1SDA058899R1 ABB E3V/MS 3200 3P W MP Switch Disconnector 3200 A

Why Choose the ABB E3V/MS 3200 3P W MP Switch Disconnector?

The ABB E3V/MS 3200 3P W MP, order code 1SDA058899R1, is a heavy-duty SACE Emax air switch disconnector designed for high-current switching and isolation in demanding low-voltage power distribution systems. Part of the ABB New Emax E3 series, this three-pole unit provides a rated uninterrupted current of 3200 A and is supplied as the moving part for a withdrawable switch-disconnector installation.

The E3V/MS 3200 combines ABB's service-friendly withdrawable Emax construction with the high withstand capability required in major industrial distribution systems. Its V performance level provides a rated short-time withstand current of 85 kA for 1 s and 65 kA for 3 s, making it suitable for switchboards exposed to substantial prospective fault currents.

Rated for operation up to 690 V AC or 250 V DC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E3V/MS 3200 provides robust electrical performance for critical distribution duties. As an ABB /MS switch disconnector, it is derived from the corresponding Emax circuit-breaker platform but operates without an overcurrent trip unit, providing dedicated switching and isolation where protection is supplied separately.

Reliable High-Current Isolation for Power Distribution

Switch disconnectors provide controlled switching and isolation of electrical circuits without incorporating the overcurrent protection functions of a conventional circuit breaker. The ABB E3V/MS is therefore suited to systems where protection is provided separately and a robust high-current switching device is required for operational isolation, maintenance and segregation of major distribution circuits.

The withdrawable SACE Emax construction is particularly valuable in critical switchboards because the moving part can be disconnected and withdrawn from its corresponding fixed section for servicing or replacement. Combined with its 3200 A current rating and high short-time withstand capability, the E3V/MS 3200 provides a dependable solution for demanding industrial and infrastructure power systems.

Typical Applications

• High-current industrial low-voltage switchboards.
• Main incoming and distribution isolation.
• Withdrawable switchgear assemblies.
• Industrial plants and manufacturing facilities.
• Infrastructure and large commercial power distribution systems.
• High-current feeder and busbar isolation.
