1SDA059635R1 ABB SACE New Emax E2N/E 12 1250 A 1150 V AC Special Version

Why Choose the ABB 1SDA059635R1 E2N/E 12 1150 V AC Special Version?

The ABB 1SDA059635R1 is a SACE New Emax E2N/E 12 special-version extra code designed to extend the corresponding E2N 12 circuit breaker configuration to applications operating at up to 1150 V AC. This specialised Emax /E solution is intended for higher-voltage low-voltage distribution systems where conventional 690 V AC equipment is not sufficient.

The E2N/E 12 designation corresponds to a 1250 A rated uninterrupted current and provides an ultimate short-circuit breaking capacity of 30 kA at 1150 V AC. ABB specifies the 1SDA059635R1 special-version code in addition to the appropriate standard E2N 12 circuit breaker configuration, allowing the final assembly to retain the pole, installation and protection characteristics selected for the associated base breaker.

The Emax /E platform is designed for specialised industrial power systems and offers a 1250 V AC rated insulation voltage and 12 kV rated impulse withstand voltage. These characteristics make the E2N/E 12 suitable for demanding installations such as mining, oil and gas, chemical processing, traction and other electrical networks requiring operation at 1150 V AC.

Specialised Circuit Protection for 1150 V AC Power Distribution

ABB's SACE Emax /E range extends circuit-breaker applications beyond conventional 690 V AC distribution networks to specialised systems operating at up to 1150 V AC. This makes the platform particularly useful for industrial installations where higher distribution voltages can reduce current requirements for a given power level while demanding equipment specifically designed and tested for the increased operating voltage.

The E2N/E 12 combines a 1250 A current rating with 30 kA short-circuit breaking capability at 1150 V AC. Because 1SDA059635R1 is an extra code used with the corresponding standard E2N 12 breaker, characteristics such as pole configuration, fixed or withdrawable construction and electronic protection functions depend on the selected base circuit breaker.

Typical Applications

• Mining electrical distribution systems.
• Oil and gas installations.
• Chemical and process plants.
• Traction and specialised transport power systems.
• Industrial networks operating above conventional 690 V AC distribution voltages.
• High-service-voltage main distribution switchboards.
• Specialised 1150 V AC low-voltage power distribution systems.
