Reliable Isolation for High-Power DC Distribution
DC switch disconnectors provide controlled switching and electrical isolation in direct-current power systems. Unlike AC circuits, DC networks do not have a natural current zero crossing during every cycle, making equipment specifically configured for the applicable DC voltage and current essential for dependable switching and isolation.
The ABB E2N/E MS 1600 is configured for high-current applications at 750 V DC. Its combination of a 1600 A current rating, three-pole architecture, fixed installation and rear horizontal terminals makes it suitable for industrial DC distribution equipment where robust switching performance and reliable circuit isolation are required.
Typical Applications
- Industrial DC power distribution systems.
- 750 V DC switchboards and distribution assemblies.
- Main incoming and feeder isolation in DC systems.
- High-current industrial DC electrical installations.
- Fixed switchgear requiring rear horizontal connections.
- Infrastructure, process and specialised DC power systems.
