Why Choose the ABB 1SDA059053R1 E2N/E MS 2000 Switch Disconnector?
The ABB 1SDA059053R1 is a robust SACE Emax E2N/E MS switch disconnector designed for high-current DC isolation and switching duties in industrial low-voltage electrical systems. Rated at 2000 A and 750 V DC, this three-pole device provides dependable main-circuit isolation for demanding power distribution and control applications.
Part of the proven ABB SACE Emax family, the E2N/E MS 2000 is a fixed-mounted switch disconnector with rear horizontal terminals. Its E2 frame and N short-circuit performance level provide a durable platform for installations requiring high continuous-current capability, reliable isolation and integration within industrial switchboards and distribution assemblies.
This version features a 3-pole fixed configuration, 2000 A rated uninterrupted current and 750 V DC rated operational voltage. With a rated insulation voltage of 1000 V, rated impulse withstand voltage of 12 kV and short-time withstand current of 25 kA for 1 s, it is engineered for reliable service in substantial DC power installations.

Reliable High-Current DC Isolation and Switching
Switch disconnectors provide a means of switching and isolating electrical circuits so that downstream equipment can be separated from its power source when required. In high-current DC systems, appropriately rated switching equipment is particularly important because direct current does not naturally pass through a zero-current point during each cycle as alternating current does.
The ABB SACE Emax E2N/E MS 2000 combines a 2000 A current rating with a 750 V DC operational rating and fixed three-pole construction. Its substantial short-time withstand capability, rear horizontal connections and optional operating accessories make it well suited to integration into industrial DC distribution boards and purpose-built switchgear assemblies.
Typical Applications
- High-current DC power distribution systems.
- Industrial low-voltage switchboards and distribution assemblies.
- DC main-circuit isolation applications.
- Industrial power conversion and control installations.
- Large electrical plant and machinery distribution systems.
- OEM switchgear and power distribution equipment.
