Why Choose the ABB EXT CT N XT5 630 A Ekip Dip External Neutral Current Transformer?
The ABB 1SDA105156R1, designated EXT CT N XT5 630 A EKIP DIP IEC, is a 630 A current transformer for an external neutral conductor designed for ABB SACE Tmax XT5 moulded-case circuit breakers equipped with a compatible Ekip Dip electronic trip unit. It enables the trip unit to monitor current flowing through an external neutral conductor in applicable three-pole circuit-breaker installations.
External neutral current measurement is used where the neutral conductor is not routed through the circuit breaker but must still be included in the protection system. ABB specifies the external neutral sensor arrangement as enabling ground-fault protection with applicable three-pole circuit breakers, extending the Ekip protection system to the separately routed neutral conductor.
The 1SDA105156R1 has a 630 A rated current, is designed specifically for the SACE Tmax XT5 with Ekip Dip and is specified to IEC 60947-2. The accessory has an EAN / GTIN of 8015644072483 and a product net weight of approximately 0.1 kg.

External Neutral Measurement for Ekip Protection
In a three-pole circuit-breaker installation, the neutral conductor may run externally rather than through the breaker itself. An external neutral current transformer measures the current in this conductor and provides the required current information to the compatible electronic protection system.
The ABB 1SDA105156R1 is specifically rated at 630 A for compatible SACE Tmax XT5 Ekip Dip applications. By monitoring the external neutral, it enables the neutral conductor to be incorporated into applicable protection functions, including ground-fault protection arrangements specified for the circuit-breaker system.
Typical Applications
- ABB SACE Tmax XT5 circuit breakers with compatible Ekip Dip trip units.
- Three-pole circuit-breaker systems with an external neutral conductor.
- Industrial low-voltage switchboards.
- Power-distribution and feeder protection systems.
- Commercial and industrial electrical distribution panels.
- Applications requiring external neutral current measurement for applicable ground-fault protection.
