Why Choose the ABB T4V 250 Breaking Part 4P FF?
The ABB T4V 250 Breaking Part 4P FF, order code 1SDA054566R1, is a high-performance four-pole breaking unit designed for use within ABB SACE Tmax T4 moulded case circuit breaker assemblies. As part of the ABB SACE Tmax T4 series, it provides the main current-carrying and fault-interruption section required to build a T4V 250 circuit breaker using compatible ABB protection and operating components.
This product is supplied as a breaking part rather than a complete circuit breaker. The T4V performance level is the high-breaking-capacity variant of the Tmax T4 platform, making this unit suitable for industrial electrical distribution systems where substantial prospective short-circuit currents may be present.
The 1SDA054566R1 features a 250 A frame rating, four-pole configuration, fixed construction and front terminals. The T4V 250 platform supports demanding AC distribution applications and, in appropriate four-pole configurations, DC systems up to 1000 V DC, providing a robust foundation for specialist industrial circuit protection.
Key Advantages
- Genuine ABB SACE Tmax T4V 250 breaking part for compatible MCCB assemblies.
- 250 A frame rating for industrial power distribution applications.

High-Performance Breaking Unit for Tmax T4 Assemblies
The breaking part forms the main power interruption section of a moulded case circuit breaker, carrying normal circuit current and interrupting fault current when operated by the associated protection system. The ABB T4V 250 platform is designed for applications requiring high fault-interruption performance within a compact industrial circuit breaker format.
As a breaking unit, the 1SDA054566R1 is intended to form part of a correctly configured ABB Tmax T4 circuit breaker assembly rather than operate as a complete standalone protective device. Its four-pole fixed construction, front terminals and T4V performance level make it suitable for integration into industrial switchboards and specialist power distribution assemblies using compatible ABB components.
Typical Applications
- ABB SACE Tmax T4 moulded case circuit breaker assemblies.
- Industrial electrical power distribution systems.
- Electrical switchboards and distribution panels.
- High fault-level industrial installations.
- Industrial machinery electrical distribution.
- Specialist high-voltage DC distribution systems.
- Power generation and energy infrastructure.
- OEM switchboards and electrical distribution assemblies.
