Why Choose the ABB 1SDA066976R1 TA NEUTRO EXT 63A XT4 External Neutral Current Transformer?
The ABB 1SDA066976R1 is a 63 A external neutral current transformer for ABB SACE Tmax XT4 moulded-case circuit breakers. Identified by ABB as TA NEUTRO EXT 63A XT4, this genuine accessory is designed for applications requiring current measurement of an external neutral conductor.
ABB describes the device as CI 63 A FOR EXTERNAL NEUTRAL XT4. It forms part of the current-sensing accessories available for the Tmax XT4 platform and is used where the neutral conductor is external to the circuit breaker and its current must be monitored by the compatible protection system.
With a rated current of 63 A, the 1SDA066976R1 provides a purpose-designed ABB sensing solution for compatible XT4 installations. It is particularly suited to low-voltage distribution systems where accurate integration of the external neutral conductor into the circuit breaker's protection arrangement is required.

External Neutral Current Sensing for Tmax XT4
In electrical distribution systems where the neutral conductor is routed externally to the circuit breaker, an external neutral current transformer enables the compatible protection system to obtain the neutral-current measurement required for its protection functions. The transformer provides the sensing interface between the external neutral conductor and the circuit breaker's electronic protection arrangement.
The ABB 1SDA066976R1 is the 63 A external neutral current transformer for the Tmax XT4 platform. By using an accessory engineered specifically for the XT4 system, panel builders and electrical engineers can integrate external neutral current sensing into compatible ABB circuit-breaker installations.
Typical Applications
- Industrial low-voltage switchboards.
- Electrical power distribution panels.
- Systems using an external neutral conductor.
- Machine control and power distribution cabinets.
- OEM electrical equipment and switchgear assemblies.
- Compatible ABB SACE Tmax XT4 installations requiring 63 A external neutral current sensing.
