Why Choose the ABB E4.2H MS/DC-E 1600A 1500V 4p F VR?
The ABB E4.2H MS/DC-E 1600A 1500V 4p F VR, order code 1SDA115406R1, is a high-performance SACE Emax 2 air switch-disconnector engineered for demanding direct-current power distribution systems operating at up to 1500 V DC. Built on the E4.2H frame, it combines a 1600 A rated uninterrupted current with four-pole switching and a fixed installation format.
The E4.2H MS/DC-E platform is specifically designed for high-voltage DC applications where dependable isolation and high short-time withstand capability are required. This H-performance version provides a rated short-time withstand current Icw of 85 kA for 1 s, making it suitable for robust industrial and energy-distribution architectures.
The 1SDA115406R1 is a 4-pole fixed (F) switch-disconnector with a vertical-rear connection configuration identified by VR. As an MS/DC-E switch-disconnector, it is intended for switching and isolation duties rather than electronic overcurrent protection, allowing system designers to coordinate protection using appropriate upstream or external protective devices.
Key Advantages
- Designed specifically for demanding 1500 V DC power distribution applications.
- High 1600 A rated uninterrupted current.
- 85 kA for 1 s rated short-time withstand current for high-fault-level systems.

High-Current Switching and Isolation at 1500 V DC
High-voltage DC networks place demanding requirements on switching equipment because direct current does not naturally pass through a zero-current point during each cycle as alternating current does. ABB's Emax 2 MS/DC-E platform is engineered specifically for these DC applications, providing dependable switching and isolation at system voltages up to 1500 V DC.
With a 1600 A current rating and 85 kA for 1 s short-time withstand capability, the E4.2H MS/DC-E is suited to high-power installations where substantial prospective fault currents may occur. As a switch-disconnector, its primary role is switching and isolation; the required overcurrent and short-circuit protection must be provided through the correctly engineered protection architecture of the installation.
Typical Applications
- High-voltage 1500 V DC distribution systems.
- Utility-scale photovoltaic power installations.
- Battery energy storage systems.
- Industrial DC distribution networks.
- Renewable-energy power conversion installations.
- High-current DC switchboards and distribution panels.
- Applications requiring a 1600 A fixed air switch-disconnector.
