Applications:

The ESP 415/III/TNS is ideal for use on three-phase mains supplies and power distribution systems, providing protection against partial direct or indirect lightning strikes. It is particularly suitable for environments with Class III or IV Lightning Protection Systems (LPS) or exposed overhead three-phase power lines where no LPS is installed.

Installation:

Designed for parallel installation in the main distribution board, the protector should be connected with minimal lead length. It is suitable for attachment to a 35 mm top hat DIN rail and should be fused appropriately, ensuring discrimination with upstream devices.

Invest in the ESP 415/III/TNS Three Phase Protector 415V to ensure the safety and longevity of your electrical systems. With its advanced features and robust design, it offers reliable protection against transient overvoltages, safeguarding your equipment and operations.
