2. Surge protector - Wikipedia

   en.wikipedia.org/wiki/Surge_protector

   Surge Protection Device (SPD) for installation in a low-voltage distribution board. A surge protector (or spike suppressor, surge suppressor, surge diverter, [1] surge protection device (SPD) or transient voltage surge suppressor (TVSS) is an appliance or device intended to protect electrical devices in alternating current (AC) circuits from voltage spikes with very short duration measured in ...

3. Transient-voltage-suppression diode - Wikipedia

   en.wikipedia.org/wiki/Transient-voltage...

   A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond, but in a practical circuit the inductance of the wires leading to the device imposes a higher limit.

4. Varistor - Wikipedia

   en.wikipedia.org/wiki/Varistor

   Modern varistor schematic symbol, which is the same as a thermistor symbol [ 1 ] A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. [ 2 ] It has a nonlinear, non- ohmic current–voltage characteristic that is similar to that of a diode.

5. Inrush current limiter - Wikipedia

   en.wikipedia.org/wiki/Inrush_current_limiter

   An inrush current limiter is a component used to limit inrush current to avoid gradual damage to components and avoid blowing fuses or tripping circuit breakers. Negative temperature coefficient (NTC) thermistors and fixed resistors are often used to limit inrush current. NTC thermistors can be used as inrush-current limiting devices in power ...

6. Arc suppression - Wikipedia

   en.wikipedia.org/wiki/Arc_suppression

   Arc suppression. Arc suppression is the reduction of the electric arc [1][2][3][4][5] energy that occurs when current-carrying contacts are opened and closed. An electric arc is a man-made, continuous arc-discharge consisting of highly energized electrons and ions supported by an electric current of at least 100mA; not to be confused with an ...
