What are the trip times for a 30mA RCCB?

Several standards define these times (AS/NZS 61008.1:2004 and AS/NZS 61009.1:2004). At 30mA the trip time must be less than 300ms. Increase the residual tripping current and the tripping time decreases, eg at a residual tripping current of 150mA (5 x IΔn) the RCCB or RCBO must trip in under 40ms.
