(1) An assembly language instruction that copies data from one location to another. See move and machine instruction.

(2) (MOVie) A QuickTime video file extension. See QuickTime.

(3) (Metal Oxide Varistor) A discrete electronic component that is commonly used to divert excess voltage to the ground and/or neutral lines. Acting like a pressure relief value, an MOV is made of zinc oxide with small quantities of bismuth, cobalt, manganese and other metal oxides. The MOV was introduced in Japan in the late 1960s and was also developed by GE in the 1970s.

One of the major problems with MOVs is that the more they receive surges, the more they wear out, and there is no warning that the components are failing. See surge suppression.

The centerpiece of the building is the Hall of Valor, featuring the framed photos of PMA MOV awardees, with their respective citations.
This stress may not be enough to cause the MOV to fail, but will result in degraded operation with the clamping voltage rising higher and higher until it will no longer conduct current in an overload.
In the event of an over-voltage condition, the MOV or MLV device switches rapidly from a high to a low impedance state, thus clamping the transient voltage across the components to a safe operating level.
Some MOV based suppressor products boast very high surge current capacities of up to 300,000 Amperes without reporting the voltage protection level.
While parallel MOV TVSS products are designed to withstand high-energy strikes, manufacturing tolerance of the MOV makes it difficult to ensure the parallel components operate simultaneously to share the transient energy.
