What means inrush in Electrical S4 Led series 2 datasheet?
Almost all electronics have some components (eg capacitors) that get "charged up" when the device is first powered up.
This means they draw a short 'burst' of current when they are first plugged in or powered on by a relay. This is the "inrush" current.
It matters because relays, switches, plugs/sockets and circuit breakers etc may all have a limit to the highest inrush current they can handle, as well as the maximum 'running' current.
In some cases you will not be able to add another fixture to a circuit because it will go over the maximum 'inrush' current, even though it will not reach the maximum 'running' current (max. power)
