Selection Notes
Order this XT3 instantaneous release where earth-fault protection must trip without delay on larger four-pole Tmax XT3 breakers; the heavier 1.875 kg unit reflects the bigger XT3 frame it mounts on. Because it has no adjustable delay, pair it with dedicated downstream RCDs for selectivity rather than relying on this release alone.
