1SDA059768R1 ABB E6 W FP 4p HR-HR New Fixed Part 6300 A 690 V

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

The ABB E6 W FP 4p HR-HR new, order code 1SDA059768R1, is a heavy-duty SACE Emax E6 fixed part for withdrawable air circuit breakers designed for very high-current industrial low-voltage power distribution systems. Also identified as NEW E6 FP 4P RHT, it provides the permanently installed mechanical and electrical interface required for a compatible withdrawable E6 circuit breaker within switchgear and distribution assemblies.

This version features a four-pole configuration with horizontal rear terminals at both the upper and lower connections. The HR-HR arrangement is well suited to horizontal busbar layouts, while the withdrawable architecture allows the compatible circuit breaker to be removed for inspection, servicing or replacement without removing the fixed part from the switchboard.

With a rated uninterrupted current of 6300 A and a rated voltage of 690 V AC, the 1SDA059768R1 is engineered for exceptionally demanding power distribution duties. Its four-pole E6 construction, IEC design and substantial SACE Emax format make it suitable for main switchboards, industrial plants, infrastructure and engineered distribution systems requiring high current capacity and neutral switching.

Key Advantages

• Genuine ABB SACE Emax E6 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 configuration for three-phase systems requiring a switched neutral pole.
• Upper and lower horizontal rear terminals suit horizontal busbar connection arrangements.
• Withdrawable architecture supports efficient circuit breaker inspection, maintenance and replacement.

Key Features

• ABB SACE Emax / New Emax E6 series.
• WFP fixed-part version.
• 4-pole configuration.
• 6300 A rated uninterrupted current (Iu).
• 690 V AC rated voltage (Ur).

• Horizontal rear lower terminals (HR).
• Designed for withdrawable E6 air circuit breakers.
• Robust fixed-part construction for high-capacity 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 support and electrical connections between the removable breaker and the switchboard. This arrangement enables a compatible E6 circuit breaker to be withdrawn for inspection, servicing or replacement while the fixed assembly remains installed in the switchgear.

The ABB 1SDA059768R1 combines an exceptional 6300 A current capability with four-pole construction and horizontal rear upper and lower connections. This combination is particularly suited to high-capacity distribution systems where a neutral pole is required and the switchboard busbar architecture favours rear horizontal connections.

Typical Applications

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