I have an APC Performance SurgeArrest 12 that is rated at 330.
Also rated at 330, a Monoprice 12 Outlet Power Surge Protector.
They both said so in the description and the manual.

If they are lying it will be hard to know the rating.

I think that UL1449 (Surge Protective Devices) have been using Voltage Protection Rating, and clamping voltage was drop since version 3.
