Low voltage selectivity with ABB circuit-breakers

A complete paper about selectivity, including theory and basic techniques, with specific indications on the implementation of selectivity between ABB low voltage circuit-breakers.

Code: 1SDC007100G0205

Directional protection and directional zone selectivity

A comprehensive description of the application area and the use of «D» directional protection and «SdZ» directional zone selectivity functions, with application references and examples.

Code: 1SDC007401G0201

Integration between the MV protection and control unit REF542 and the LV protection trip unit with PR123: selectivity and earth fault

A theoretical analysis of the possibilities of integration between ABB medium and low voltage protection trip units (in particular, MV REF542 and LV PR123), and an «how to make» section, with a description of the way to realize appropriate coordination and cabling with ABB devices.

Code: 1SDC007402G0201

PR223EF
Zone selectivity with Early Fault Detection and Prevention technology

Detailed information about the proper use and correct configuration of the PR223EF trip unit to obtain the maximum advantages in installations requiring zone selectivity.

Besides making available Zone Selectivity Interlocking (ZSI) for MCCBs, the PR223EF trip unit introduces a selectivity concept called Early Fault Detection and Prevention (EFDP). If logical selectivity operates in the range 1…10xIn, EFDP selectivity is usually active approximately in the range from 10xIn and the Icu of the circuit breaker.
