1SDA059694R1 ABB E4 W FP 3P HR-VR New Fixed Part 4000 A 690 V

Why Choose the ABB E4 W FP 3P HR-VR New Fixed Part?

The ABB E4 W FP 3P HR-VR new, order code 1SDA059694R1, is a heavy-duty SACE Emax E4 fixed part for withdrawable air circuit breakers designed for high-current industrial power distribution systems. As part of the ABB New Emax family, it provides the permanently installed mechanical and electrical interface required for a compatible withdrawable E4 circuit breaker within low-voltage switchgear.

This version features a three-pole configuration with an HR-VR terminal arrangement: horizontal rear terminals at the upper connection and vertical rear terminals at the lower connection. This mixed terminal orientation provides flexibility when engineering busbar connections and integrating the fixed part into complex switchboard layouts.

With a rated uninterrupted current of 4000 A and a rated voltage of 690 V AC, the 1SDA059694R1 is engineered for demanding high-power distribution duties. The fixed part is also listed in ABB's Emax ordering data as a three-pole E4 HR-VR configuration for applications up to 750 V DC, making it a versatile platform for specialised power distribution installations.

Reliable High-Current Circuit Breaker Integration

A fixed part forms the permanently installed section of a withdrawable air circuit breaker assembly, providing the electrical connections and mechanical interface between the removable breaker and the switchboard. This architecture allows a compatible E4 circuit breaker to be withdrawn for inspection, maintenance or replacement while the fixed part remains installed in the electrical distribution assembly.

The ABB 1SDA059694R1 combines a substantial 4000 A current capability with a flexible HR-VR terminal arrangement. Horizontal rear upper terminals and vertical rear lower terminals can accommodate specific busbar layouts, making this fixed part particularly useful in engineered high-current switchboards where connection geometry and serviceability are important.

Typical Applications

• High-current industrial low-voltage switchboards.
• Main incoming and power distribution assemblies.
• Three-phase industrial distribution systems.
• Withdrawable air circuit breaker installations.
• Manufacturing and process plant electrical systems.
• Infrastructure and utility distribution equipment.
• OEM switchgear and engineered panel-building applications.
