1SDA059777R1 ABB E6/f W FP 4P VR-VR SACE Emax Fixed Part 6300 A

Why Choose the ABB 1SDA059777R1 E6/f W Fixed Part?

The ABB 1SDA059777R1 is a SACE Emax E6/f fixed part designed for use with compatible withdrawable ABB E6/f air circuit breakers. Identified by ABB as E6/f W FP 4p VR-VR new, this four-pole, full-size-neutral fixed section forms the stationary component of a withdrawable circuit-breaker installation, providing the mechanical interface and main power connections required within high-current low-voltage switchgear.

Designed for the ABB SACE Emax E6/f frame, the 1SDA059777R1 has a rated uninterrupted current of 6300 A and a rated voltage of 690 V AC. Its four-pole full-size configuration is intended for applications requiring a full-size fourth pole, while the VR-VR arrangement provides rear flat vertical connections for integration with suitably configured switchboard busbars.

The fixed part remains installed within the switchboard while a compatible withdrawable E6/f circuit-breaker moving part can be inserted, isolated and removed as required. This modular architecture supports efficient servicing and breaker replacement while retaining the principal high-current power connections within the switchgear assembly.

Key Advantages

• Genuine ABB SACE Emax E6/f fixed part for withdrawable air circuit breakers.
• 6300 A rated uninterrupted current for demanding high-current power distribution.
• Four-pole full-size configuration for applications requiring a full-size fourth pole.
• 690 V AC rated voltage for industrial low-voltage distribution systems.
• VR-VR rear flat vertical terminal arrangement for vertical switchboard busbar connections.
• Designed specifically for compatible E6/f withdrawable circuit-breaker moving parts.
• Fixed switchboard installation allows the breaker moving section to be isolated and removed independently.
• Heavy-duty construction for large industrial, infrastructure and power distribution installations.

Full-Size Four-Pole Fixed Part for High-Current Emax Installations

The E6/f designation identifies an E6 configuration with a full-size fourth pole, providing a four-pole architecture for applications where the fourth conductor requires the full current-carrying capability of the main poles. The ABB 1SDA059777R1 provides the stationary fixed interface for the corresponding withdrawable E6/f circuit-breaker moving section.

Its VR-VR rear flat vertical terminal configuration supports vertical busbar connections within the switchboard, while the 6300 A rated uninterrupted current makes the assembly suitable for substantial power distribution duties. The withdrawable architecture enables the compatible breaker moving part to be isolated and removed while the fixed section and principal switchboard connections remain installed.

Typical Applications

• ABB SACE Emax E6/f withdrawable circuit-breaker installations.
• High-current main low-voltage distribution switchboards.
• Four-pole systems requiring a full-size fourth pole.
• Industrial main incomer and bus-coupler switchgear.
• Manufacturing and process plant power distribution.
• Transformer secondary distribution systems.
• Generator and standby power distribution switchboards.
• Infrastructure, utility and large commercial electrical installations.
