Rated residual current and trip time limits for RCDs
The RCD selection tool reads the maximum rated residual current and the two trip time limits for the protection duty of the device. A measured trip time is compared with those limits.
Verified: read against the printed standard, pages 36–37. Checked 26 Sept 2026.
Units: Max rated ma mA, Trip at rated ms ms, Trip at five ms ms, No trip at fraction x
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
