Why Choose the ABB 1SDA112957R1 XT5 Withdrawable Fixed Part?
The ABB 1SDA112957R1 is a configurable withdrawable fixed part for ABB SACE Tmax XT5 circuit breakers, designed for low-voltage switchboards where withdrawable circuit-breaker functionality is required. Rated for 400 A and configured for three-pole installations, it forms the stationary chassis section of a compatible XT5 withdrawable circuit-breaker assembly.
ABB identifies this product as XT5 W FP 400A 3p frame configurable. The W FP designation refers to the withdrawable fixed part, which remains installed within the switchboard while the compatible moving circuit-breaker section can be withdrawn for inspection, maintenance or replacement. This architecture can simplify servicing while reducing the need to disturb permanent switchboard connections.
The configurable design allows the required terminal conversion kits to be selected separately according to the installation arrangement. With a 400 A rated uninterrupted current, three-pole construction and compatibility with the Tmax XT5 platform, the 1SDA112957R1 provides a manufacturer-engineered foundation for configurable withdrawable power-distribution assemblies.

Configurable Withdrawable Architecture for Tmax XT5
A withdrawable circuit-breaker system separates the stationary switchboard interface from the movable circuit-breaker section. The ABB 1SDA112957R1 forms the fixed part of this arrangement for compatible XT5 equipment, allowing the associated breaker section to be withdrawn while the fixed chassis remains installed within the electrical assembly.
The configurable version allows the required upper and lower terminal conversion arrangements to be selected according to the switchboard design. This modular approach gives panel builders greater flexibility when configuring conductor orientation and connection arrangements while maintaining compatibility with ABB's Tmax XT5 withdrawable architecture.
Typical Applications
- ABB Tmax XT5 withdrawable circuit-breaker assemblies.
- Industrial low-voltage switchboards.
- Main and sub-distribution panels.
- Commercial building power distribution.
- Manufacturing and process electrical systems.
- Switchboards requiring maintainable withdrawable circuit breakers.
- Panel-building projects requiring configurable XT5 connection arrangements.
