The ABB E3S/MS 2500 3P W MP, order code 1SDA058989R1, 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 E3S/MS switch-disconnector range, this three-pole unit provides a 2500 A rated uninterrupted current for demanding switchboard and distribution applications.
ABB Emax /MS switch disconnectors are derived from the corresponding Emax circuit-breaker platform, retaining the overall construction and accessory possibilities while operating without an overcurrent trip unit. The /MS range is designed for switch-disconnector duties and can be used in AC-23A utilisation category applications in accordance with IEC 60947-3.
This three-pole withdrawable moving part has a maximum rated operational voltage of 690 V AC and the E3S/MS performance level provides a 75 kA short-time withstand current for 1 s. Its withdrawable configuration is suited to compatible SACE Emax switchgear where high-current isolation, maintainability and dependable power distribution are required.
Air switch disconnectors provide controlled switching and isolation of electrical circuits without the overcurrent protection functions associated with a circuit-breaker trip unit. ABB Emax /MS devices retain the robust platform and accessory possibilities of the corresponding Emax circuit-breakers while providing dedicated switch-disconnector functionality for low-voltage distribution systems.
The E3S/MS 2500 combines a substantial 2500 A current rating with high short-time withstand capability. Its withdrawable moving-part construction supports integration into compatible Emax assemblies where maintainability, circuit isolation and reliable high-current switching are important design requirements.
