1SDA058985R1 ABB E3S/MS 2000 3P W MP Switch Disconnector 2000 A

Why Choose the ABB E3S/MS 2000 3P W MP Switch Disconnector?

The ABB E3S/MS 2000 3P W MP, order code 1SDA058985R1, is a SACE Emax air switch disconnector moving part designed for high-current switching and isolation in low-voltage power distribution systems. Built on the ABB E3 frame, this three-pole unit provides a rated uninterrupted current of 2000 A and forms the moving part of a withdrawable SACE Emax installation.

The E3S/MS 2000 combines ABB's service-friendly withdrawable architecture with the S performance level. Its electrical characteristics include a rated short-time withstand current of 75 kA for 1 s and 65 kA for 3 s, together with a rated short-circuit making capacity of 165 kA peak, providing robust performance for demanding industrial distribution systems.

Rated for operation up to 690 V AC or 250 V DC, with a rated insulation voltage of 1000 V and rated impulse withstand voltage of 12 kV, the E3S/MS 2000 is engineered for substantial low-voltage distribution duties. ABB /MS switch disconnectors are derived from corresponding Emax circuit breakers, retaining their overall dimensions and accessory possibilities while omitting the overcurrent trip unit.

Key Advantages

• Heavy-duty 2000 A SACE Emax switch disconnector for high-current switching and isolation.
• Three-pole withdrawable construction supports service-friendly switchboard installations.
• Supplied as the moving part for a compatible SACE Emax withdrawable assembly.
• Rated for operation up to 690 V AC or 250 V DC.
• 75 kA short-time withstand current for 1 s provides robust fault-withstand capability.
• AC-23A utilisation category supports switching of motor loads and other highly inductive loads.

• ABB SACE Emax E3S/MS series.
• 2000 A rated uninterrupted current.
• Three-pole (3P) construction.
• Withdrawable (W) moving part (MP) configuration.
• 690 V AC / 250 V DC rated operational voltage.
• 1000 V rated insulation voltage.
• 12 kV rated impulse withstand voltage.
• S performance level.
• 165 kA peak rated short-circuit making capacity.
• Switch-disconnector design for AC-23A utilisation in accordance with IEC 60947-3.

Reliable High-Current Isolation for Power Distribution

ABB /MS switch disconnectors are derived from corresponding SACE Emax circuit breakers and retain their overall dimensions and ability to accommodate accessories while differing through the absence of an overcurrent trip unit. The E3S/MS 2000 therefore provides dedicated switching and isolation where electrical protection is provided separately, while its AC-23A utilisation category enables switching of motor loads and other highly inductive circuits within the applicable ratings.

The withdrawable design provides an important service advantage because the moving part can be disconnected and withdrawn from its corresponding fixed section. Combined with its 2000 A current rating, three-pole construction and 75 kA one-second withstand capability, the E3S/MS 2000 is well suited to demanding industrial, commercial and infrastructure power distribution assemblies.

Typical Applications

• Industrial low-voltage power distribution switchboards.
• Main incoming and distribution isolation.
• Withdrawable switchgear assemblies.
• Industrial plants and manufacturing facilities.
• Commercial and infrastructure power distribution systems.
• High-current feeder and busbar isolation.
