Where it is used
Install it at the main distribution board or sub-boards of homes, offices, factories, telecom sites and solar systems to protect electronics, drives and controllers. See all items in our Surge Protection Devices (SPD) range.
How to choose the right one
Use 40 kA for normal distribution boards and 65 kA for main boards in exposed or lightning-prone sites. Use 2P (or 1P+N) for single-phase and 4P (or 3P+N) for three-phase supply; pick 275V for single-phase 230V and 385V for three-phase 400V. Always fit a suitable MCB or fuse in front of the SPD.
