Why Choose the ABB E4.2N/MS 3200 4p F HR Switch Disconnector?
The ABB E4.2N/MS 3200 4p F HR, order code 1SDA073457R1, is a high-performance four-pole air switch disconnector from the ABB SACE Emax 2 family, designed for reliable high-current switching and isolation in low-voltage power distribution systems. Built on the robust Emax 2 E4.2 platform, it is well suited to demanding industrial, commercial and infrastructure switchboards.
The E4.2N/MS is a switch-disconnector configuration intended to provide controlled switching and electrical isolation rather than automatic overcurrent protection. Its fixed-mounted construction and orientable rear horizontal terminals simplify integration into power distribution assemblies while providing the mechanical strength required for high-current applications.
With a rated uninterrupted current of 3200 A, a four-pole configuration and a rated short-time withstand current of 66 kA for 1 s, the E4.2N/MS provides dependable performance for major distribution circuits. The E4.2 frame is particularly suited to high-current switchboard applications where compact installation, robust isolation and reliable switching are required.

Reliable High-Current Switching and Isolation
ABB Emax 2 /MS switch disconnectors are designed to switch and isolate low-voltage power circuits without the automatic protection functions associated with an air circuit breaker trip unit. This makes them suitable for installations where a dedicated high-current isolating device is required as part of the overall protection and distribution architecture.
The E4.2N/MS platform combines a substantial continuous-current rating with high short-time withstand capability. Its fixed configuration and rear horizontal terminals make the 1SDA073457R1 particularly suitable for main distribution boards, industrial switchgear and other high-power assemblies requiring dependable switching and isolation.
Typical Applications
- Main low-voltage distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- High-current circuit isolation and sectionalising.
- Power distribution and control assemblies.
- OEM switchgear and panel-building applications.
