1SDA059788R1 ABB E2S W FP 4P FL-FL SACE Emax Fixed Part 2000 A

Why Choose the ABB 1SDA059788R1 E2S W Fixed Part?

The ABB 1SDA059788R1 is a SACE Emax E2S fixed part designed for use with compatible withdrawable ABB E2S air circuit breakers. Identified by ABB as E2S W FP 4p FL-FL new, this four-pole fixed section forms the stationary component of a withdrawable circuit-breaker installation, providing the mechanical interface and main power connections required within low-voltage switchgear.

Designed for the ABB SACE Emax E2S frame, the 1SDA059788R1 has a rated uninterrupted current of 2000 A and a rated voltage of 690 V AC. Its four-pole configuration supports three-phase four-wire distribution systems, while the FL-FL arrangement provides flat terminals at both the upper and lower main connections.

The fixed part remains installed within the switchboard while a compatible withdrawable E2S circuit-breaker moving part can be inserted, isolated and removed as required. This modular arrangement supports efficient maintenance and circuit-breaker replacement while retaining the fixed power connections within the switchgear assembly.

Key Advantages

• Genuine ABB SACE Emax E2S fixed part for withdrawable air circuit breakers.
• 2000 A rated uninterrupted current for high-current power distribution.
• Four-pole configuration for three-phase four-wire electrical systems.
• 690 V AC rated voltage for industrial low-voltage distribution applications.
• FL-FL flat terminal arrangement at both upper and lower main connections.
• Designed specifically for compatible E2S withdrawable circuit-breaker moving parts.
• Fixed switchboard installation allows the breaker moving part to be isolated and removed independently.
• Robust ABB construction for industrial, commercial and infrastructure switchgear installations.

Flat-Terminal Fixed Part for Withdrawable Emax Installations

Withdrawable air circuit-breaker systems separate the assembly into a removable circuit-breaker moving part and a permanently installed fixed part. The ABB 1SDA059788R1 provides the stationary interface for compatible E2S equipment, allowing the circuit breaker to be connected to, isolated from and removed from the electrical system while the principal switchboard connections remain in position.

The FL-FL terminal configuration provides flat upper and lower main terminals for integration with the corresponding switchboard conductor arrangement. Combined with its 2000 A rated uninterrupted current and four-pole construction, the E2S fixed part is suited to substantial three-phase four-wire distribution systems requiring a serviceable withdrawable circuit-breaker architecture.

Typical Applications

• ABB SACE Emax E2S withdrawable circuit-breaker installations.
• Main low-voltage electrical distribution boards.
• Industrial switchboards and switchgear assemblies.
• Three-phase four-wire power distribution systems.
• Manufacturing and process plant power distribution.
• Commercial and industrial building distribution systems.
• Transformer and generator distribution switchboards.
• Switchgear requiring removable and serviceable air circuit breakers.
