Selective differential circuit breakers with built-in overcurrent protection are used to construct selective (multi-stage) differential current protection schemes.
Designed for operation in single-phase AC electrical circuits with a voltage of 230 V and a frequency of 50 Hz, rated for nominal current from 20 A to 63 A. The rated residual current (trip setting) is 100 mA and 300 mA.
Used in distribution boards of residential and public buildings, apartment panels, temporary power supply devices for construction sites, garden houses, and garages. Thanks to the advanced design of the differential unit and compact dimensions, space saving in the panel is ensured.
