AC Surge Arresters 3P 10KA~20KA Surge Protection Device Feature:
- The core parts are metal oxide varistor components with high discharge capacity.
- For using in the lightning protection zones concept at boundary 1-2.
- Low residual voltage and quick response.
- Surge Protection Devices (referred to as SPD’s) provide protection against surge current resulting from direct or indirect lightning strikes or similar surge voltages.
- Reliable control.
- The SPD functions to conduct the surge voltage / current to earth and effectively prevents the destruction of downstream equipment.
- With remote signaling contact for control device.
- Plug in replacement module unit allows for easy replacement when necessary.
- Fault indication via red mark in the inspection window.
