Ceramate offers an extensive range of Varistors for transient voltage suppression


Designed to protect voltage sensitive products against damage, Ceramate's GNR series of high energy absorption, metal oxide varistors provide a convenient and simple solution to transient suppression.

The basic principle of a varistor is to sense and limit transient voltage spikes. A varistor remains high impedance (non-operative) during normal standby use. However, when a voltage spike is encountered the impedance rapidly drops to a very low level, clamping the transient voltage to an acceptable level. The varistor absorbs the unwanted energy thereby protecting voltage sensitive devices against damage.

Ceramate's GNR series covers a broad range of varistor voltages, from 18V to 1100V, with each voltage offering a selection of energy absorption values. A variety of factory options, such as alternative lead styles, non-flammable types and taped product further extends the range.

Suitable for 'across the line' applications, the GNR series has UL, CSA and VDE approvals.
