Why Choose the ABB E4.2H/MS 3200 4p F HR Switch Disconnector?
The ABB E4.2H/MS 3200 4p F HR, order code 1SDA073458R1, 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 provides dependable performance for demanding industrial, commercial and infrastructure switchboards.
This E4.2H/MS model is a fixed switch-disconnector configuration intended for controlled switching and electrical isolation rather than automatic overcurrent protection. Its rear horizontal terminals provide a practical connection arrangement for integration with busbars and other high-current conductors in low-voltage switchgear assemblies.
With a rated uninterrupted current of 3200 A, a four-pole configuration and a rated short-time withstand current of 85 kA for 1 s, the E4.2H/MS is engineered for demanding power distribution applications. Its fixed construction and high withstand capability make it particularly suitable for main switchboards where reliable high-current isolation is essential.

Reliable High-Current Switching and Isolation
ABB Emax 2 /MS switch disconnectors are designed to provide dependable switching and electrical isolation of low-voltage power circuits. Unlike an automatic circuit breaker fitted with a protection trip unit, the /MS configuration is primarily intended to establish, interrupt and isolate the electrical path as part of a coordinated power distribution system.
The E4.2H/MS platform combines a substantial continuous-current rating with an 85 kA short-time withstand capability, making it suitable for switchboards exposed to high prospective fault currents. Its fixed configuration and rear horizontal terminals make the 1SDA073458R1 particularly well suited to high-capacity industrial power distribution assemblies.
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.
