1SDA073531R1 ABB E2.2B/MS 1600 4p WMP Switch-Disconnector

Why Choose the ABB E2.2B/MS 1600 4p WMP Switch-Disconnector?

The ABB E2.2B/MS 1600 4p WMP, order code 1SDA073531R1, is a high-current four-pole withdrawable air switch-disconnector moving part from the ABB SACE Emax 2 range. Designed for dependable switching and isolation in low-voltage power distribution systems, it provides a rated uninterrupted current of 1600 A and a rated operational voltage of 690 V AC.

This E2.2B/MS configuration is the moving part of a withdrawable switch-disconnector, designed for installation with the corresponding Emax 2 fixed part. The withdrawable architecture supports efficient inspection, servicing and replacement, while the four-pole arrangement provides switching and isolation of three-phase circuits together with the neutral conductor where required.

With a rated short-time withstand current of 42 kA for 1 s, the E2.2B/MS 1600 provides robust performance for industrial, commercial and infrastructure distribution systems. Its combination of high current capacity, withdrawable construction and four-pole switching makes it a practical solution for maintainable low-voltage switchgear assemblies.

Reliable Withdrawable Switching and Isolation

The ABB E2.2B/MS provides a dependable means of switching and electrically isolating high-current sections of low-voltage power distribution systems. Its withdrawable moving-part construction allows the device to be separated from the corresponding fixed part, supporting planned inspection, maintenance and replacement while retaining the robust architecture of the SACE Emax 2 platform.

With a 1600 A uninterrupted current rating and 42 kA for 1 s short-time withstand capability, the E2.2B/MS 1600 is well suited to substantial distribution loads. Its four-pole arrangement makes it particularly useful in three-phase systems where the neutral conductor must also be switched and isolated.

Typical Applications

• Low-voltage main and sub-distribution switchboards.
• Industrial three-phase power distribution systems with neutral switching.
• Commercial and infrastructure electrical installations.
• Switchboards requiring withdrawable high-current isolation devices.
• Manufacturing and process plant distribution systems.
• Electrical assemblies requiring dependable 1600 A four-pole switching and isolation.
