Reading the rest of that paragraph, they don't say what their Tri-Mode™ circuitry does except "disconnects your equipment".
Umm... MOVs are sacrificial, that is, if you get a direct lightning strike to your breaker panel and it travels to the surge protector, chances are the $15 surge protector will be toast, the MOVs will do their job... high voltage comes in, they go into low resistance mode, shunt the power out to ground, chances are they may not survive the process and assuming it doesn't melt your mains wiring or the power bar itself... yes, if the MOVs burn out on strike #1, and you get hit again, they won't be around to save your equipment the second time (you'll notice on good ($20) surge protectors, over time the red light begins to blink... it's an indicator of the life left in the MOVs).
But if you get hit twice in a row like that... throw your hands up, become an agnostic and call the insurance company.
Again, to the moonlighting job - we've got Sony A75 & 1800 VTRs w/DNR RS-422 ST-300 controller, a Ross RVS210A switcher, a Pinnacle Deko 500, a Drastic VVW DDR with an RS-422 controller, banks of Frame-Stors, etc. The computer-based equipment is backed up by APC UPSes for the sag before the diesel genny kicks in, the rest get power through consumer surge protectors.
