1SDA061413R1 ABB E3N-A/MS 2500 A 3-Pole Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB E3N-A/MS 2500 1SDA061413R1 Switch-Disconnector?

The ABB 1SDA061413R1 is an E3N-A/MS 2500 A three-pole withdrawable switch-disconnector moving part from the ABB SACE Emax / New Emax range. Designed for switching and isolation duties in high-current low-voltage power distribution systems, it provides a robust solution for industrial, commercial and infrastructure switchboards where dependable 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 E3N-A/MS suitable for installations where the required overcurrent protection is provided elsewhere in the electrical system and a dedicated high-current switching and isolation device is required.

The 1SDA061413R1 features a 2500 A rating, three-pole construction and a withdrawable moving portion (MP) designed for use with a compatible ABB SACE Emax fixed part. Its withdrawable format supports efficient inspection, maintenance and replacement within switchboard installations, while its UL configuration suits compatible low-voltage distribution applications.

Reliable High-Current Switching and Isolation

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 E3N-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, maintenance and replacement in high-current industrial and commercial power distribution switchboards.

Typical Applications

• High-current low-voltage main distribution switchboards.
• Industrial power distribution systems.
• Large commercial and infrastructure electrical installations.
• Manufacturing and process plant switchgear.
• Bus coupler and distribution switching applications.
• Power distribution and control assemblies.
• Three-phase circuits requiring withdrawable 2500 A switching and isolation.
