Secondary Connections for Withdrawable XT2-XT4 Breakers
Withdrawable circuit-breaker installations can require dedicated secondary connections so auxiliary power, communication and protection-related signals remain correctly integrated with the breaker arrangement. The ABB 1SDA105206R1 groups the required auxiliary supply, internal bus, external neutral and selectivity connections into a coordinated kit for compatible withdrawable XT2 and XT4 breakers.
The selectivity connection supports applications using compatible selectivity functions, including ZSI-related signalling, while the external-neutral connection provides the required interface where the protection arrangement incorporates an external neutral. Using the dedicated ABB kit helps maintain compatibility with the intended SACE Tmax XT electrical accessory architecture.
Typical Applications
