The DAC40CS series are compact type 2 or type 3 surge protection devices designed to protect single or multi-phase systems. They are equipped with a pluggable protection module and are designed for DIN rail mounting. The DAC40CS series are available for supply voltages of 120V, 230V or 400V and all common mains types (TN, TNC, TNS, TT). The protection circuit consists of high performance varistors with a thermal break and error signaling. A potential-free contact serves for the connection of a remote signaling.
