1SDA059027R1 ABB E3H/E MS 2000 4P 1150V AC F HR Switch Disconnector

Why Choose the ABB E3H/E MS 2000 4P 1150V AC F HR Switch Disconnector?

The ABB E3H/E MS 2000 4P 1150V AC F HR, order code 1SDA059027R1, is a high-voltage SACE Emax air switch disconnector engineered for switching and isolation in demanding AC power distribution systems. Built on the ABB E3 frame, this four-pole device provides a rated uninterrupted current of 2000 A and a rated operational voltage of 1150 V AC.

This E3H/E MS configuration combines a fixed installation with rear flat horizontal terminals, providing a robust arrangement for integration into high-current switchboards and engineered busbar systems. Its H performance level and rated short-time withstand current of 30 kA for 1 s support reliable operation in installations requiring switching and isolation above conventional 690 V AC distribution levels.

The device has a rated insulation voltage of 1250 V and rated impulse withstand voltage of 12 kV. As a SACE Emax switch disconnector, it is intended for circuit switching and isolation rather than providing integral overcurrent protection, allowing it to be coordinated with separate protective devices within the electrical installation.

Key Advantages

• 2000 A rated uninterrupted current for high-capacity power distribution.
• Designed specifically for elevated-voltage operation at 1150 V AC.
• Four-pole construction provides simultaneous switching across four conductors.
• Fixed installation provides a robust permanent switchboard solution.
• Rear flat horizontal terminals support efficient integration with high-current busbar systems.
• 30 kA short-time withstand current for 1 s for demanding distribution applications.

Key Features

• ABB SACE Emax E3H/E MS series.
• 2000 A rated uninterrupted current.
• 1150 V AC rated operational voltage.
• Four-pole (4P) construction.
• Fixed (F) installation version.
• Rear flat horizontal (HR) terminal arrangement.
• 1250 V rated insulation voltage.
• 12 kV rated impulse withstand voltage.

• Suitable for use as a main switch in compatible installations.

Reliable 1150 V AC Switching and Isolation

The ABB E3H/E MS 2000 is engineered for installations that require dependable switching and isolation at operating voltages up to 1150 V AC. Its elevated 1250 V insulation rating, four-pole construction and fixed Emax architecture make it particularly suitable for specialised industrial power systems where conventional 690 V equipment does not provide the required voltage capability.

With a continuous-current rating of 2000 A, 30 kA one-second short-time withstand capability and rear horizontal busbar connection arrangement, the device provides a robust interface for high-capacity distribution systems. The SACE Emax platform also supports optional operating and release accessories, allowing the switch disconnector to be integrated into engineered control and isolation schemes.

Typical Applications

• High-voltage industrial AC distribution systems up to 1150 V AC.
• High-current main incoming isolation.
• Industrial low-voltage switchboards and power distribution assemblies.
• Four-pole feeder and busbar isolation.
• Heavy industrial plants and manufacturing facilities.
• Specialised high-power electrical installations requiring fixed switch disconnectors.
