1SDA073447R1 ABB E2.2B/MS 1600 4p F HR Switch Disconnector

Why Choose the ABB E2.2B/MS 1600 4p F HR Switch Disconnector?

The ABB E2.2B/MS 1600 4p F HR, order code 1SDA073447R1, is a robust four-pole air switch disconnector from the ABB SACE Emax 2 family, designed for reliable switching and isolation in low-voltage power distribution systems. Built on the proven Emax 2 E2.2 platform, it provides dependable high-current performance for industrial, commercial and infrastructure switchboards.

This E2.2B/MS device is designed specifically for switching and isolation rather than automatic overcurrent protection. Its fixed-mounted construction provides a secure installation within low-voltage assemblies, while the horizontally orientated rear terminals support practical integration with busbars and power connections in switchboard applications.

With a rated uninterrupted current of 1600 A, a four-pole configuration and a rated short-time withstand current of 42 kA, the E2.2B/MS is suited to demanding electrical distribution applications. It is rated for operation up to 690 V AC and offers the electrical and mechanical durability required for dependable service in modern power distribution systems.

Reliable Switching and Isolation for Power Distribution

ABB Emax 2 /MS switch disconnectors provide controlled switching and electrical isolation of low-voltage circuits. Unlike an automatic circuit breaker equipped with a protection trip unit, a switch disconnector is primarily intended to establish or interrupt the electrical path and provide isolation for downstream equipment.

The E2.2B/MS platform combines high current capacity with strong short-time withstand performance and durable mechanical construction. This makes the 1SDA073447R1 particularly suitable for main switchboards, industrial distribution assemblies and installations where reliable high-current isolation is required.

Typical Applications

• Main low-voltage distribution switchboards.
• Industrial power distribution systems.
• Commercial and infrastructure electrical installations.
• High-current circuit isolation and sectionalising.
• Industrial control and distribution panels.
• OEM switchgear and panel-building applications.
