Why Choose the ABB XT2L 160 TMD 5-50 3p F F Circuit Breaker?
The ABB 1SDA067633R1 is an ABB SACE Tmax XT2L three-pole moulded-case circuit breaker equipped with a TMD thermomagnetic trip unit. Rated at 5 A, it combines adjustable thermal overload protection with a fixed 50 A magnetic short-circuit trip for dependable protection of low-voltage electrical circuits.
The TMD release provides two complementary protection functions. Its thermal element can be adjusted over a 3.5–5 A range to protect against sustained overload conditions, while the magnetic element operates at 50 A to provide rapid disconnection during high-current short-circuit faults.
Configured as a fixed three-pole circuit breaker with front terminals, the 1SDA067633R1 is designed for straightforward integration into industrial and commercial electrical panels. The Tmax XT2 platform combines compact construction with the flexibility required for modern low-voltage distribution and equipment protection applications.

Reliable Thermomagnetic Circuit Protection
The ABB TMD trip unit combines thermal and magnetic protection within the circuit breaker. The adjustable thermal element responds to sustained overload currents that could otherwise cause excessive heating of cables and connected equipment, while the magnetic element provides fast operation when a severe short-circuit current occurs.
For the 1SDA067633R1, the thermal protection can be adjusted from 3.5–5 A, while the instantaneous magnetic release operates at 50 A. This combination makes the XT2L suitable for protecting low-current circuits where both overload protection and rapid short-circuit interruption are required.
Typical Applications
- Low-voltage electrical distribution panels.
- Industrial control panels.
- Commercial electrical installations.
- Three-phase low-current circuits.
- Cable and feeder protection.
- Machinery and equipment power circuits.
- Transformer and installation protection applications.
- Fixed ABB SACE Tmax XT circuit breaker assemblies.
