Displayed results:
x1 ........Step 1 trip-out time ( IΔN, 0º),
x1 ........Step 2 trip-out time (IΔN, 180º),
x2 ........Step 3 trip-out time (2×IΔN, 0º),
x2 ........Step 4 trip-out time (2×IΔN, 180º),
x5 ........Step 5 trip-out time (5×IΔN, 0º),
x5 ........Step 6 trip-out time (5×IΔN, 180º),
x½ .......Step 7 trip-out time (½×IΔN, 0º),
x½ .......Step 8 trip-out time (½×IΔN, 180º),
I .........Step 9 trip-out current (0º),
I .........Step10 trip-out current (180º),
Uc........Contact voltage for rated IΔN.
Notes:
 The autotest sequence is immediately stopped if any incorrect condition is
detected, e.g. excessive Uc or trip-out time out of bounds.
 Auto test is finished without x5 tests in case of testing the RCD type A with rated
residual currents of IΔn = 300 mA, 500 mA, and 1000 mA. In this case auto test
result passes if all other results pass, and indications for x5 are omitted.
 Tests for sensitivity (I
Δ
, steps 9 and 10) are omitted for selective type RCD.
