Glossary as bellow:

VN

Nominal Varistor  Voltage

Voltage, at specified d.c. current used as a reference point in the component characteristic.

IL

Leakage Current

Measuring at 75% of varistor voltage

UCT

Upper Category Temp.

Max. ambient temp. for which a varistor has been designed to operate continuously.

LCT

Lower Category Temp.

Minimum ambient temp. at which a varistor has been designed to operate continuously.

Max. Peak Current

Max. current per pulse, which may be passed by a varistor at an ambient temp. of 25 °C, for a given number of pulses.

VC

Clamping Voltage

Peak voltage developed across the varistor terminations under standard atmospheric conditions, when passing an 8/20 μs class current pulse.

Voltage Proof

Max. peak voltage, which may be applied under continuous operating conditions between the varistor terminations and any conducting mounting surface. (Applicable only to insulated varistors)

CV

Capacitance

Capacitance across the MOV measured at a specified frequency and voltage

Vac

Max. Continuous a.c. Voltage

Max. a.c. r.m.s. voltage of a substantially sinusoidal waveform (less than 5% total harmonic distortion) which can be applied to the component under continuous operating conditions at 25 °C.

Vdc

Max. Continuous d.c. Voltage

Max. d.c. voltage (with less than 5% ripple) which can be applied to the component under continuous operating conditions at an ambient temp. of 25 °C.

In

Nominal Discharge Current

Crest value of the current through the SPD having a current waveshape of 8/20 μs.

Imax

Max. Discharge Current

Crest value of a current through the SPD having an 8/20 μs waveshape and magnitude according to the manufacturers specification. Imax is equal to or greater than In.
