Why Choose the ABB E3N/MS 2500 4P W MP Switch Disconnector?
The ABB E3N/MS 2500 4P W MP, order code 1SDA058988R1, is a high-current SACE Emax air switch disconnector moving part designed for dependable switching and isolation in low-voltage industrial power distribution systems. As part of the ABB E3N/MS range, this four-pole unit provides a 2500 A current rating for demanding switchboard and power distribution applications.
ABB Emax /MS switch disconnectors are derived from the corresponding Emax circuit-breaker platform while operating without an overcurrent trip unit. The E3N/MS family is designed in accordance with IEC 60947-3 and is suitable for AC-23A utilisation, supporting the switching of motor loads and other highly inductive loads as well as general high-current isolation duties.
This four-pole withdrawable moving part combines a rated service voltage of up to 690 V AC with a 65 kA short-time withstand current for 1 s. Its withdrawable Emax construction allows integration into compatible switchgear where maintainability, isolation and high-current distribution performance are important.

Reliable Isolation for High-Current Power Distribution
Air switch disconnectors provide controlled switching and isolation of electrical circuits without incorporating the overcurrent protection functions of a circuit-breaker trip unit. The ABB E3N/MS platform retains the robust construction and accessory possibilities of the corresponding SACE Emax circuit-breaker platform while providing dedicated switch-disconnector functionality.
The E3N/MS 2500 is particularly suited to high-current distribution systems where substantial short-time withstand capability and withdrawable switchgear construction are required. The moving-part format enables the device to be used with the appropriate fixed portion of a compatible Emax withdrawable assembly, supporting maintenance and isolation requirements in industrial switchboards.
Typical Applications
- Industrial low-voltage power distribution systems.
- Main incoming and feeder isolation in switchboards.
- High-current four-pole distribution assemblies.
- Withdrawable industrial switchgear installations.
- Motor and highly inductive load switching applications.
- Manufacturing, infrastructure and process-industry electrical systems.
