1SDA073736R1 ABB EXT CS N E1.2 – E2.2 2000A External Neutral Current Sensor

Why Choose the ABB EXT CS N E1.2 - E2.2 2000A External Neutral Current Sensor?

The ABB EXT CS N E1.2 - E2.2 2000A, order code 1SDA073736R1, is an external neutral current sensor designed for compatible ABB SACE Emax 2 air circuit breakers. Rated for 2000 A, it enables the electronic protection system to measure neutral-conductor current when the neutral is external to the circuit breaker.

Part of the ABB SACE Emax 2 accessory range, the external current sensor extends current measurement and protection functionality to the neutral conductor in suitable installations. It is intended for compatible E1.2 and E2.2 circuit-breaker configurations where neutral-current information is required by the Ekip electronic trip unit for system protection and monitoring.

With a 2000 A current rating, the 1SDA073736R1 provides a purpose-designed ABB solution for high-current low-voltage distribution systems. Its integration with the Emax 2 protection architecture helps provide coordinated current sensing across the phase and external neutral conductors.

External Neutral Current Measurement for Emax 2

In low-voltage distribution systems where the neutral conductor does not pass through the circuit breaker, an external neutral current sensor allows the electronic protection system to obtain the neutral-current measurement required for compatible protection and monitoring functions. This helps maintain coordinated sensing across the electrical installation.

The ABB 1SDA073736R1 is designed for compatible Emax 2 E1.2 and E2.2 applications with currents up to its 2000 A rating. By integrating with the circuit breaker's electronic protection architecture, it supports accurate supervision of the external neutral in demanding power distribution systems.

Typical Applications

• ABB SACE Emax 2 E1.2 and E2.2 circuit-breaker installations.
• External neutral current measurement.
• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical installations.
• Protection systems requiring neutral-current sensing.
