Reliable Switching and Isolation for Power Distribution

Switch disconnectors such as the ABB E2.2H/MS provide controlled switching and dependable isolation of electrical circuits in low-voltage distribution systems. Unlike an automatic circuit breaker equipped with a protection release, the /MS switch-disconnector version is designed specifically for switching and isolation duties, providing the required isolating distance between its main contacts when in the open position.

The Emax 2 platform is engineered for modern switchboards where high current capacity, robust short-time withstand performance and flexible operation are important. The withdrawable E2.2H/MS moving part can be disconnected and removed from its compatible fixed section, helping simplify inspection and maintenance in industrial and critical power distribution installations.

Typical Applications

• Industrial low-voltage switchboards.
• Main power distribution panels.
• High-current electrical distribution systems.
• Commercial and infrastructure power distribution.
• Manufacturing and process industry installations.
• Motor and inductive-load switching applications.
• Automated low-voltage distribution systems.
• Critical power and electrical infrastructure.
