Why Choose the ABB T5N 400 Breaking Part 3P FF?
The ABB T5N 400 Breaking Part 3P FF, order code 1SDA054577R1, is a fixed three-pole breaking unit designed for use within ABB SACE Tmax T5 moulded case circuit breaker assemblies. As part of the ABB SACE Tmax T5 series, it provides the main current-carrying and fault-interruption section required to configure a T5N 400 circuit breaker with compatible ABB protection and operating components.
This product is supplied as a breaking part rather than a complete circuit breaker with protection unit. Its modular design allows the appropriate compatible ABB trip unit and accessories to be selected for the protection requirements of the installation, while the T5N breaking unit provides the switching and short-circuit interruption platform.
The 1SDA054577R1 features a 400 A rated uninterrupted current, three-pole configuration, fixed construction and front terminals. The T5N 400 platform has an ultimate short-circuit breaking capacity of 36 kA at 400 V AC, 50 Hz and a rated voltage of 690 V AC, making it suitable for a broad range of industrial power distribution applications.

Reliable Breaking Performance for Tmax T5 Assemblies
The breaking part forms the principal current-carrying and fault-interruption section of a moulded case circuit breaker. In a correctly configured ABB Tmax T5 assembly, it works with the selected compatible protection unit to interrupt fault currents and provide the switching platform required for industrial electrical distribution.
The T5N 400 platform combines a 400 A rated uninterrupted current with a 36 kA ultimate breaking capacity at 400 V AC. Its fixed three-pole design and front terminals make the 1SDA054577R1 particularly suitable for integration into industrial switchboards, distribution panels and OEM power assemblies where a modular ABB Tmax solution is required.
Typical Applications
- ABB SACE Tmax T5 moulded case circuit breaker assemblies.
- Industrial electrical power distribution systems.
- Electrical switchboards and distribution panels.
- Three-phase industrial feeder circuits.
- Industrial machinery electrical distribution.
- Commercial and infrastructure power distribution.
- Power generation and energy installations.
- OEM switchboards and electrical distribution assemblies.
