Why Choose the ABB E2.2N/MS 1600 4p F HR Switch Disconnector?
The ABB E2.2N/MS 1600 4p F HR, order code 1SDA073448R1, is a high-performance four-pole air switch disconnector from the ABB SACE Emax 2 family, designed for dependable switching and isolation in low-voltage power distribution systems. Built on the Emax 2 E2.2 platform, it combines robust construction with high short-time withstand capability for demanding industrial, commercial and infrastructure installations.
The E2.2N/MS is designed as a switch disconnector in accordance with IEC 60947-3. The /MS configuration provides switching and isolation functionality without the automatic protection trip unit used in an Emax 2 circuit breaker, while retaining the dimensions and accessory options associated with the Emax 2 platform.
With a rated uninterrupted current of 1600 A, a four-pole configuration and a rated short-time withstand current of 66 kA for 1 s, the E2.2N/MS is suitable for high-current low-voltage distribution. Its fixed construction and horizontally orientated rear terminals provide a practical arrangement for integration into switchboards and power distribution assemblies.

Reliable Switching and Isolation for Power Distribution
ABB Emax 2 /MS switch disconnectors provide reliable switching and electrical isolation of low-voltage circuits. When the device is in the open position, the separation between its main contacts provides the isolation required to electrically separate downstream equipment from the supply.
The E2.2N/MS combines a high continuous-current rating with substantial short-time withstand performance, making it well suited to main distribution boards and industrial switchgear. Its fixed configuration and rear horizontal terminals facilitate integration into power distribution assemblies where robust high-current switching and isolation are 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 power distribution assemblies.
- OEM switchgear and panel-building applications.
