1SDA059769R1 ABB E6/f W FP 4p HR-HR New Fixed Part 6300 A 690 V

Why Choose the ABB E6/f W FP 4p HR-HR New Fixed Part?

The ABB E6/f W FP 4p HR-HR new, order code 1SDA059769R1, is a heavy-duty SACE Emax E6/f fixed part for withdrawable air circuit breakers designed for very high-current industrial low-voltage power distribution systems. As part of the ABB New Emax family, it provides the permanently installed mechanical and electrical interface required for a compatible full-size four-pole E6/f withdrawable circuit breaker.

This fixed part features a four-pole full-size configuration with horizontal rear terminals at both the upper and lower connections. Unlike the standard E6 four-pole arrangement with a reduced fourth pole, the E6/f configuration uses a full-size fourth pole, making it suitable for installations requiring full current capability across all four poles.

With a rated uninterrupted current of 6300 A and a rated voltage of 690 V AC, the 1SDA059769R1 is engineered for exceptionally demanding power distribution duties. Its withdrawable architecture, substantial E6/f frame and HR-HR connection arrangement make it well suited to main switchboards and engineered distribution systems where high current capacity, neutral switching and serviceability are essential.

Key Advantages

• Genuine ABB SACE Emax E6/f fixed part for compatible withdrawable air circuit breakers.
• 6300 A rated uninterrupted current for very high-current power distribution.
• 690 V AC rated voltage for demanding industrial low-voltage systems.
• Four-pole full-size configuration for applications requiring full-capacity neutral switching.
• Upper and lower horizontal rear terminals suit horizontal busbar arrangements.
• Withdrawable architecture facilitates circuit breaker inspection, maintenance and replacement.

Key Features

• ABB SACE Emax / New Emax E6/f series.
• WFP fixed-part version.
• 4-pole full-size (4/f) configuration.
• 6300 A rated uninterrupted current (Iu).
• 690 V AC rated voltage (Ur).
• Horizontal rear upper terminals (HR).
• Horizontal rear lower terminals (HR).
• Designed for compatible withdrawable E6/f air circuit breakers.
• Heavy-duty construction for high-capacity industrial switchgear.
• Designed in accordance with applicable IEC requirements.

Reliable High-Current Circuit Breaker Integration

A fixed part forms the permanently installed section of a withdrawable air circuit breaker assembly, providing the mechanical mounting and electrical connections between the removable breaker and the switchboard. This arrangement enables a compatible E6/f circuit breaker to be withdrawn for inspection, maintenance or replacement while the fixed assembly remains installed in the switchgear.

The ABB 1SDA059769R1 combines an exceptional 6300 A current capability with a full-size four-pole design and horizontal rear connections. This configuration is particularly suited to high-capacity distribution systems where the neutral pole requires full-size construction and the switchboard busbar architecture favours rear horizontal connections.

Typical Applications

• Very high-current industrial low-voltage switchboards.
• Main incoming and power distribution assemblies.
• Four-pole three-phase systems requiring full-size neutral switching.
• Withdrawable air circuit breaker installations.
• Manufacturing and process plant electrical distribution.
• Infrastructure and utility power distribution systems.
• OEM switchgear and engineered panel-building applications.
