1SDA058898R1 ABB E3V/MS 3200 4P F HR Switch Disconnector 3200 A

Why Choose the ABB E3V/MS 3200 4P F HR Switch Disconnector?

The ABB E3V/MS 3200 4P F HR, order code 1SDA058898R1, 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 four-pole unit provides a rated uninterrupted current of 3200 A and a fixed installation format for industrial switchboards and engineered power distribution assemblies.

The E3V/MS 3200 combines a four-pole fixed construction with rear flat horizontal terminals for integration into high-current switchboard busbar systems. Its V performance level provides a rated short-time withstand current of 85 kA for 1 s and 65 kA for 3 s, together with a rated short-circuit making capacity of 187 kA peak, providing robust performance in installations with 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 a rated impulse withstand voltage of 12 kV, the E3V/MS 3200 is engineered for dependable high-power distribution. ABB /MS switch disconnectors are derived from the corresponding Emax circuit breakers but omit the overcurrent trip unit, making them suitable for switching and isolation duties where circuit protection is provided separately.

Key Advantages

• Heavy-duty 3200 A SACE Emax switch disconnector for high-current distribution systems.

• Designed for high-current switching and isolation in industrial low-voltage distribution systems.

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 fault and overload protection is provided separately and a robust switching device is required for operational isolation, maintenance and segregation of high-current distribution circuits.

The SACE Emax /MS design retains the overall construction and accessory possibilities of the corresponding Emax circuit-breaker platform while operating as a dedicated switch disconnector. With its 3200 A current rating, four-pole construction, fixed installation format and high short-time withstand capability, this E3V/MS model is particularly suited to major industrial switchboards and critical power distribution infrastructure.

Typical Applications

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