Why Choose the ABB 1SDA066978R1 External Neutral Current Transformer?
The ABB 1SDA066978R1 is a genuine 160 A external neutral current transformer designed for use with compatible ABB SACE Tmax XT4 moulded-case circuit breakers. Identified by ABB as TA NEUTRO EXT 160A XT4, this accessory provides current measurement on an external neutral conductor as part of a compatible low-voltage protection system.
As part of the ABB Tmax XT accessory range, the 1SDA066978R1 is engineered specifically for integration with the XT4 circuit breaker platform. An external neutral current transformer allows the protection system to monitor neutral current when the neutral conductor is external to the circuit breaker, supporting appropriate protection and current sensing in suitable electrical distribution configurations.
With a rated current of 160 A, the 1SDA066978R1 provides a purpose-designed ABB solution for compatible XT4 installations. Its dedicated design makes it suitable for switchboards, distribution panels and industrial electrical systems where external neutral current measurement is required.

External Neutral Current Measurement for ABB Tmax XT
In electrical distribution systems where the neutral conductor is external to the circuit breaker, a dedicated current transformer can provide the protection system with the neutral-current measurement required for compatible protection functions. This allows the circuit breaker and associated electronic protection equipment to account for current flowing through the external neutral conductor.
The ABB 1SDA066978R1 is specifically rated at 160 A and designed for the Tmax XT4 platform. Using a purpose-designed ABB accessory helps maintain compatibility between the current sensing component and the associated circuit breaker protection system, making it suitable for professionally engineered low-voltage switchboards and distribution assemblies.
Typical Applications
- ABB SACE Tmax XT4 moulded-case circuit breaker installations.
- External neutral conductor current measurement.
- Low-voltage electrical distribution systems.
- Industrial switchboards and switchgear assemblies.
- Commercial power distribution panels.
- Electrical protection systems requiring external neutral current sensing.
