Having referred to the standard, The keyway(s) have nothing to do with current rating. They relate to the temperature rating of the connector. 10A connectors are rectangular with two bevelled corners only for standard conditions. They have a single keyway on the longer side for 'hot' conditions, and have an additional key on the short side for 'very hot' conditions. 16A connectors are rectangular without the bevelled corners.
