1SDA059676R1 ABB E4 W FP 3P VR-VR SACE Emax Fixed Part

Why Choose the ABB 1SDA059676R1 E4 W Fixed Part?

The ABB 1SDA059676R1 is a SACE Emax E4 fixed part designed for use with compatible withdrawable ABB E4 air circuit breakers. Identified by ABB as E4 W FP 3p VR-VR new, this fixed section forms the stationary part of a withdrawable circuit-breaker installation, providing the mechanical mounting and main-circuit connections required within low-voltage switchgear.

Designed for the ABB SACE Emax E4 frame, the 1SDA059676R1 features a three-pole configuration with vertical rear terminals at both the upper and lower connections. The VR-VR terminal arrangement is particularly useful where switchboard busbars and outgoing conductors are designed around vertically orientated rear connections.

The fixed part is intended to remain installed within the switchboard while a compatible withdrawable E4 circuit breaker can be inserted, isolated and removed as required. This modular arrangement supports efficient maintenance and replacement while helping minimise disruption to the surrounding switchgear installation.

Key Advantages

• Genuine ABB SACE Emax E4 fixed part for withdrawable circuit breakers.
• Three-pole configuration for three-phase power distribution systems.
• VR-VR vertical rear terminals at both upper and lower connections.
• Designed specifically for compatible E4 withdrawable circuit breakers.
• Fixed switchboard installation allows the circuit breaker moving part to be removed independently.
• Supports convenient circuit-breaker isolation, servicing and replacement.
• Robust construction for demanding industrial switchgear applications.
• Part of the established ABB SACE New Emax power distribution range.

Fixed Part for Withdrawable Emax Circuit Breaker Installations

Withdrawable air circuit-breaker systems separate the circuit breaker into a removable moving part and a permanently installed fixed part. The ABB 1SDA059676R1 provides the fixed interface for compatible E4 equipment, allowing the circuit-breaker moving part to be connected to or isolated from the main electrical circuit without dismantling the surrounding switchboard connections.

The VR-VR configuration provides vertical rear connections at both the upper and lower sides of the fixed part. This terminal arrangement enables switchboard designers to route busbars and conductors vertically behind the circuit breaker, supporting efficient integration into high-current industrial power distribution assemblies.

Typical Applications

• ABB SACE Emax E4 withdrawable circuit-breaker installations.
• Main low-voltage electrical distribution boards.
• Industrial switchboards and switchgear assemblies.
• Manufacturing and process plant power distribution.
• Commercial and industrial building distribution systems.
• Transformer and generator distribution switchboards.
• Infrastructure and utility electrical installations.
• Switchgear requiring removable and serviceable air circuit breakers.
