Phoenix Contact 2907919 Surge Protection Device – PLT-SEC-T3-230-FM-UT

The Phoenix Contact PLT-SEC-T3-230-FM-UT is a compact, pluggable Type 2/3 surge protection device designed for single-phase power networks. It features both visual fault indicators and remote signaling, supporting protection modes for L-N, L-PE, and N-PE. This DIN rail-mounted device offers robust protection for residential, commercial, and industrial systems.

With a nominal voltage rating of 230 V AC/DC, low residual voltage levels, and high-speed response times, it protects sensitive equipment from transient overvoltages caused by surges and indirect lightning strikes.
