1SDA061385R1 ABB E2N-A/MS 1200 3-Pole Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB E2N-A/MS 1200 3-Pole Switch-Disconnector?

The ABB E2N-A/MS 1200, order code 1SDA061385R1, is a high-current three-pole switch-disconnector moving part from the ABB SACE New Emax range. Designed for low-voltage power distribution systems, this E2N-A/MS configuration provides dependable switching and isolation of circuits with a 1200 A rated current.

Unlike an Emax air circuit breaker fitted with an electronic protection release, the E2N-A/MS is a switch-disconnector configuration intended primarily for circuit switching and isolation. It is therefore suited to installations where overcurrent protection is provided elsewhere in the electrical system and a robust high-current device is required for safe operational isolation.

This configuration features three-pole construction and a withdrawable moving-part execution. The withdrawable design supports integration into compatible ABB SACE New Emax switchgear and allows the moving part to be removed for inspection, servicing or replacement, providing flexibility in installations where maintainability and continuity of operation are important.

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 device is an important part of switchboard design, particularly where isolation is required for maintenance, system reconfiguration or operational control.

The ABB E2N-A/MS combines the mechanical switching platform of the SACE New Emax family with a switch-disconnector function rather than an electronic overcurrent protection release. In a correctly engineered system, associated protective devices provide the required fault and overload protection while the E2N-A/MS performs high-current switching and isolation duties.

Typical Applications

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