Why Choose the ABB EXT CS N XT4 Ekip Touch IEC 1SDA105151R1 Current Sensor?
The ABB 1SDA105151R1 is an external neutral current sensor designed for ABB SACE Tmax XT4 circuit breakers equipped with a compatible Ekip Touch trip unit. Part of the ABB Tmax XT accessory range, it enables the protection system to monitor current flowing through an external neutral conductor.
In installations where the neutral conductor is external to the circuit breaker, the EXT CS N provides the Ekip Touch trip unit with the neutral-current measurement required for compatible protection and monitoring functions. Its dedicated design ensures integration with the XT4 platform without requiring the neutral conductor to pass through the breaker's integral phase-current sensing arrangement.
The 1SDA105151R1 is specified for IEC applications and provides a purpose-designed ABB solution for external neutral sensing in compatible low-voltage distribution systems. It is particularly suited to switchboards and distribution assemblies where accurate monitoring of the neutral conductor is required alongside the phase conductors.

External Neutral Current Measurement for Ekip Touch
An external neutral current sensor allows a compatible electronic trip unit to measure current flowing through a neutral conductor that does not pass through the circuit breaker's integral current sensors. This provides the trip unit with neutral-current information for supported measurement and protection functions within the electrical installation.
The ABB EXT CS N XT4 is specifically designed for integration with compatible SACE Tmax XT4 Ekip Touch configurations. By providing a dedicated interface for external neutral sensing, it supports coordinated current monitoring in low-voltage systems where the installation arrangement requires the neutral conductor to be monitored separately.
Typical Applications
- ABB SACE Tmax XT4 circuit-breaker installations.
- XT4 circuit breakers equipped with compatible Ekip Touch trip units.
- External neutral conductor current measurement.
- Industrial low-voltage electrical switchboards.
- Commercial power distribution panels.
- Electrical systems requiring compatible neutral-current monitoring and protection.
