Why Choose the ABB T5S 400 Breaking Part 3P FF?
The ABB T5S 400 Breaking Part 3P FF, order code 1SDA054578R1, 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 T5S 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. This modular arrangement allows compatible ABB Tmax T5 trip units and accessories to be selected according to the protection and installation requirements of the electrical system, while the T5S breaking unit provides the switching and fault-interruption platform.
The 1SDA054578R1 features a 400 A frame rating, three-pole configuration, fixed construction and front terminals. The T5S performance level is intended for industrial power distribution applications requiring greater short-circuit interruption capability than the standard T5N version, making it suitable for switchboards and distribution systems with elevated prospective fault currents.
Key Advantages
- Genuine ABB SACE Tmax T5S 400 breaking part for compatible MCCB assemblies.

High-Performance Breaking Unit for Tmax T5 Assemblies
The breaking part forms the principal current-carrying and fault-interruption section of a moulded case circuit breaker. When combined with a compatible ABB protection unit, the T5S 400 breaking unit provides the physical switching and interruption platform required to disconnect fault currents and protect industrial electrical distribution systems.
The modular Tmax T5 design allows the protection characteristics of the finished circuit breaker to be selected separately from the breaking unit. This makes the 400 A T5S platform suitable for switchboard builders, OEMs and industrial installations requiring a configurable ABB circuit protection solution with a fixed three-pole arrangement and front-connected main terminals.
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.
- Installations with elevated prospective short-circuit currents.
- Commercial and infrastructure power distribution.
- OEM switchboards and electrical distribution assemblies.
