Why Choose the ABB E3H/E MS 2000 3P 750V DC W MP Switch Disconnector?
The ABB E3H/E MS 2000 3P 750V DC W MP, order code 1SDA059075R1, is a high-current three-pole withdrawable DC switch disconnector moving part from the ABB SACE Emax range. Designed for demanding direct-current power distribution systems, it combines a rated uninterrupted current of 2000 A with a rated operational voltage of 750 V DC.
This E3H/E MS model uses the ABB SACE Emax E3 frame with H performance and a withdrawable architecture. The W MP designation identifies the moving part of the withdrawable version, enabling the switching unit to be withdrawn from its compatible fixed section for inspection, servicing or replacement within suitable Emax switchgear.
The E3H/E MS 2000 provides a 2000 A rated operational and uninterrupted current, 1000 V rated insulation voltage and 12 kV rated impulse withstand voltage. A 40 kA rated short-time withstand current for 1 s supports demanding distribution applications, while the three-pole configuration is engineered for high-current 750 V DC switching and isolation.

Reliable 750 V DC Switching and Isolation
DC switch disconnectors provide a dependable means of switching and electrically isolating direct-current circuits for operational and maintenance requirements. Because DC current does not have the natural current zero crossing found in AC systems, purpose-designed switching equipment is particularly important for reliable isolation in high-voltage and high-current DC networks.
The ABB E3H/E MS configuration combines dedicated DC capability with a serviceable withdrawable Emax design. The moving part can be used with its compatible fixed section to create a withdrawable switching arrangement, while the 2000 A current rating and 40 kA for 1 s short-time withstand capability make this model suitable for demanding industrial 750 V DC distribution systems.
Typical Applications
- Industrial DC power distribution systems.
- 750 V DC electrical networks.
- DC busbar isolation and main switching.
- Withdrawable industrial switchgear assemblies.
- Renewable-energy and power-conversion installations.
- Transportation and infrastructure DC systems.
- High-current DC machinery and process installations.
