For 4P, 300mA cheap ma coz insensitive.
They sell the 300mA because still valid use for industry.
Not all RCD created equal
Should use the 30mA then up to par with current residential standard. 4P 30mA 63A usually cost almost double of the 4P 300ma.
Personally I'd still try to swap out to 30mA, safety first.
