Was wondering if anyone has ever used the "point of use" (secondary type) Intermatic AG2401 model surge protector ?
If so, opinions on ?
It supposedly clamps at 490 V.
This seems to me awfully high, and possibly above what many solid state components and microprocessors would possibly be destroyed at.
Do you think it (still) would provide adequate protection and be worth installing ?
Any thoughts on this, or recommendations, perhaps, on similar units that clamp lower ?
BTW: when having worked within their limits, are typical MOV's usually good for many such clampings, or do they degrade quickly, even if the clampings were "nominal" ?
