Why Choose the ABB XT4 W FP 3p HR Fixed Part?
The ABB XT4 W FP 3p HR, order code 1SDA068205R1, is a three-pole fixed part for withdrawable ABB SACE Tmax XT4 circuit breakers. Part of the ABB Tmax XT range, it provides the stationary electrical and mechanical interface required when configuring a compatible XT4 circuit breaker in a withdrawable installation.
The withdrawable arrangement is designed to support convenient installation, extraction and maintenance of compatible Tmax XT4 circuit breakers. The fixed part remains installed and connected within the switchboard while the appropriately configured moving circuit breaker can be withdrawn, helping simplify servicing and replacement in applications where maintainability and continuity are important considerations.
The 1SDA068205R1 has a three-pole configuration, a rated uninterrupted current of 250 A and horizontal rear terminals, identified by the HR designation. It supports rated operational voltages up to 690 V AC and 500 V DC and is specifically designed for compatible ABB Tmax XT4 withdrawable circuit breaker assemblies.

Flexible Withdrawable Installation for Tmax XT4 Circuit Breakers
A withdrawable circuit breaker arrangement uses a fixed part connected to the electrical installation together with a compatible moving circuit breaker assembly. The ABB XT4 W FP 3p HR provides this stationary interface, enabling an appropriately configured XT4 circuit breaker to be inserted or withdrawn while the fixed section and its principal switchboard connections remain installed.
The horizontal rear terminals are particularly suited to switchboard designs requiring connections behind the breaker position. Combined with a rated uninterrupted current of 250 A, operational voltage capability up to 690 V AC and the modular Tmax XT4 platform, the 1SDA068205R1 provides a practical solution for maintainable industrial and commercial power-distribution assemblies.
Typical Applications
- Industrial low-voltage distribution boards.
- Main and sub-distribution switchboards.
- Three-phase electrical distribution systems.
- Withdrawable ABB Tmax XT4 circuit breaker installations.
- Electrical panels requiring horizontal rear connections.
- Industrial machinery power-distribution systems.
- Commercial building electrical distribution.
- Infrastructure and utility distribution panels.
- OEM switchgear and control-panel assemblies.
