1SDA058984R1 ABB E3S/MS 1600 4P W MP Switch Disconnector 1600 A

Why Choose the ABB E3S/MS 1600 4P W MP Switch Disconnector?

The ABB E3S/MS 1600 4P W MP, order code 1SDA058984R1, 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 four-pole device provides a rated uninterrupted current of 1600 A and forms the moving part of a withdrawable SACE Emax installation.

The E3S/MS 1600 combines ABB's service-friendly withdrawable architecture with the S short-circuit performance level. It provides 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 power 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 1600 is engineered for demanding low-voltage switchboards. ABB /MS switch disconnectors retain the overall dimensions and accessory possibilities of the corresponding Emax circuit-breaker platform while omitting the overcurrent trip unit, making them suitable where circuit protection is provided separately.

Key Advantages

• Heavy-duty 1600 A SACE Emax switch disconnector for high-current distribution and isolation.
• Four-pole withdrawable construction supports service-friendly switchboard design.
• 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 supports demanding distribution applications.
• AC-23A utilisation category supports switching of motor loads and other highly inductive loads.

Key Features

• ABB SACE Emax E3S/MS series.
• 1600 A rated uninterrupted current.
• Four-pole (4P) 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 short-circuit performance level.
• 165 kA peak rated short-circuit making capacity.
• Designed for AC-23A utilisation in accordance with IEC 60947-3.

Reliable High-Current Isolation for Power Distribution

ABB /MS switch disconnectors are derived from the corresponding SACE Emax circuit breakers, retaining their overall dimensions and the possibility of fitting accessories while differing through the absence of an overcurrent trip unit. The E3S/MS 1600 therefore provides dedicated switching and isolation where electrical protection is supplied separately, while its AC-23A utilisation category makes it suitable for switching motor loads and other highly inductive loads within its applicable ratings.

The withdrawable construction provides an important maintenance advantage because the moving part can be disconnected and withdrawn from its corresponding fixed section. Combined with its 1600 A rating, four-pole construction and 75 kA one-second withstand capability, the E3S/MS 1600 provides a robust solution for demanding industrial 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.
