Had a nosey at a couple of the Square D RCBOs, the older one (QOE) has the symbol on for type A whereas the newer one (KQ) only has the AC symbol. The old one has the green/yellow stripe earth wire whereas the new one has a cream functional earth wire. The old one has both BSEN 60898 and BS 4293 printed on the side as opposed to the newer BSEN 61009.
