1SDA058888R1 ABB SACE Emax E3V/MS 1600 A 4-Pole Withdrawable Switch-Disconnector Moving Part

Why Choose the ABB 1SDA058888R1 Emax E3V/MS 1600 Switch-Disconnector?

The ABB 1SDA058888R1 is a SACE Emax E3V/MS 1600 four-pole withdrawable switch-disconnector moving part designed for high-current switching and isolation in low-voltage power distribution systems. Identified by ABB as E3V/MS 1600 4p W MP new, this configuration combines a 1600 A current rating with a withdrawable construction for integration into compatible SACE Emax switchgear.

The E3V/MS configuration is designed primarily for switching and electrical isolation rather than automatic overcurrent protection. Its four-pole construction enables switching across four conductors, while the withdrawable moving-part design allows the device to form part of a draw-out assembly for convenient isolation, inspection and maintenance.

The E3V/MS 1600 is rated for 690 V AC operation and provides a substantial 85 kA short-time withstand current for 1 s and 65 kA for 3 s. Combined with a 1000 V insulation rating and 12 kV impulse withstand voltage, these characteristics make the 1SDA058888R1 suitable for demanding industrial power distribution installations.

High-Performance Withdrawable Switching and Isolation

ABB SACE Emax switch-disconnectors provide controlled switching and isolation for high-current electrical distribution systems. The /MS configuration is intended for switching and disconnection duties, while system overcurrent protection can be coordinated using appropriate protective equipment elsewhere within the installation.

The E3V/MS 1600 combines a 1600 A current rating with an 85 kA for 1 s short-time withstand capability. Its four-pole withdrawable moving-part construction provides additional operational flexibility, allowing it to be used within compatible draw-out switchgear where reliable isolation and maintainability are important.
