Product Description
Delta LA602DC
3‑Wire • 1100VDC • DC Lightning Arrestor
High‑energy Delta DC Lightning Arrestors provide rapid‑response protection for solar and wind power systems exposed to lightning activity. The Delta LA Series is engineered to handle massive surge events—up to 50,000 amps—diverting destructive energy safely to ground.
All current Delta DC arrestors now include the formerly optional vent valve. In the event of a direct strike, this safety vent opens at the bottom of the enclosure to prevent case rupture.
While no device can guarantee 100% lightning protection, the LA602DC significantly reduces failures caused by lightning, voltage spikes, and power surges. This model is ideal for high‑voltage and grid‑tie photovoltaic systems.
Delta Arrestor Features
- Non‑conductive base prevents shock hazards if the unit fails
- Fails without producing carbon dust that could damage nearby equipment
- Always fails “clear,” allowing continued system operation
- Silicon‑based design provides fast response and low conduction resistance
- Handles numerous high‑energy surges and half‑cycle spikes before failure
- Extra‑long leads for easier installation
- Includes locknut and bushing
- Available in multiple voltages and pole configurations
