1SDA058551R1 ABB SACE Emax E6H/E 50 5000 A 1150 V AC Special Version

Why Choose the ABB 1SDA058551R1 Emax E6H/E 50 1150 V AC Special Version?

The ABB 1SDA058551R1 is a special 1150 V AC version for the SACE Emax E6H/E 50 air circuit breaker, designed for demanding high-current AC power distribution applications. Identified by ABB as E6H/E50VERS.SPEC.1150VACnew(EXTR), this extra-code configuration provides an E6H/E 5000 solution specifically rated for operation at 1150 V AC.

The E6H/E 50 platform provides a 5000 A rated uninterrupted current and is designed for high-capacity industrial electrical distribution. Its H short-circuit performance level, 1250 V insulation rating and substantial short-time withstand capability make it suitable for specialised installations where conventional 690 V AC circuit-breaker configurations are insufficient.

With a 1150 V AC rated operational voltage, 1250 V rated insulation voltage and 12 kV rated impulse withstand voltage, the 1SDA058551R1 supports demanding electrical environments. The E6H/E 50 configuration also provides a 65 kA short-time withstand current for 1 s, combining high current capacity with robust electrical withstand performance.

High-Current Protection for 1150 V AC Power Distribution

ABB SACE Emax air circuit breakers are designed for switching and protection in high-current electrical distribution systems. The E6H/E special execution extends the application range to 1150 V AC, enabling Emax technology to be used in specialised industrial systems operating above the conventional 690 V AC range.

The E6H/E 50 combines a 5000 A current rating with high insulation and short-time withstand characteristics. Its 65 kA for 1 s short-time withstand rating supports selective protection strategies in high-power distribution networks, while the 1250 V insulation voltage and 12 kV impulse withstand rating provide the electrical withstand performance required for its elevated operating voltage.
