Reliable Fixed-Part Interface for DC Emax Switchgear
A fixed part forms the stationary section of a withdrawable air circuit breaker installation, providing the mechanical and electrical interface between the breaker moving part and the switchboard. This architecture allows the compatible breaker to be withdrawn for inspection, maintenance or replacement while the fixed assembly and its main electrical connections remain installed.
The ABB 1SDA059890R1 is specifically configured for 750 V DC applications and combines the E1/E frame with a 3-pole arrangement and horizontal rear terminals at both ends. Its 1600 A rated uninterrupted current supports substantial DC distribution duties where maintainability and rear-connected switchgear integration are required.
Typical Applications
- Industrial 750 V DC power distribution systems.
- DC low-voltage switchboards and distribution assemblies.
- Withdrawable ABB SACE Emax E1/E circuit breaker installations.
- High-current DC distribution and isolation systems.
- Industrial, infrastructure and process power installations.
- Switchgear refurbishment, maintenance and lifecycle replacement projects.
