Abstract
An enhanced surge protection device (SPD) includes a stacked SPD subassembly having a plurality of metal oxide varistor (MOV) layers, a return conductor plate and a negative conductor plate disposed at opposing outer sides of the MOV layers, and at least one ground plate disposed within the MOV layers. A return terminal is electrically coupled to the return conductor plate, a negative terminal electrically is coupled to the negative conductor plate, and a ground terminal is electrically coupled to the ground plate.
Claims20
A stacked surge protection device (SPD) subassembly, comprising:
- a stacked assembly including a plurality of metal oxide varistor (MOV) layers including at least a first MOV layer and a second MOV layer;
- a return conductor plate disposed at a first outer side of the stacked assembly;
- a negative conductor plate disposed at a second outer side of the stacked assembly opposite the first outer side;
- at least one ground plate disposed within the stacked assembly between the return conductor plate and the negative conductor plate;
- and
- a return terminal electrically coupled to the return conductor plate, a negative terminal electrically coupled to the negative conductor plate, and a ground terminal electrically coupled to the at least one ground plate.
A surge protection device (SPD), comprising:
- a stacked SPD subassembly including a stacked assembly having a plurality of MOV layers, a return conductor plate and a negative conductor plate disposed at opposing outer sides of the stacked assembly, and at least one ground plate disposed within the stacked assembly;
- a return electrical interface electrically coupled to the return conductor plate, a negative electrical interface electrically coupled to the negative conductor plate, and a ground electrical interface electrically coupled to the at least one ground plate;
- an integration structure configured to incorporate the stacked SPD subassembly into a power distribution path;
- and
- a contactor assembly including (i) a fixed contact, (ii) a movable contact, and(iii) a spring biasing the movable contact relative to the fixed contact, the contactor assembly being configured to change an electrical continuity state between the fixed contact and the movable contact in response to a failure condition associated with at least one MOV layer of the stacked SPD subassembly.
