Why Choose the ABB 1SDA059775R1 E4/f Fixed Part?
The ABB 1SDA059775R1 is a genuine SACE Emax E4/f fixed part for four-pole withdrawable air circuit breaker installations. Identified as E4/f W FP 4p VR-VR new, it forms the stationary chassis of a compatible ABB E4/f withdrawable breaker assembly and provides the permanent interface between the switchboard and removable circuit breaker moving part.
This version is designed around the E4/f full-neutral configuration, providing a 100% neutral pole rather than the 50% fourth-pole arrangement used on standard E4 four-pole configurations. It is suitable for compatible E4/f applications with a rated uninterrupted current of up to 4000 A and a rated operational voltage of 690 V AC.
The 1SDA059775R1 uses a VR-VR terminal arrangement, with vertical rear connections at both the upper and lower main terminals. This arrangement supports high-current switchboard designs requiring vertically oriented rear busbar connections while retaining the serviceability advantages of a withdrawable circuit breaker system.

Full-Neutral Fixed Part for High-Current Emax Switchgear
Withdrawable air circuit breaker systems separate the permanent switchboard connections from the removable circuit breaker moving part. The ABB 1SDA059775R1 provides this stationary interface for the E4/f platform, allowing a compatible breaker to be withdrawn for servicing while the fixed main circuit connections remain installed.
The 100% neutral configuration provides a full-size fourth pole for applications where the neutral conductor requires the same current-carrying capability as the phase poles. Combined with vertical rear upper and lower connections, the E4/f fixed part provides a purpose-designed solution for demanding four-pole power distribution switchboards.
Typical Applications
- High-current low-voltage distribution switchboards.
- ABB SACE Emax E4/f withdrawable circuit breaker assemblies.
- Four-pole systems requiring a 100% neutral.
- Industrial power distribution systems.
- Commercial and infrastructure switchgear.
- Main incomer and high-current feeder installations.
- Switchboards requiring vertical rear main connections.

Frequently Asked Questions
What is the ABB 1SDA059775R1?
It is an ABB SACE Emax E4/f four-pole fixed part for a compatible withdrawable air circuit breaker, featuring a 100% neutral and vertical rear upper and lower terminals.
What does the 100% neutral specification mean?
The 100% neutral specification means the fourth or neutral pole is full size, providing the same current-carrying capability as the phase poles in the compatible E4/f configuration.
What current and voltage does the E4/f configuration support?
The compatible E4/f configuration supports a rated uninterrupted current of up to 4000 A and a rated voltage of 690 V AC.
What does the VR-VR terminal configuration mean?
The VR-VR configuration means both the upper and lower main terminals use a vertical rear orientation for connection to compatible switchboard busbars.
Is the ABB 1SDA059775R1 a complete circuit breaker?
No. It is the fixed part or chassis of an ABB SACE Emax E4/f withdrawable circuit breaker assembly and requires a compatible E4/f moving part to form the complete breaker installation.
Trusted ABB Power Distribution Technology
ABB SACE Emax fixed parts provide robust permanent switchboard interfaces for withdrawable air circuit breaker systems, supporting high-current four-pole distribution with full-neutral configurations and practical circuit breaker maintenance.
