Several options to be considered: • 1. The easiest is using hager single module RCBOs. These are electronic devices, type AC, 6kA, 10-32A. • 2. Mount a 2 pole or 4 pole RCCB either top left or top right on the provided DIN rail sections. • 3. Use earth leakage relays mounted on DIN rail, with the supply passing through the earth leakage toroid. The trip contacts of the earth leakage relay should be wired to the shunt trip of the supplying MCCB.
