Reliable Circuit Protection for Power Distribution
Moulded case circuit breakers such as the ABB XT4L protect electrical installations against overloads and short circuits by interrupting current when abnormal conditions occur. The TMA thermomagnetic trip unit combines adjustable thermal overload protection with adjustable magnetic short-circuit protection, allowing the breaker to be matched more closely to the requirements of the protected circuit.
The SACE Tmax XT family is engineered for integration into modern low-voltage switchboards and distribution equipment. The compact XT4 frame, fixed mounting arrangement, front terminals and high L-class interruption capability make the 1SDA075269R1 particularly suitable for applications where space efficiency and high fault-current protection are important.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial electrical distribution systems.
- Feeder and cable protection.
- Electrical switchboards and panel assemblies.
- Industrial machinery power distribution.
- Manufacturing and process installations.
