For inverter fridges, a fridge guard or voltage protector with a 13A, 220V–240V rating is the practical baseline, and many units sold for fridges/freezers are listed around that range. If you want broader protection for surges and unstable supply, the more important spec is not just amperage but the clamping/let-through voltage; lower is better, and around 400V or below is commonly recommended in the source material I reviewed.
What rating to look for
For a typical household inverter fridge on Kenya’s 230V supply, choose a protector rated for 220V–240V and at least 13A so it can handle the fridge’s normal current draw. If the protector is part of an AVR-style setup, capacity should comfortably exceed the fridge’s running load, since compressors draw more at startup.
Better protection spec
A fridge protector should also have a delay/restart function, because that helps protect the compressor after power returns. If the product lists a clamping voltage, aim for 400V or lower. That said, a small plug-in protector is not the same as whole-home surge protection, so it is only one layer of defense.
Practical choice
For an inverter fridge, the safest simple choice is:
-
13A rating
-
220V–240V compatibility
-
Delay-on-return feature
-
Low clamping voltage if specified
If the area has frequent voltage swings, pairing the fridge protector with proper earthing and, where appropriate, whole-house surge protection gives stronger protection than relying on a single plug-in device.
