Why Choose the ABB External Neutral Current Sensor N50-100% E1-E2?
The ABB external neutral current sensor, order code 1SDA058191R1, is an accessory for compatible ABB SACE Emax E1 and E2 air circuit breakers. Identified by ABB as CURR.S.EX.NEUTRAL N50-100% E1-2 N50%, it is designed to provide external neutral-current measurement where the neutral conductor is not switched directly through the circuit breaker.
The sensor enables the compatible Emax electronic protection system to monitor neutral current as part of the overall current-measurement arrangement. This is particularly useful in three-phase four-wire distribution systems where neutral-current information is required for the configured protection scheme.
This version is intended for E1-E2 applications and is identified with an N50% neutral-current configuration. As a dedicated SACE Emax accessory, it supports correct integration with the appropriate breaker and electronic trip-unit arrangement.

Neutral Current Measurement for SACE Emax Protection Systems
In a three-phase four-wire electrical system, the neutral conductor can carry current resulting from load imbalance and other operating conditions. An external neutral current sensor allows the circuit breaker's compatible electronic protection system to obtain neutral-current information even when the neutral conductor does not pass through a switched breaker pole.
The ABB 1SDA058191R1 is specifically intended for compatible E1 and E2 SACE Emax configurations. Correct sensor selection and integration are important because the neutral-current sensing arrangement must correspond with the breaker, trip unit and protection configuration used in the switchboard.
Typical Applications
- ABB SACE Emax E1 and E2 air circuit breaker installations.
- External neutral-current measurement.
- Three-phase four-wire low-voltage distribution systems.
- Main incoming and feeder protection assemblies.
- Industrial and commercial switchboards.
- Maintenance and replacement of compatible Emax current-sensing accessories.
