Reliable Circuit Protection for Power Distribution
Moulded case circuit breakers such as the ABB SACE Tmax T4L protect electrical distribution circuits against damaging overcurrents while also providing a convenient means of circuit isolation. The T4 platform combines compact construction with robust switching performance, making it suitable for demanding industrial and commercial low-voltage distribution applications.
The TMA thermomagnetic trip unit provides complementary overload and short-circuit protection. Its adjustable thermal element responds to sustained overload currents that could overheat cables and connected equipment, while the adjustable magnetic element provides rapid tripping during severe short-circuit conditions. This flexibility allows the breaker protection characteristics to be matched more closely to the requirements of the electrical circuit.
Typical Applications
- Industrial low-voltage distribution systems.
- Main and sub-distribution switchboards.
- Electrical control and distribution panels.
- Commercial building power distribution.
- Manufacturing and process installations.
- Machinery and plant electrical distribution.
