1SDA059298R1 ABB E2N/MS 1000 1000A 3-Pole Withdrawable Switch-Disconnector

Why Choose the ABB E2N/MS 1000 3-Pole Withdrawable Switch-Disconnector?

The ABB E2N/MS 1000, order code 1SDA059298R1, is a robust 1000 A three-pole withdrawable air switch-disconnector moving part designed for isolation and switching duties in low-voltage power distribution systems. As part of the proven ABB SACE Emax E2N/MS series, it provides dependable high-current switching for industrial, commercial and infrastructure switchgear.

Unlike an Emax circuit breaker fitted with an electronic protection release, the E2N/MS is configured as a switch-disconnector for switching and isolation rather than automatic overcurrent protection. Its main-switch capability makes it suitable for applications where reliable circuit isolation is required and overcurrent protection is provided by separate upstream or downstream protective devices.

With a rated uninterrupted current of 1000 A and a maximum rated operational voltage of 690 V AC, the E2N/MS 1000 is suitable for demanding low-voltage distribution systems. This model is supplied as the three-pole moving part of a withdrawable switch-disconnector, allowing removal from the compatible fixed part for inspection, maintenance or replacement.

Key Advantages

• Heavy-duty 1000 A switch-disconnector for low-voltage power distribution.
• Three-pole configuration designed for three-phase electrical systems.
• Withdrawable moving-part construction supports efficient inspection and maintenance.
• Suitable for use as a main switch in compatible distribution assemblies.
• Maximum rated operational voltage of 690 V AC.
• 1000 A AC-21 rated operational current at 400 V AC.
• Lockable operating mechanism supports controlled circuit isolation.
• Part of the established ABB SACE Emax low-voltage switching platform.

Reliable Switching and Isolation for Power Distribution

Switch-disconnectors such as the ABB SACE Emax E2N/MS provide controlled switching and isolation of high-current low-voltage circuits. They allow sections of an electrical installation to be disconnected from the supply for operational control, inspection and maintenance while providing the isolation functionality required within a coordinated distribution system.

The E2N/MS 1000 is designed as a switch-disconnector rather than an automatic overcurrent protective circuit breaker, so suitable external protection must form part of the overall installation design. Its withdrawable construction makes it particularly useful in switchboards where maintainability, operational flexibility and straightforward removal of the switching device are important.

Typical Applications

• Low-voltage main distribution switchboards.
• Main switching and circuit isolation.
• Industrial power distribution systems.
• Commercial building electrical distribution.
• Manufacturing and process plant switchgear.
• Three-phase distribution systems.
• Infrastructure and utility installations.
• Switchgear assemblies requiring withdrawable isolation devices.
