1SDA059823R1 ABB E4/f W FP 4p VR-HR Fixed Part 4000 A

Why Choose the ABB 1SDA059823R1 E4/f W FP 4p VR-HR Fixed Part?

The ABB 1SDA059823R1 is a heavy-duty SACE Emax E4/f fixed part for a withdrawable air circuit breaker, designed for high-current low-voltage power distribution and industrial switchboard applications. Identified by ABB as E4/f W FP 4p VR-HR new, it provides the stationary electrical and mechanical interface required for a compatible four-pole Emax E4/f withdrawable circuit breaker.

As part of the established ABB SACE Emax series, this fixed part is engineered for switchgear installations where high current capacity, dependable power distribution and straightforward circuit-breaker maintenance are essential. The fixed part remains installed within the switchboard while the compatible withdrawable E4/f circuit breaker can be inserted, isolated or removed for inspection, servicing and replacement.

With a rated uninterrupted current of 4000 A and a rated voltage of 690 V AC, the 1SDA059823R1 is suitable for demanding industrial distribution systems. Its four-pole / f configuration uses vertical rear upper terminals and horizontal rear lower terminals (VR-HR), providing a versatile connection arrangement for engineered high-current switchboards.

Reliable High-Current Circuit Breaker Integration

A fixed part forms the stationary section of a withdrawable air circuit-breaker installation. It remains mounted within the electrical switchboard and provides the electrical and mechanical interface for the compatible withdrawable breaker, allowing the circuit breaker to be removed for inspection, servicing or replacement without dismantling the principal switchboard connections.

The ABB 1SDA059823R1 is specifically configured for the Emax E4/f platform and combines a substantial 4000 A current rating with a mixed VR-HR rear terminal arrangement. The vertical rear upper terminals and horizontal rear lower terminals provide flexibility when designing busbar connections and integrating the fixed part into high-current low-voltage switchboards.

Typical Applications

• High-current industrial low-voltage switchboards.
• Main power distribution systems.
• Withdrawable air circuit-breaker installations.
• Industrial distribution and switchgear panels.
• Manufacturing and process plants.
• Commercial and infrastructure power distribution systems.
