Why Choose the ABB 1SDA059766R1 E4 Fixed Part?
The ABB 1SDA059766R1 is a genuine SACE Emax E4 fixed part designed for four-pole withdrawable air circuit breaker installations. Identified as E4 W FP 4p HR-HR new, it forms the stationary section of a compatible ABB E4 withdrawable circuit breaker assembly and provides the permanent interface between the breaker moving part and the switchboard.
This E4 fixed part is intended for demanding low-voltage power distribution systems where withdrawable circuit breaker construction supports straightforward inspection, servicing and replacement. The compatible breaker moving part can be withdrawn while the fixed part remains installed and connected to the switchboard.
The 1SDA059766R1 has a four-pole configuration with horizontal rear terminals on both the upper and lower connections. ABB identifies this HR version within the E4 withdrawable fixed-part range, with the fourth pole specified at 50% for this configuration.

Reliable Fixed Part for Emax Withdrawable Switchgear
A withdrawable air circuit breaker installation separates the permanent switchboard connections from the removable circuit breaker moving part. The ABB 1SDA059766R1 provides the fixed portion of this arrangement for the E4 frame, allowing the compatible breaker to be withdrawn without dismantling the main switchboard connections.
The HR-HR configuration provides horizontal rear connections at both the upper and lower terminals, making the fixed part suitable for switchboard designs using corresponding rear busbar arrangements. Its four-pole construction also supports systems requiring switching across four conductors.
Typical Applications
- Low-voltage main distribution switchboards.
- ABB SACE Emax E4 withdrawable circuit breaker assemblies.
- Industrial power distribution systems.
- Commercial and infrastructure switchgear.
- Main incomer and high-current feeder installations.
- Four-pole distribution systems requiring horizontal rear connections.
