Why Choose the ABB 1SDA060626R1 TA External Neutral 300A T5 UL?
The ABB 1SDA060626R1 is a 300 A external neutral current transformer designed for ABB SACE Tmax T5 circuit breaker applications. Identified by ABB as TA EXT NEUTRAL 300A T5 UL, this genuine ABB accessory provides external neutral-current measurement for compatible Tmax T5 protection arrangements.
As part of the ABB SACE Tmax T accessory range, the 1SDA060626R1 enables current in an external neutral conductor to be monitored where neutral-current information is required by the circuit breaker's electronic protection system. This makes it suitable for three-phase, four-wire distribution arrangements in which the neutral conductor is routed separately from the breaker poles.
Rated at 300 A and specifically designated for the ABB Tmax T5 platform, the 1SDA060626R1 is the UL-version external neutral transformer for compatible applications. Its dedicated ABB design supports coordinated integration with the appropriate Tmax T5 circuit breaker and electronic trip-unit configuration.

Reliable Neutral-Current Measurement for Tmax T5 Protection
An external neutral current transformer measures the current flowing through a neutral conductor located outside the circuit breaker's main current paths. In compatible electronic protection systems, this measurement allows the trip unit to account for neutral current when applying the required protection functions to a three-phase, four-wire electrical distribution system.
The ABB 1SDA060626R1 provides a dedicated 300 A external neutral sensing solution for the Tmax T5. Correct matching between the external neutral transformer, circuit breaker and electronic trip unit is important to ensure that the protection system receives the appropriate neutral-current measurement.
Typical Applications
- ABB SACE Tmax T5 circuit breaker installations.
- External neutral-current measurement.
- Three-phase, four-wire electrical distribution systems.
- Industrial low-voltage switchboards.
