Ranco etc burned out?

[westom]

Will this one do the job? Its the highest quality one i can find. I just dont want a repeat of what happened with the ranco cause if i didnt catch it sooner it wouldve been a big problem for my animals, so i want the best of the best protection!

Tripplite does nothing for what would have caused a previous failure. Protectors are for a transient that can occur maybe once every seven years. It would be incoming to all appliances. If a thermostat needs one, then protection is essential for a dishwasher, bathroom GFCIs, all clocks, LED bulbs, TV, central air conditioner, computer, refrigerator, recharging phone, and (the most critical appliance when a surge exists) all smoke detectors.

Your failure is typical of a most common reason for electronics failure - manufacturing defects. Internal inspection could say more. Others noted this manufacturer's high failure rate. Same would explain your failure. Identifying a failed part would say why failure happened. Most electronics failures are due to manufacturing defects - not surges.

Install one 'whole house' protector for about $1 per protected appliance - so that everything (including a 'tiny joules' Tripplite and a thermostat) is protected from a transient that can occur once every seven years. Then thousands of joules do not even create a protector fire. Then a potentially destructive transient does not overwhelm superior protection already inside every appliance (including a thermostat). Even a Tripplite needs that protection.
