1SDA058885R1 ABB E3V/MS 1600 3P F HR Switch Disconnector 1600 A

Why Choose the ABB E3V/MS 1600 3P F HR Switch Disconnector?

The ABB E3V/MS 1600 3P F HR, order code 1SDA058885R1, is a heavy-duty SACE Emax air switch disconnector designed for high-current switching and isolation in low-voltage power distribution systems. Part of the proven ABB New Emax E3 series, this three-pole unit combines a 1600 A rated uninterrupted current with a fixed installation configuration for industrial switchboards and power distribution assemblies.

The E3V/MS 1600 is a fixed switch disconnector with rear horizontal terminals, providing a robust connection arrangement for engineered switchboard installations. The V performance level delivers 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, making this model suitable for demanding distribution systems with high prospective fault currents.

Rated for operation up to 690 V AC, with a rated insulation voltage of 1000 V and impulse withstand voltage of 12 kV, the E3V/MS 1600 provides dependable isolation for industrial power systems. As an Emax /MS switch disconnector, it is designed for switching and isolation duties without an overcurrent trip unit and is suitable for AC-23A utilisation applications in accordance with IEC 60947-3.

Reliable High-Current Isolation for Power Distribution

Switch disconnectors provide controlled switching and isolation of electrical circuits without incorporating the overcurrent trip functions of a conventional circuit breaker. This makes the ABB E3V/MS particularly suitable where circuit protection is provided elsewhere and a robust high-current switching device is required for operational isolation, maintenance and system segregation.

The E3V/MS platform is derived from ABB's SACE Emax air circuit-breaker architecture, retaining the robust mechanical construction and accessory possibilities of the corresponding breaker while omitting the overcurrent trip unit. Its high short-time withstand capability, fixed construction and rear horizontal connections make the 1600 A model well suited to engineered industrial switchboards and critical power distribution assemblies.

Typical Applications

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