Why Choose the ABB 1SDA104688R1 XT5 Withdrawable Fixed Part?
The ABB 1SDA104688R1 is a fixed part for a withdrawable ABB SACE Tmax XT5 circuit breaker, designed for compatible 400 A four-pole XT5 installations. Identified as XT5 W FP 400A 4p HR HR IEC, it forms the stationary section of the withdrawable assembly and provides the mechanical and electrical interface for the compatible moving part.
The fixed part has a 400 A rated uninterrupted current and a 690 V AC rated operational voltage at 50/60 Hz. Its four-pole construction supports compatible four-pole distribution systems, while the withdrawable architecture allows the associated circuit breaker to be disconnected and removed while the fixed portion remains installed in the switchboard.
The 1SDA104688R1 is supplied with rear horizontal terminals (HR), providing rear-facing main-circuit connections for switchboard layouts where conductors or busbars are routed behind the breaker assembly. Designed for IEC applications, the fixed part complies with IEC 60947-2 and is purpose-built for the ABB SACE Tmax XT5 platform.

Withdrawable Circuit-Breaker Installation with Rear Connections
A withdrawable circuit-breaker system separates the installation into a stationary fixed part and a removable moving part containing the circuit breaker. This arrangement enables the compatible breaker to be disconnected and withdrawn from the switchboard while the fixed section and its main electrical connections remain installed, helping simplify inspection, maintenance and equipment replacement.
The ABB 1SDA104688R1 provides this fixed interface for compatible XT5 400 A four-pole circuit breakers. Its rear horizontal terminals are factory-oriented for connections behind the breaker assembly, making the unit particularly suitable for switchboard designs using rear busbar or conductor routing.
Typical Applications
- ABB SACE Tmax XT5 withdrawable circuit-breaker installations.
- Industrial low-voltage switchboards.
- Commercial power distribution panels.
- Four-pole 400 A distribution circuits.
- Switchboards using rear busbar or conductor connections.
- Electrical systems requiring removable circuit breakers for maintenance.
- IEC-compliant low-voltage power distribution assemblies.
