1SDA058894R1 ABB E3V/MS 2500 2500A 4-Pole Fixed Switch-Disconnector

Why Choose the ABB E3V/MS 2500 4-Pole Fixed Switch-Disconnector?

The ABB E3V/MS 2500 is a high-performance 2500 A four-pole switch-disconnector designed for dependable switching and isolation in demanding low-voltage electrical distribution systems. Part of the ABB SACE Emax E3 series, this V-performance device combines high-current capability with robust fixed construction for industrial, commercial and infrastructure switchgear.

Unlike an Emax circuit breaker equipped with an electronic overcurrent trip unit, the E3V/MS is a switch-disconnector specifically designed for switching and isolation. ABB Emax /MS switch-disconnectors are suitable for AC-23A utilisation category applications in accordance with IEC 60947-3, including the switching of motor loads and other highly inductive loads.

The 1SDA058894R1 configuration has a rated uninterrupted current of 2500 A and features a four-pole fixed construction with horizontal rear terminals. With a rated operational voltage of 690 V AC, a 1000 V insulation voltage and an 85 kA one-second short-time withstand current, it provides a robust isolation solution for high-fault-level distribution systems.

Key Advantages

• Heavy-duty ABB SACE Emax E3V/MS switch-disconnector for low-voltage distribution.
• 2500 A rated uninterrupted current for demanding high-current applications.

High-Performance Switching and Isolation for Power Distribution

ABB SACE Emax /MS switch-disconnectors are derived from the corresponding Emax circuit-breaker platform and retain its robust construction and accessory flexibility while omitting the integrated overcurrent trip unit. The E3V/MS is therefore particularly suited to installations requiring high-current switching and positive circuit isolation with protection coordinated elsewhere in the distribution system.

The E3V/MS 2500 combines its 2500 A current rating with an 85 kA one-second short-time withstand capability and a peak making capacity of 187 kA. Its four-pole fixed construction and horizontal rear connections make it a practical choice for substantial switchboards where high electrical performance and straightforward busbar integration are required.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Main and feeder switching applications.
• Four-pole electrical isolation.
• Manufacturing and process plants.
• Commercial and infrastructure electrical installations.
• Motor and highly inductive load switching under AC-23A duty.
• High-fault-level distribution systems requiring strong short-time withstand performance.
