Reliable Thermomagnetic Protection for Low-Voltage Circuits
Thermomagnetic moulded case circuit breakers combine two established protection principles in a single device. The thermal element responds to sustained overload conditions, while the magnetic element operates rapidly when high short-circuit currents occur. This provides dependable protection without the additional configuration requirements of an electronic trip unit.
The ABB XT2N 160 1SDA070127R1 combines this proven TMD protection technology with the compact Tmax XT2 platform. Its 16 A rating, 300 A magnetic setting, four-pole construction and 50 °C reference-temperature specification make it particularly suitable for low-current feeders and distribution circuits requiring robust, straightforward protection.
Typical Applications
- Industrial low-voltage distribution systems.
- Commercial building switchboards and distribution panels.
- Four-pole feeder and branch-circuit protection.
- Machinery and automation power distribution.
- Manufacturing and process equipment.
- Electrical installations requiring thermomagnetic overload and short-circuit protection.
- OEM switchgear and electrical panel assemblies.
