Modern electronics and circuitry used in computing, communications and control/alarm installations are highly susceptible to damage from lightning surges and other transient over-voltages. ERICO specialises in providing protection at two points:

• At the point of entry of power lines to buildings, Shunt Protection Devices (SPDs) rapidly limit transient over-voltages under surge conditions and direct the excess lightning energy safely to ground.

• For sensitive electronic equipment Surge Reduction Filters (SRF’s), use suitably designed low pass filter technologies which follow primary SPD’s. They reduce the peak residual voltage and drmatically reduce the rate of current and voltage rise to downstream equipment.

The Critec DIDLINE family of SPDs and DSFs provide protection from transients on power lines with convenience of easy installation on 35mm DIN rail mouinting.

ERICO’s award winning Transient Discriminating (TD) products use high performance hybrid technology to provide a low residual voltage to equipment with high tolerance to sustained over-voltage conditions.
