1SDA060529R1 ABB XK3 Zone Selectivity Connection Kit for PR122/3 Emax E1-E6

Why Choose the ABB 1SDA060529R1 XK3 Zone Selectivity Connection Kit?

The ABB 1SDA060529R1, manufacturer designation KIT XK3 CONN. ZONE SEL PR122-3 E1-6, is a zone selectivity connection kit designed for compatible ABB SACE Emax air circuit breakers equipped with PR122 or PR123 electronic trip units. As part of the ABB SACE Emax accessory range, the kit provides the XK3 connection interface required for zone selectivity signalling within coordinated low-voltage protection systems.

Zone selectivity is used to improve protection coordination between circuit breakers at different levels of an electrical distribution system. By exchanging selectivity signals between compatible protection releases, the system can identify the protective device closest to a fault and minimise unnecessary operation of upstream breakers, helping improve continuity of supply.

The 1SDA060529R1 is intended for compatible ABB SACE Emax E1–E6 circuit breakers using PR122 or PR123 electronic protection releases. Its XK3 connection functionality makes it a dedicated accessory for implementing the wiring and signalling required by supported zone-selective interlocking applications.

Zone Selectivity for Coordinated Circuit Protection

Zone selectivity, also known as zone-selective interlocking, allows compatible electronic protection devices to exchange information when an overcurrent or short-circuit condition occurs. This communication helps the protection system determine which circuit breaker is closest to the fault so that the appropriate device can operate while upstream protection can remain closed where system conditions permit.

The ABB XK3 connection kit provides the connection interface required for supported zone-selectivity functions on compatible SACE Emax circuit breakers equipped with PR122/3 or PR123/3 protection releases. This makes it particularly useful in distribution systems where selective fault isolation and reduced disruption to unaffected circuits are important design objectives.
