1SDA059300R1 ABB E2N/MS1000 1000 A 4-Pole Withdrawable Switch-Disconnector

Why Choose the ABB 1SDA059300R1 E2N/MS1000 Switch-Disconnector?

The ABB 1SDA059300R1 is a robust SACE Emax E2N/MS 1000 A four-pole switch-disconnector moving part designed for dependable switching and isolation in low-voltage electrical distribution systems. Part of the ABB New Emax product family, this unit combines high-current switching capability with the proven E2N platform for demanding industrial and commercial switchboard applications.

The E2N/MS1000 is rated at 1000 A and features a four-pole configuration, making it suitable for systems requiring simultaneous switching and isolation of four conductors. As a switch-disconnector rather than an overcurrent-protective circuit breaker, the E2N/MS is intended primarily for switching and isolation duties within a suitably protected electrical distribution system.

This model is supplied as a withdrawable moving part (W MP) for use with the corresponding SACE Emax fixed part. The withdrawable construction supports efficient inspection, servicing and replacement while providing the robust electrical and mechanical performance required in high-current low-voltage switchgear.

Reliable Switching and Isolation for Power Distribution

Switch-disconnectors such as the ABB SACE Emax E2N/MS provide dependable switching and isolation within low-voltage electrical distribution systems. They enable circuits to be disconnected for operational control, inspection and maintenance while providing the current-carrying and short-time withstand performance required in demanding industrial switchboards.

The E2N/MS1000 combines a 1000 A current rating with four-pole switching and a withdrawable moving-part configuration. Its high short-time withstand capability and maintainable construction make the 1SDA059300R1 particularly suitable for power distribution systems requiring robust isolation equipment that can be conveniently withdrawn from the switchboard assembly.

Typical Applications

• Industrial low-voltage switchboards.
• Main power isolation and switching.
• Three-phase and four-wire distribution systems.
• Manufacturing and process facilities.
• Commercial building power distribution.
• Electrical distribution panels and assemblies.
• Infrastructure and utility installations.
• Systems requiring withdrawable high-current switch-disconnectors.
