The Baseline BL-LA01 Direct-Burial Surge Arrestor provides robust over-voltage protection for two‑wire irrigation and lighting control paths. Designed for permanent underground ins tallation, the fully sealed unit diverts damaging transient energy to earth ground before it reaches controllers or two‑wire devices. Protects two‑wire paths — reduces excessive electrical charges from lightning and other surges. Direct-burial design — fully sealed, submersible housing rated for underground installation. Simple installation — connects inline to the two‑wire; polarity must be maintained for red and black leads. Twin-stage protection — two levels of surge suppression that clamp at about 60 volts in under 1 microsecond. Included leads — supplied with 23‑inch PVC‑jacketed lead wires for two‑wire and ground connections. Typical coverage — protects a two‑wire backbone to approximately 300 feet from the controller in common topologies. Install the BL-LA01 in a valve box or other protected location; connect the red and black leads to the two‑wire and the green lead to a properly installed ground rod or plate. Follow the Baseline installation guide for grounding, connector selection, and testing procedures to ensure reliable, long-term operation. Show more
