1SDA073555R1 ABB E6.2H/f/MS 5000 4p WMP Emax 2 Switch Disconnector 5000 A

Why Choose the ABB E6.2H/f/MS 5000 4p WMP Emax 2 Switch Disconnector?

The ABB E6.2H/f/MS 5000 4p WMP, order code 1SDA073555R1, is a high-capacity four-pole air switch disconnector moving part from the ABB SACE Emax 2 range, designed for switching and isolation duties in demanding low-voltage electrical distribution systems. Built on the E6.2 frame, this withdrawable moving part provides a 5000 A rated uninterrupted current for major industrial, infrastructure and critical-power installations.

The E6.2H/f/MS combines substantial current capacity with exceptional short-time withstand performance. Its H performance level provides a rated short-time withstand current of 100 kA for 1 s and 100 kA for 3 s, making it suitable for high-power distribution systems where substantial prospective fault currents must be accommodated.

The /f configuration identifies this model as a four-pole device with a full-size neutral rated at 100% of Iu. With a rated operational voltage of 690 V AC, a 1000 V AC insulation voltage and withdrawable construction, the E6.2H/f/MS 5000 is engineered for large switchboards where dependable isolation, high current capacity and maintainability are essential.

High-Current Four-Pole Switching and Isolation

The ABB E6.2H/f/MS is engineered for controlled switching and dependable isolation in large low-voltage power distribution systems. With a rated uninterrupted current of 5000 A and a short-time withstand capability of 100 kA for both 1 s and 3 s, it is particularly suited to high-capacity installations with substantial prospective fault-current levels.

Its full-size fourth pole provides a neutral current rating equal to the phase poles, making the device suitable for four-wire distribution systems requiring a 100% rated neutral. The withdrawable E6.2 moving part can be removed from its compatible fixed section, supporting inspection, maintenance and replacement in major industrial and critical-power switchboards.

Typical Applications

• High-current industrial low-voltage switchboards.
• Four-wire distribution systems requiring a full-size neutral.
• Main incoming and distribution switchboards.
• Data centres and critical-power infrastructure.
• Large manufacturing and process facilities.
• High-fault-level switching and isolation applications.
• Utility and infrastructure electrical distribution.
• Large commercial and industrial installations requiring withdrawable switching equipment.
