Reliable Switching and Isolation for Power Distribution
Switch disconnectors provide controlled switching and isolation of electrical circuits without incorporating the overcurrent protection functions of a conventional circuit breaker. The ABB E1B/MS is therefore suited to installations where circuit protection is provided separately and a robust switching device is required for operational isolation, maintenance and segregation of distribution circuits.
The SACE Emax platform is engineered for demanding low-voltage switchboards and industrial power distribution. With its 800 A rating, three-pole fixed construction, rear horizontal connections and substantial short-time withstand capability, the E1B/MS 800 provides a dependable solution for industrial and commercial electrical distribution assemblies.
Typical Applications
- Industrial low-voltage power distribution switchboards.
- Main incoming and distribution isolation.
- Electrical switchgear and control assemblies.
- Industrial plants and manufacturing facilities.
- Commercial and infrastructure power distribution.
- Feeder and busbar isolation.
