Reliable High-Voltage DC Isolation and Switching
Switch disconnectors provide controlled switching and electrical isolation so that downstream circuits and equipment can be separated from their power source when required. DC systems place particular demands on switching equipment because direct current does not naturally cross zero during each electrical cycle, making equipment with the correct DC voltage and current ratings essential.
The ABB SACE Emax E3H/E MS range is engineered for demanding DC distribution applications. This 1250 A, 1000 V DC four-pole moving part combines withdrawable construction with a substantial 40 kA for 1 s short-time withstand rating, making it well suited to industrial switchgear where high-current capability, reliable isolation and equipment serviceability are required.
Typical Applications
- High-current 1000 V DC power distribution systems.
- Industrial withdrawable switchboards and switchgear.
- High-voltage DC main-circuit isolation.
- Industrial power conversion and DC distribution installations.
- Large machinery and electrical plant power systems.
- OEM power distribution and switchgear assemblies.
