1SDA061393R1 ABB E2N-A/MS 800 A 3-Pole Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB E2N-A/MS 800 1SDA061393R1 Switch-Disconnector?

The ABB 1SDA061393R1 is an E2N-A/MS 800 A three-pole withdrawable switch-disconnector moving part from the ABB SACE Emax / New Emax range. Designed for switching and isolation duties in low-voltage power distribution systems, it provides a robust solution for industrial and commercial switchboards where dependable high-current circuit isolation is required.

The MS switch-disconnector configuration is intended primarily for circuit switching and isolation rather than the electronic overcurrent protection provided by PR-series trip-unit versions of ABB Emax circuit breakers. This makes the E2N-A/MS suitable for installations where the required overcurrent protection is provided elsewhere in the electrical system and a dedicated switching and isolation device is required.

The 1SDA061393R1 features a three-pole withdrawable moving-part construction and is designed for use with a compatible ABB SACE Emax withdrawable fixed part. Its withdrawable format supports convenient inspection, maintenance and replacement within switchboard installations, while the 800 A rating makes it suitable for substantial three-phase distribution circuits.

Reliable Switching and Isolation for Power Distribution

Switch-disconnectors perform an important role in low-voltage distribution systems by providing a means of switching and isolating electrical circuits. Unlike an Emax circuit breaker equipped with a PR-series electronic protection release, an MS switch-disconnector is primarily intended to provide switching and isolation, with the necessary overcurrent protection coordinated elsewhere within the installation.

The ABB E2N-A/MS platform provides a practical solution where robust three-phase isolation and a serviceable withdrawable design are required. The moving portion can be used with the appropriate ABB SACE Emax withdrawable fixed part, helping simplify inspection and maintenance in industrial and commercial power distribution switchboards.

Typical Applications

• Low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process plant switchgear.
• Bus coupler and distribution switching applications.
• Power distribution and control assemblies.
• Three-phase circuits requiring withdrawable 800 A switching and isolation.
