1SDA073495R1 ABB E2.2B/MS 2000 3p WMP Switch Disconnector

Why Choose the ABB E2.2B/MS 2000 3p WMP Switch Disconnector?

The ABB E2.2B/MS 2000 3p WMP, order code 1SDA073495R1, is a high-current three-pole withdrawable air switch disconnector from the ABB SACE Emax 2 range, designed for dependable switching and electrical isolation in low-voltage power distribution systems. Built on the E2.2 frame, this /MS device provides a substantial 2000 A rated uninterrupted current for industrial, commercial and infrastructure switchboards.

The E2.2B/MS combines its high continuous-current capacity with a rated short-time withstand current of 42 kA for 1 s. This enables the switch disconnector to withstand demanding fault-current conditions while appropriately coordinated protective equipment within the electrical installation provides automatic overload and short-circuit protection.

This model is supplied as the withdrawable moving part (WMP) of the Emax 2 switch-disconnector system. Its three-pole construction and 690 V AC rated operational voltage make it particularly suitable for switchboards where high-current switching, dependable isolation and convenient removal of the switching unit for servicing are required.

Key Advantages

• High-capacity 2000 A three-pole air switch disconnector.
• 42 kA short-time withstand current for 1 s for low-voltage distribution systems.

Reliable Withdrawable Isolation for High-Current Distribution

ABB SACE Emax 2 /MS switch disconnectors are designed to provide controlled switching and electrical isolation in low-voltage power distribution systems. Unlike an automatic circuit breaker equipped with an electronic protection trip unit, the /MS configuration is intended primarily for switching and isolation, with suitable protective devices elsewhere in the system providing the required automatic fault protection.

The withdrawable architecture allows the E2.2B/MS moving part to be separated from its corresponding fixed switchboard section, helping simplify inspection, servicing and equipment replacement. Combined with its 2000 A continuous-current rating and 42 kA 1-second short-time withstand capability, the 1SDA073495R1 provides a robust solution for high-current switchboards requiring dependable isolation and serviceable switchgear.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• High-current incoming and outgoing isolation duties.
• Transformer secondary distribution systems.
• Generator and standby power installations.
• Manufacturing and process plant switchgear.
• Withdrawable switchboard assemblies requiring serviceable switching devices.
