Why Choose the ABB 1SDA062049R1 T7-X1 Withdrawable Fixed Part?
The ABB 1SDA062049R1 is a T7-X1 withdrawable circuit breaker fixed part designed for compatible ABB Tmax T7, T7M and Emax X1 installations. Identified as T7-X1 W FP 4p EF-EF, it provides the stationary chassis and electrical connection interface required for a compatible withdrawable circuit breaker assembly.
This fixed part is configured for a four-pole circuit breaker and has a rated uninterrupted current of 1600 A. The EF-EF extended front terminal configuration provides front-accessible main-circuit connections on both sides, making it particularly useful where the switchboard design requires extended front terminals rather than rear-connected conductors.
Rated for operation at up to 690 V AC, the 1SDA062049R1 combines a substantial fixed chassis with the flexibility of ABB's withdrawable breaker architecture. The compatible moving part can be connected, isolated and withdrawn while the fixed part remains installed in the switchboard, supporting maintainability and efficient equipment replacement.
Key Advantages
- Genuine ABB T7-X1 withdrawable fixed part.
- High 1600 A rated uninterrupted current.
- Four-pole construction for compatible T7-X1 assemblies.
- EF-EF extended front terminals for accessible main-circuit connections.
- Withdrawable architecture supports easier circuit breaker isolation, servicing and replacement.
- Rated for low-voltage distribution systems up to 690 V AC.
Key Features
- ABB T7-X1 W FP 4p EF-EF fixed part.
- Designed for withdrawable circuit breaker installations.
- 1600 A rated uninterrupted current (Iu).
- Four-pole configuration.
- 690 V AC rated operational voltage.
- EF-EF extended front terminal arrangement.

- ABB order code 1SDA062049R1.
Extended Front Connections for Withdrawable Circuit Breakers
A withdrawable circuit breaker system separates the installation into a stationary fixed part and a removable moving part. The fixed part remains mounted in the switchboard and provides the mechanical support and main electrical interface, while the compatible circuit breaker can be withdrawn when isolation, inspection, servicing or replacement is required.
The ABB 1SDA062049R1 provides this stationary interface for a four-pole T7-X1 arrangement rated at 1600 A. Its EF-EF extended front terminals bring the main connections towards the front of the fixed part, providing an alternative connection arrangement to T7-X1 versions equipped with rear horizontal terminals.
Typical Applications
- ABB Tmax T7 and T7M withdrawable circuit breaker installations.
- Compatible ABB Emax X1 switchboard configurations.
- Industrial low-voltage power distribution.
- Main incoming and outgoing switchboard feeders.
- Four-pole high-current distribution systems.
- Switchboards requiring withdrawable breakers with extended front connections.
