Why Choose the ABB T5 400 W FP 4p EF Fixed Part?
The ABB T5 400 W FP 4p EF, order code 1SDA054758R1, is a 400 A four-pole fixed part for withdrawable ABB SACE Tmax T5 moulded-case circuit breakers. It forms the stationary section of a compatible withdrawable T5 400 installation, providing the fixed mechanical and electrical interface while allowing the circuit breaker moving part to be removed when required.
This version features extended front terminals, identified by the ABB designation EF. The extended front-terminal configuration provides accessible front-facing power connections for integration with conductors or busbars, making it suitable for switchboard designs where front connection is preferred over rear horizontal or vertical terminals.
With a rated uninterrupted current of 400 A, a four-pole configuration and rated operational voltages up to 690 V AC and 750 V DC, the T5 400 W FP 4p EF provides a purpose-designed fixed base for compatible ABB SACE Tmax T5 400 withdrawable circuit breakers in industrial and commercial distribution systems.

Withdrawable Circuit Breaker Integration for Distribution Systems
A withdrawable circuit breaker arrangement separates the removable breaker moving part from the stationary power-connection assembly. The ABB T5 400 W FP 4p EF remains installed within the switchboard and provides the fixed interface for a compatible Tmax T5 400 withdrawable breaker, supporting convenient breaker removal, servicing and replacement.
Its extended front terminals provide an accessible connection point for conductors or busbars at the front of the fixed part. Combined with its 400 A current rating and four-pole construction, this makes the unit suitable for engineered distribution assemblies requiring a maintainable withdrawable circuit breaker arrangement with front power connections.
Typical Applications
- Industrial low-voltage distribution switchboards.
- Commercial power distribution panels.
- Withdrawable ABB SACE Tmax T5 400 circuit breaker assemblies.
- Main and sub-distribution boards.
- Switchboards requiring extended front conductor or busbar connections.
- AC and DC distribution installations using compatible Tmax T5 400 circuit breakers.
