How many joules does that protector claim to absorb?  Typically destructive surges are hundreds of thousands of joules.  How many joules in that protector's specs?

  That type protector is for people who want the phrase 'surge protection'.  And do not really ask for effective protection.  To few consumers want a 240 volt version.

  A useful recommendation will say where hundreds of thousands of joules harmlessly dissipate.  Only solution used in any facility that cannot have damage is an earthed 'whole house' protector - not that Tripplite.  An effective protector connects low impedance (ie 'less than 10 feet') to earth.  Is connected to all incoming AC lines (does both 120 and 240 volt protection), and protects all appliances.

  More responsible companies provide these superior (and less expensive) solutions including Siemens, Syscom, General Electric, Intermatic, Polyphaser, ABB, Square D, Ditek, and Leviton to name but a few.  Companies well known for quality and integrity.  A Cutler-Hammer solution is available even in Lowes and Home Depot.

  No protector does protection.  Effective protectors are defined by what absorbs hundreds of thosands of joules.  To make that low impedance (ie 'less than 10 foot') connection to earth, these superior products are located in a main breaker box or on meter pan.  Even AC utilities can install one behind their meter.  Located here because that connection and distance to earth is critically important for effective protection - for all 120 and 240 volt appliances.

  'Whole house' protector is always implemented in every facility that cannot have damage.
