Why Choose the ABB XT2 W FP 4p HR Fixed Part?
The ABB 1SDA068203R1 XT2 W FP 4p HR is a four-pole fixed part for withdrawable ABB SACE Tmax XT2 moulded case circuit breakers. Designed as the stationary section of an XT2 withdrawable installation, it provides the permanent electrical and mechanical interface required for a compatible withdrawable breaker assembly while supporting convenient removal for inspection, servicing or replacement.
Rated for an uninterrupted current of 160 A, the fixed part supports rated operational voltages up to 690 V AC and 500 V DC. The HR configuration uses horizontal rear terminals, enabling the main circuit connections to be routed behind the breaker assembly and helping create an organised switchboard layout with permanent fixed-side connections.
The withdrawable arrangement enables a suitably configured XT2 moving part to be withdrawn from the fixed section without dismantling the permanent main-circuit connections. With its four-pole configuration, 1000 V insulation voltage and 8 kV impulse withstand voltage, the 1SDA068203R1 provides a robust connection platform for three-phase and neutral industrial and commercial distribution systems.
Key Advantages
- Genuine ABB SACE Tmax XT2 withdrawable fixed part.
- 160 A rated uninterrupted current for compatible XT2 installations.
- Four-pole configuration for three-phase and neutral electrical systems.
- Horizontal rear terminals support convenient rear conductor or busbar connection.

Flexible Withdrawable Connection for Tmax XT2 Circuit Breakers
The ABB XT2 W FP fixed part forms the stationary section of a withdrawable Tmax XT2 circuit breaker installation. Once mounted and connected within the switchboard, it provides the fixed interface required for the compatible withdrawable breaker assembly. This arrangement is particularly useful where maintainability and rapid replacement are important because permanent switchboard-side connections do not need to be dismantled each time the compatible breaker moving part is removed.
The HR horizontal rear terminal arrangement directs the main electrical connections towards the rear of the assembly, making the 1SDA068203R1 suitable for switchboards using rear busbars or conductors. The fixed part itself does not provide overcurrent protection; protection and short-circuit interruption characteristics depend on the compatible ABB SACE Tmax XT2 breaker and trip unit incorporated into the completed assembly.
Typical Applications
- ABB Tmax XT2 withdrawable circuit breaker assemblies.
- Industrial low-voltage switchboards.
- Main and sub-distribution panels.
- Three-phase and neutral electrical distribution systems.
- Manufacturing and production facilities.
- Commercial electrical distribution boards.
- Machinery and automation power distribution.
- Switchboards requiring removable breakers with permanent fixed-side connections.
