Why Choose the ABB E3 External Neutral Current Sensor?
The ABB E3 External Neutral Current Sensor, order code 1SDA058218R1, is an accessory for the ABB SACE Emax E3 air circuit breaker platform. Identified by ABB as CURR.S.EXT.NEUTRAL N50-100%E3 N50%E, it is intended for external neutral current sensing in compatible E3 circuit-breaker installations.
External neutral current sensing is used where the neutral conductor needs to be monitored separately from the breaker poles. This accessory provides the sensing element required for compatible protection arrangements, allowing the circuit breaker's electronic protection system to account for neutral current in the electrical distribution system.
The 1SDA058218R1 is specifically associated with the E3 frame and is identified with N50-100% and N50% neutral-current sensing designations. Selecting the correct ABB accessory for the breaker frame and protection configuration helps maintain proper integration within SACE Emax switchgear.

External Neutral Current Sensing for SACE Emax Protection
In power distribution systems where the neutral conductor is not incorporated as a breaker pole, an external neutral current sensor can provide the current information required by a compatible electronic protection arrangement. This enables the protection system to include neutral-conductor current when monitoring the electrical installation.
The ABB 1SDA058218R1 is intended for the SACE Emax E3 platform and should be matched to the applicable breaker, trip unit and neutral-protection configuration. Its dedicated E3 compatibility makes it suitable for switchboard construction, maintenance and replacement applications requiring the specified external neutral sensing arrangement.
Typical Applications
- ABB SACE Emax E3 switchgear assemblies.
- External neutral current measurement.
- Neutral-conductor monitoring in compatible protection systems.
- Industrial low-voltage power distribution boards.
- Switchboard construction and retrofit projects.
- Replacement of compatible E3 external neutral sensing accessories.
