Why Choose the ABB 1SDA059778R1 E1 W FP 4p F-F Fixed Part?
The ABB 1SDA059778R1, identified as E1WFP4pF-Fnew, is a four-pole fixed part for a withdrawable SACE Emax E1 air circuit-breaker. Designed for ABB’s SACE Emax low-voltage power circuit-breaker system, it provides the stationary chassis and electrical connection interface required for installation of a compatible E1 withdrawable circuit-breaker moving part.
This fixed part uses an F-F front terminal configuration, with both the upper and lower main-circuit connections arranged for front connection. This configuration supports practical integration into switchboards where front-accessible busbar or conductor connections are required, while retaining the serviceability benefits of a withdrawable air circuit-breaker system.
With a 4-pole configuration, 1600 A rated uninterrupted current and 690 V AC rated voltage, the 1SDA059778R1 is designed for substantial low-voltage power-distribution applications. The fixed part remains installed within the switchboard while the compatible E1 circuit-breaker moving portion can be inserted or withdrawn for operation, inspection and maintenance.

Reliable Fixed Connection for Emax E1 Switchgear
A withdrawable air circuit-breaker system separates the permanently installed fixed part from the removable circuit-breaker moving portion. The ABB 1SDA059778R1 remains secured within the switchboard and provides the stationary mechanical and electrical interface for a compatible SACE Emax E1 breaker, allowing the moving portion to be withdrawn without dismantling the principal switchboard connections.
The F-F configuration provides front-facing upper and lower main-circuit connections, making the fixed part suitable for switchboard designs based around front terminal access. Combined with the E1 frame’s 1600 A current capability, this arrangement provides a robust foundation for dependable low-voltage power distribution in industrial, commercial and infrastructure installations.
Typical Applications
- Low-voltage main distribution switchboards.
- Industrial power-distribution systems.
- ABB SACE Emax E1 withdrawable circuit-breaker installations.
- Four-pole power distribution assemblies.
- Manufacturing and process-industry switchgear.
- Commercial building and infrastructure electrical distribution.
- Switchboards requiring upper and lower front main-circuit connections.
