1SDA073492R1 ABB E2.2B/MS 1600 3p WMP Switch Disconnector

Why Choose the ABB E2.2B/MS 1600 3p WMP Switch Disconnector?

The ABB E2.2B/MS 1600 3p WMP, order code 1SDA073492R1, is a robust three-pole withdrawable air switch disconnector from the ABB SACE Emax 2 family, designed for reliable switching and electrical isolation in low-voltage power distribution systems. Based on the Emax 2 E2.2 platform, it combines a high 1600 A continuous-current rating with withdrawable construction for industrial, commercial and infrastructure switchboards.

The E2.2B/MS is designed as a switch disconnector rather than an automatic protection circuit breaker. The /MS configuration provides switching and isolation functionality without an electronic protection trip unit, while the withdrawable moving-part format enables the device to be disconnected from its compatible fixed part for inspection, servicing and maintenance.

With a rated uninterrupted current of 1600 A, a three-pole configuration and B performance level, the E2.2B/MS is suited to demanding three-phase distribution applications. Its Emax 2 architecture provides robust mechanical construction and flexible integration into low-voltage switchgear where dependable high-current isolation is required.

Key Advantages

• Heavy-duty 1600 A air switch disconnector for low-voltage power distribution.
• Three-pole configuration for three-phase circuit switching and isolation.
• Withdrawable moving-part design supports convenient inspection and maintenance.
• B performance level for dependable distribution-system operation.
• Switch-disconnector configuration without an automatic protection trip unit.
• Built on the proven ABB SACE Emax 2 E2.2 platform.

Key Features

• ABB SACE Emax 2 E2.2B/MS series.
• 1600 A rated uninterrupted current.
• 3-pole configuration.
• Withdrawable moving-part construction.
• B performance level.
• Designed for high-current switching and electrical isolation.

Reliable Switching and Isolation for Power Distribution

ABB Emax 2 /MS switch disconnectors are designed to establish, carry and interrupt current under normal circuit conditions while providing electrical isolation when required. Unlike Emax 2 air circuit breakers equipped with protection trip units, the /MS configuration is intended primarily for switching and isolation within a coordinated low-voltage distribution system.

The withdrawable E2.2B/MS architecture allows the moving part to be separated from its compatible fixed part, supporting easier servicing and equipment replacement. Combined with its 1600 A current rating, the 1SDA073492R1 is well suited to switchboards requiring high-current switching together with the service flexibility of withdrawable equipment.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical installations.
• Three-phase circuit isolation and sectionalising.
• Withdrawable switchgear requiring maintenance flexibility.
• OEM switchgear and panel-building applications.
