1SDA061423R1 ABB E3S-A/MS 2000 3-Pole Fixed Switch-Disconnector

Why Choose the ABB E3S-A/MS 2000 3-Pole Switch-Disconnector?

The ABB E3S-A/MS 2000, order code 1SDA061423R1, is a high-current three-pole fixed switch-disconnector from the ABB SACE New Emax range. Designed for low-voltage power distribution systems, this E3S-A/MS configuration provides dependable switching and isolation of circuits with a 2000 A rated current.

Unlike a New Emax air circuit breaker equipped with an electronic protection release, the E3S-A/MS is a switch-disconnector configuration intended primarily for circuit switching and isolation. It is suitable for installations where overload and short-circuit protection is provided elsewhere in the electrical system and a robust high-current switching device is required for operational isolation.

This configuration features a 2000 A rated current, three-pole construction, fixed execution and horizontal rear terminals. The fixed arrangement provides permanent integration into compatible low-voltage switchboards, while the rear terminal configuration supports practical connection to busbars and conductors within the switchgear assembly.

Reliable Switching and Isolation for Low-Voltage Distribution

Switch-disconnectors provide a means of switching and isolating electrical circuits so equipment or sections of a distribution system can be disconnected when required. In high-current installations, a robust switching and isolation device is an important part of switchboard design, particularly where circuits need to be isolated for maintenance, system reconfiguration or operational control.

The ABB E3S-A/MS combines the switching platform of the SACE New Emax family with a switch-disconnector function rather than an electronic overcurrent protection release. In a correctly engineered electrical system, associated protective devices provide the required overload and fault protection while the E3S-A/MS performs high-current switching and isolation duties.

Typical Applications

• Main and sub-main low-voltage distribution switchboards.
• High-current industrial electrical distribution systems.
• Commercial and infrastructure power distribution.
• Manufacturing and process facilities.
• Fixed switchgear and power distribution assemblies.
• High-current feeder and busbar switching and isolation.
