DAC40CS products are compact, Type 2 or type 3 surge protection (SPD) devices designed to protect single-phase or 3-phase systems. They are designed for DIN rail mounting and the SDP cartridges are replaceable. The DAC40CS series are available for supply voltages from 75 Vdc to 350 Vdc. The protection circuit consists of high energy varistances, with a thermal disconnection system. The SPD includes status signalling via a visual indicator and a remote signalling system (optional).
