Why Choose the ABB T4L 250 Breaking Part 4P FF?
The ABB T4L 250 Breaking Part 4P FF, order code 1SDA054565R1, is a fixed 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 interruption section required to configure a T4L 250 circuit breaker with the appropriate compatible protection release.
This component is supplied as a breaking part rather than a complete circuit breaker, allowing suitable ABB Tmax T4 protection and operating components to be combined according to the requirements of the installation. The T4L performance level is designed for applications requiring high short-circuit interruption capability in industrial low-voltage distribution systems.
The 1SDA054565R1 has a 250 A rated uninterrupted current, four-pole configuration and fixed construction with front terminals. It is designed for operational voltages up to 690 V AC and 750 V DC and offers an ultimate short-circuit breaking capacity of up to 120 kA at 400–415 V AC.
Key Advantages
- Genuine ABB SACE Tmax T4L 250 breaking part for compatible circuit breaker configurations.
- 250 A rated uninterrupted current for industrial power distribution applications.
- Four-pole configuration for multi-pole AC and DC distribution systems.
- High T4L short-circuit breaking performance.
- Ultimate breaking capacity of 120 kA at 400–415 V AC.
- Rated operational voltage up to 690 V AC and 750 V DC.
- 1000 V rated insulation voltage and 8 kV impulse withstand voltage.
- Fixed construction with front terminals for switchboard integration.

High-Performance Breaking Unit for Tmax T4 Assemblies
The breaking part is the power interruption section of a moulded case circuit breaker and is designed to carry normal circuit current and interrupt high fault currents when operated by the appropriate protection system. The ABB T4L 250 platform provides high breaking performance for industrial electrical distribution systems where substantial prospective short-circuit currents may be present.
As a breaking unit, the 1SDA054565R1 is intended to form part of a correctly configured ABB Tmax T4 circuit breaker assembly rather than function as a complete standalone protective device. Its four-pole fixed construction, front terminals and high interruption capability make it suitable for integration into industrial switchboards and power distribution assemblies using compatible ABB components.
Typical Applications
- ABB Tmax T4 moulded case circuit breaker assemblies.
- Industrial electrical power distribution systems.
- Electrical switchboards and distribution panels.
- High fault-level industrial installations.
- Commercial and industrial power distribution.
- Industrial machinery electrical systems.
- Power generation and infrastructure installations.
- OEM switchboards and electrical distribution assemblies.
