1SDA058962R1 ABB E2N/MS 1600 1600A 4-Pole Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB E2N/MS 1600 4-Pole Withdrawable Switch-Disconnector?

The ABB E2N/MS 1600 is a robust 1600 A four-pole withdrawable switch-disconnector moving part designed for dependable switching and isolation in demanding low-voltage electrical distribution systems. Part of the proven ABB SACE Emax E2 series, this N-performance device combines substantial current-carrying capability with a withdrawable construction for service-friendly integration into industrial, commercial and infrastructure switchgear.

ABB Emax switch-disconnectors identified by the /MS designation are derived from the corresponding circuit breakers, retaining their overall dimensions and compatibility with applicable Emax accessories while omitting the overcurrent trip unit. The E2N/MS can be used according to AC-23A utilisation category in accordance with IEC 60947-3, making it suitable for switching motor loads and other highly inductive loads as well as general isolation duties.

The 1SDA058962R1 configuration is rated at 1600 A and features a four-pole withdrawable moving part (W MP). With a rated operational voltage of up to 690 V AC, a 55 kA one-second short-time withstand current and a 121 kA peak short-circuit making capacity, it provides robust switching and isolation performance for substantial low-voltage power-distribution systems.

Reliable High-Current Withdrawable Switching and Isolation

The ABB E2N/MS 1600 provides a dependable means of making, carrying and isolating high-current electrical circuits without an integrated overcurrent trip unit. Its 55 kA one-second short-time withstand rating, 42 kA three-second withstand rating and 121 kA peak making capacity support use in substantial distribution systems when suitable overload and short-circuit protection is coordinated elsewhere in the installation.

As a withdrawable moving part, the E2N/MS 1600 can be separated from its corresponding fixed part for inspection, servicing or replacement. Combined with its 1600 A current rating, four-pole architecture and established SACE Emax mechanical platform, the 1SDA058962R1 is particularly well suited to switchboards where dependable isolation, high electrical performance and service accessibility are required.
