1SDA073413R1 ABB E2.2H/MS 2000 3p F HR Switch Disconnector

Why Choose the ABB E2.2H/MS 2000 3p F HR Switch Disconnector?

The ABB E2.2H/MS 2000 3p F HR, order code 1SDA073413R1, is a high-performance SACE Emax 2 switch disconnector designed for reliable switching and isolation in high-current low-voltage electrical distribution systems. Built on ABB's E2.2 platform, this fixed three-pole device provides a 2000 A rated uninterrupted current and is suitable for industrial, commercial and infrastructure switchboards where robust isolation is required without an integral overcurrent protection trip unit.

The E2.2H/MS configuration is derived from the Emax 2 air circuit breaker platform but operates as a switch disconnector, providing switching and isolation while circuit protection is handled separately within the installation. Its fixed construction and horizontal rear terminals make it particularly suitable for switchboard designs requiring rear busbar or cable connections.

Rated for operation at up to 690 V AC, the E2.2H/MS 2000 provides a rated short-time withstand current of 85 kA for 1 s and 66 kA for 3 s. It is rated for AC-23A switching duty and combines high current-carrying capability with the mechanical platform and accessory flexibility of the ABB SACE Emax 2 range.

Key Advantages

• High 2000 A rated uninterrupted current for demanding low-voltage distribution systems.
• Three-pole switch disconnector for three-phase switching and isolation applications.

High-Performance Switching and Isolation for Power Distribution

Switch disconnectors provide a reliable means of making, carrying and isolating electrical circuits while overcurrent and short-circuit protection is provided separately. Devices based on air circuit breaker platforms are particularly useful in high-current switchboards because they combine robust switching mechanisms with high short-time withstand capability and flexible installation options.

The ABB E2.2H/MS 2000 combines a 2000 A continuous-current rating with an 85 kA short-time withstand rating for 1 s. Its fixed three-pole construction and horizontal rear terminals make it well suited to main isolation, busbar switching and high-current feeder applications where dependable isolation and efficient switchboard integration are priorities.

Typical Applications

• Main switchboard switching and isolation.
• Industrial low-voltage power distribution systems.
• High-current feeder switching and isolation.
• Busbar and bus-section isolation.
• Manufacturing and process plant switchboards.
• Commercial buildings and critical infrastructure.
