Why Choose the ABB 1SDA104703R1 XT7-XT7M Withdrawable Fixed Part?
The ABB 1SDA104703R1 is a three-pole fixed part for withdrawable ABB SACE Tmax XT7 and XT7M circuit breakers. Identified as XT7-XT7M W FP 3p HR IEC/UL, it forms the stationary section of a withdrawable circuit-breaker assembly and provides the mechanical and electrical interface required for a compatible XT7 or XT7M moving part.
The fixed part has a 1600 A rated uninterrupted current and is designed for high-current low-voltage power distribution applications. Its withdrawable architecture allows a compatible circuit breaker to be disconnected and removed for inspection, servicing or replacement while the fixed part and its main switchboard connections remain installed.
The 1SDA104703R1 is supplied with rear horizontal terminals (HR), providing rear-facing main-circuit connections suited to switchboards where conductors or busbars are routed behind the breaker assembly. Designed for both IEC and UL applications, the fixed part is specified for IEC 60947-2 and UL 489 installations.
Key Advantages
- Purpose-designed fixed part for ABB SACE Tmax XT7 and XT7M withdrawable circuit breakers.

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 This arrangement enables the compatible breaker to be disconnected and withdrawn while the fixed section and its main electrical connections remain installed, helping simplify inspection, maintenance and circuit-breaker replacement.
The ABB 1SDA104703R1 provides this fixed interface for compatible XT7 and XT7M three-pole circuit breakers. Its rear horizontal terminals provide rear-facing main-circuit connections, making the unit particularly suitable for switchboard designs where busbars or conductors are routed behind the circuit-breaker assembly.
Typical Applications
- ABB SACE Tmax XT7 withdrawable circuit-breaker installations.
- ABB SACE Tmax XT7M withdrawable circuit-breaker installations.
- Industrial low-voltage switchboards.
- High-current power distribution panels.
- Three-pole power distribution circuits.
- Switchboards using rear busbar or conductor connections.
- Electrical systems requiring removable circuit breakers for maintenance.
- IEC 60947-2 and UL 489 low-voltage distribution assemblies.
