1SDA073548R1 ABB E6.2X/MS 4000 4p WMP Switch-Disconnector

Why Choose the ABB E6.2X/MS 4000 4p WMP Switch-Disconnector?

The ABB E6.2X/MS 4000 4p WMP, order code 1SDA073548R1, is a high-current four-pole withdrawable air switch-disconnector moving part from the ABB SACE Emax 2 range. Designed for demanding low-voltage power distribution systems, it provides a rated uninterrupted current of 4000 A and is suitable for operational voltages up to 690 V AC.

This E6.2X/MS configuration is the moving part of a withdrawable switch-disconnector, designed for installation with the corresponding Emax 2 fixed part. Its withdrawable architecture supports inspection, servicing and replacement in high-capacity switchboards, while the four-pole arrangement enables simultaneous switching and isolation of three phase conductors and the neutral.

With a rated short-time withstand current of 120 kA for 1 s, the E6.2X/MS 4000 delivers exceptional withstand capability for demanding distribution systems. Its combination of 4000 A current capacity, X performance level and four-pole withdrawable construction makes it particularly suitable for industrial and infrastructure installations with high prospective fault levels.

Key Advantages

• Very high 4000 A rated uninterrupted current for major low-voltage distribution systems.
• Exceptional 120 kA short-time withstand current for 1 s.
• Four-pole configuration supports switching and isolation of three-phase systems with neutral.

Reliable High-Current Withdrawable Switching and Isolation

The ABB E6.2X/MS provides a dependable means of switching and electrically isolating very high-current sections of low-voltage power distribution systems. Its withdrawable construction enables the moving part to be separated from the corresponding fixed part, supporting planned inspection, servicing and replacement while retaining the robust high-current architecture of the SACE Emax 2 platform.

With a 4000 A uninterrupted current rating and exceptional 120 kA for 1 s short-time withstand capability, the E6.2X/MS 4000 is engineered for substantial distribution loads and installations with demanding fault-withstand requirements. Its four-pole arrangement makes it particularly suitable for three-phase systems where the neutral conductor must also be switched and isolated.

Typical Applications

• High-capacity low-voltage main distribution switchboards.
• Industrial three-phase power distribution systems with neutral switching.
• Large commercial and infrastructure electrical installations.
• Switchboards requiring withdrawable high-current isolation devices.
• Manufacturing, utilities and process plant power distribution systems.
• Electrical assemblies requiring 4000 A switching with very high short-time withstand capability.
