Description:
The Delta Lightning Arrestor LA302-DC is a lightning surge arrestor that can handle high current surges too large for an MOV or capacitor. It provides protection to electrical equipment by reducing problems due to lightning strikes or power surges. Unit can react in as little as five nanoseconds and begins to conduct when voltage rises above the normal line voltage after a specific time delay and handle an unlimited number of surges.

Use the LA302-DC for surge protection on wires coming from a PV array, DC wind generator or DC hydroelectric turbine. Use the LA302-R for AC circuits. An LA602-DC is also available for higher voltage applications. All units are waterproof.
