I suspect the 60Hz is a typeo / misreading of the plates on the appliance.
It's more than likely 220V 50Hz Single phase
or 380V 50Hz 3-phase.
Just as a note:
Pre 1990s the UK, Malta and Cyprus used 240V (single phase) and 415V (Three phase)
The rest of the EU, including Ireland, used 220V (single phase) and 380V (three phase)
Most appliances were rated 220-240V / 380-415V
However, to make things simple, CENELEC, the European regulatory body that controls harmonisation of electrical codes and standards re-standardised to 230V and 400V. This is within the tollerance limits of both 220V and 240V appliances.
Hence, on more recent European appliances you'll see 230V or 400V for 3 phase.
An appliance rated 230V will also happily work on 220 or 240V etc..
It's a bit like the US 110V creeping to 120V
