It would probably offer you some protection but it wouldn't be doing quite what it was designed to do. If the leg you were on made excursions close to 240VAC because of a heavily loaded opposite leg, the MOV H-N in the suppressor might start clamping the sine wave. The MOVs would be dissipating energy for repetitve mS instead of infrequent uS or nS, as they are designed for. It would be a race between the MOV to blow or the overcurrent protection to trip. If the the MOVs clamp higher than 240VRMS, the suppressor would be of no use. Joe

If your computer power supply is a wide range input type, typically 90 to 240 volts, then it should survive. Most recent ones here in europe are this type, especially as they now must have power factor correction built in.

Funny, my experience says "yes." I once made a poor neutral connection, and during the night fried a stereo power supply, a couple ballasts, two UPS units, and several surge suppressors; the computers that had the power strips before the UPS (or computer) came through undamaged.

Many years ago one of the computer trade rags did a story on this. Thier conclusion was a good strip would protect you if the on strip O/C device opened up with the MOV overload. A lot still depends on the threshold and current capability of the MOV.
