Good afternoon all,

I have two 3phase 15.75kW ducted units servicing my home. About 25 year old custom designed units and working absolutely perfectly. I was just thinking would it be any benefit to the system to install a 3 phase soft starter to each unit. Would that protect the compressor at start up or is it mainly just to protect from the higher startup current and costs?

I dont have any intention to replace the units, they are specifically designed and fitted under the home and would replace components as and if required, so am rather looking for a way of maintaining or promoting longer life within the components and any future ones.
