- Description
The RC Sel HV 85...690Vac XT3 3p F release, ABB 1SDA067128R1, brings selective residual current protection to fixed three-pole Tmax XT3 circuit breakers over the 85-690 V AC range. Its built-in delay stage lets it coordinate with downstream residual current devices instead of tripping on every fault instantaneously. EAN 8015644010355, weight 1.447 kg.

Selection Notes
Choose this three-pole release for larger Tmax XT3 breakers on three-wire circuits needing selective, not instantaneous, earth-fault protection; at 1.447 kg it is heavier than the equivalent XT1 release to suit the bigger XT3 body. The delay stage lets it sit upstream of faster residual current devices without nuisance tripping.
