Why Choose the ABB XT2L 160 TMA 160-1600 3p F F Circuit Breaker?
The ABB 1SDA067648R1 is an ABB SACE Tmax XT2L 160 three-pole moulded-case circuit breaker equipped with a TMA thermomagnetic trip unit. Rated at 160 A, it provides dependable overload and short-circuit protection for low-voltage power distribution applications.
The XT2L breaking-capacity version provides an ultimate short-circuit breaking capacity (Icu) of 120 kA at 415 V AC, making it suitable for demanding installations with high prospective fault currents. Its TMA release combines adjustable thermal overload protection with adjustable magnetic short-circuit protection in a robust electromechanical design.
Configured as a fixed three-pole circuit breaker with front terminals, the 1SDA067648R1 has a rated current of 160 A. The thermal setting can be adjusted from 112–160 A, while the instantaneous magnetic trip is adjustable from 800–1600 A, supporting effective coordination with the protected circuit.

Reliable Adjustable Thermomagnetic Circuit Protection
The ABB TMA trip unit combines adjustable thermal and magnetic protection within the circuit breaker. The thermal element responds to sustained overload currents and can be set from 112–160 A, helping protect conductors and connected equipment against excessive heating while allowing the protection threshold to be matched to the circuit.
For short-circuit protection, the magnetic release is adjustable from 800–1600 A. This allows the instantaneous trip threshold to be coordinated with the electrical installation while the XT2L breaking part provides the high interruption capability required to safely disconnect substantial fault currents.
Typical Applications
- Low-voltage power distribution panels.
- Industrial switchboards and distribution boards.
- Commercial electrical distribution systems.
- Three-phase feeder circuits.
- Cable and installation protection.
- Industrial machinery power supplies.
- Transformer and generator distribution circuits where appropriate protection coordination is applied.
- Installations with high prospective short-circuit currents.
- Fixed ABB SACE Tmax XT circuit breaker assemblies.
