Anyone an idea why an RCBO measures >40ms on a 5x test on the second half of the sine wave but all other tests are within requirements? Sorry, it's not a single RCBO, there's 2 RCBOs in this board and both have similar results leading me to think not a faulty RCBO but an issue further upstream somewhere. Continuity, IR, Zs all textbook.
Trip times are something like 48ms on 1x, 28ms 5x on first half and >40ms second half 5 for both devices. No other RCBOs in the board but a different, adjacent board's RCBO tests fine.
