The R15 series comprises circular connectors with a screw locking
system.
The contact inserts with 8 cavities (7 + Ground) can be fitted with
crimp contacts for wire gauges from 0.14mm² to 2.5mm². The connectors
are rated at 10 A and 250 V (600 V according to UL and CSA). Plastic or
metal housings are available for this series.

Hi there - had a look at Harting and saw this, but what does this mean
600 V according to UL and CSA - is this just in the USA or something?

UL is only valid for the USA and CSA in Canada.

There's more to it than this too. The contacts really should to be 'finger
proof' acc to IEC 60065 for domestic use.
