The ABB 1SDA066977R1 is a 100 A external neutral current sensor for ABB SACE Tmax XT4 moulded-case circuit breakers. Identified by ABB as TA NEUTRO EXT 100A XT4, this genuine accessory is designed for applications requiring current sensing on an external neutral conductor.
ABB describes the device as TA 100 A PER NEUTRO ESTERNO XT4. It provides the neutral-current sensing interface required in compatible XT4 protection arrangements where the neutral conductor is external to the circuit breaker, including installations using appropriate ground-fault protection.
Rated at 100 A, the 1SDA066977R1 is purpose-designed for the Tmax XT4 platform. It provides panel builders, OEMs and electrical engineers with a genuine ABB sensing accessory for incorporating an external neutral conductor into compatible circuit-breaker protection systems.
Where a neutral conductor is external to a moulded-case circuit breaker, a dedicated neutral current sensor can be used to provide the compatible protection system with the required neutral-current measurement. This is particularly relevant to protection arrangements where the current in the neutral must be included in the circuit breaker's monitoring or ground-fault protection scheme.
The ABB 1SDA066977R1 provides a 100 A external neutral sensing solution for the Tmax XT4 platform. ABB documentation identifies this order code as the 100 A neutral sensor used with compatible XT4 installations, providing a purpose-designed interface for integrating the external neutral into the protection system.
