Product overviewDLC compact surge protective devices (SPDs) protect terminal equipment connected to industrial buses, telecommunication lines or signalling systems from lightning and transient overvoltages. These non-pluggable (monobloc) units are designed for 1-pair plus shield applications and are mounted on a symmetrical 35 mm DIN rail inside customer panels. Multiple types (D2, D3, D3G) are available to cover floating or full-mode and signalling-ground protection requirements.
