The CITEL DS134RS-230 surge protector safeguards three-phase electrical installations against lightning currents and transient overvoltages. It combines Type 1 and Type 2 protection and uses MOV (Metal Oxide Varistor) technology.
It is suitable for 230/400 V AC (3P+N) networks and mounts on a 35 mm DIN rail. The removable modules simplify replacement, while the visual status indicator and remote signalling contact allow the device to be monitored. It is used in photovoltaic systems, main electrical panels, industrial installations, and commercial buildings.
