Why Choose the ABB 1SDA055056R1 TA External Neutral 320A T5?
The ABB 1SDA055056R1 is a genuine 320 A external neutral current transformer designed for compatible ABB SACE Tmax T5 circuit breaker applications. Identified by ABB as TA EXT NEUTRAL 320A T5, it provides the external neutral current measurement required in suitable Tmax T5 protection configurations.
In installations where the neutral conductor is external to the circuit breaker's main poles, an external neutral current transformer allows the compatible protection system to monitor neutral current. The 1SDA055056R1 is rated at 320 A and is specifically associated with the ABB SACE Tmax T5 platform.
As an original ABB accessory, the 1SDA055056R1 provides a purpose-designed interface for compatible Tmax T5 protection arrangements rather than relying on a generic current transformer. It is suitable for low-voltage distribution systems, industrial switchboards and OEM assemblies requiring external neutral current sensing with a 320 A T5 configuration.

External Neutral Current Sensing for Tmax T5
An external neutral current transformer is used where a compatible circuit breaker protection arrangement needs information about current flowing through a neutral conductor that is not directly measured through the breaker's main current-sensing poles. The transformer supplies the neutral-current measurement required by the compatible protection configuration.
The ABB 1SDA055056R1 is specifically rated at 320 A for external neutral applications with the Tmax T5 platform. Correct matching of the external neutral transformer, circuit breaker and associated protection release is important, so the complete ABB configuration should be checked when specifying components for a particular installation.
Typical Applications
- ABB SACE Tmax T5 circuit breaker installations requiring external neutral sensing.
- Low-voltage power distribution switchboards.
- Industrial electrical distribution systems.
- Neutral-current measurement in compatible protection configurations.
- Main and sub-distribution panels.
- OEM switchgear using compatible ABB Tmax T5 protection systems.
