

The DAC40CS-31-27 Type 2 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 DAC40C Type 2 SPDs are available have a discharge capacity of 40 kA, in single-phase or 3-phase configuration and with various voltages in order to protect any type of networks.
