TMA Thermal-Magnetic Protection for Tmax T4L
The TMA thermal-magnetic trip unit combines two complementary protection principles. Its thermal element responds to sustained overload conditions, while the magnetic element provides rapid operation during high-current short-circuit conditions. This provides straightforward circuit protection without requiring an electronic trip unit.
For the ABB 1SDA058137R1 configuration, the TMA unit is rated at 125 A and provides a magnetic setting range of 625–1250 A. This combination allows the circuit breaker to protect compatible three-phase distribution circuits while providing adjustment of the magnetic protection threshold within the specified range.
Typical Applications
- Three-phase low-voltage distribution systems.
- Industrial switchboards and distribution boards.
- Commercial electrical distribution panels.
- Feeder and distribution circuit protection.
- Circuits requiring thermal overload and magnetic short-circuit protection.
- Installations specified around compatible ABB Tmax T4L UL/CSA equipment.
