1SDA059634R1 ABB SACE New Emax E2B/E MS 20 2000 A 1150 V AC Special Version

Why Choose the ABB 1SDA059634R1 E2B/E MS 20 1150 V AC Special Version?

The ABB 1SDA059634R1 is a SACE New Emax E2B/E MS 20 special-version component for switch-disconnector applications operating at rated service voltages up to 1150 V AC. It forms part of ABB's Emax /E range developed for higher-voltage low-voltage distribution applications such as mining, oil and chemical plants, traction systems and specialised industrial installations.

This order code identifies the E2B/E MS 20 1150 V AC special version. ABB specifies this code for use together with the appropriate standard-version Emax switch-disconnector configuration, rather than as a complete standalone breaker specification. The E2B/E MS platform supports both three-pole and four-pole arrangements and fixed or withdrawable installation according to the associated base device.

For the E2B/E MS range, ABB specifies a 1150 V AC rated operational voltage, 1250 V AC rated insulation voltage, 12 kV rated impulse withstand voltage and 20 kA rated short-time withstand current for 1 s. The MS 20 designation corresponds to the 2000 A E2B/E switch-disconnector configuration.

Key Advantages

• Special ABB SACE New Emax /E version for applications up to 1150 V AC.
• E2B/E MS 20 configuration for high-voltage AC switch-disconnector applications.

Specialised Switching for 1150 V AC Power Distribution

ABB's SACE Emax /E range was developed for industrial installations requiring service voltages above those of conventional 690 V AC distribution systems. The special Emax /E platform extends the application range to 1150 V AC while retaining the installation flexibility and accessory concept of the corresponding SACE New Emax family.

The E2B/E MS switch-disconnector platform is intended for switching and isolation rather than incorporating an electronic overcurrent trip unit. ABB specifies the E2B/E MS 20 with a 20 kA short-time withstand current for 1 s, making the special version suitable for high-service-voltage distribution systems where dependable isolation and fault-current withstand capability are required.

Typical Applications

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