Hey Joe, thanks for reaching out. The Replacement Surge Protection Module # HU57ZR may work, but it depends on which 30-amp Power Watchdog you have.
If your Watchdog is 4–5 years old, there's a good chance it's a first-generation unit, not the newer Gen 2 WiFi model. In that case, the # HU57ZR is not the correct replacement. The # HU57ZR is only designed for second-generation 30-amp WiFi Watchdog surge protectors and 30-amp Watchdog Power Centers. It is not compatible with Gen 1 units.
If you can tell me the model number from the label on your Watchdog (for example, PWD30, PWD30-EPO, PWD30W, or PWD30EPOW), I can tell you the exact replacement module you need. The model number is usually printed on the side or back of the unit.
