Why Choose the ABB XT2V 160 TMD 4-40 3p F F Circuit Breaker?
The ABB 1SDA067676R1 is an ABB SACE Tmax XT2V 160 three-pole moulded-case circuit breaker equipped with a TMD thermomagnetic trip unit. Rated at 4 A, it combines thermal overload protection with a fixed 40 A instantaneous magnetic short-circuit release for dependable protection of low-voltage electrical circuits.
The XT2V is the high-breaking-capacity version of the XT2 frame, with an ultimate short-circuit breaking capacity (Icu) of up to 150 kA. This makes it particularly suitable for installations where very high prospective fault currents demand robust interruption performance in a compact moulded-case circuit breaker.
Configured as a fixed three-pole circuit breaker with front terminals, the 1SDA067676R1 is designed for straightforward integration into industrial and commercial distribution equipment. Its XT2 frame has a 160 A frame size, while the fitted TMD release is rated at 4 A with a 40 A instantaneous magnetic setting.

High-Capacity Thermomagnetic Circuit Protection
The ABB TMD trip unit combines two established protection principles within a single moulded-case circuit breaker. Its thermal element responds to sustained overload currents that could cause excessive heating of conductors and connected equipment, while the magnetic element provides rapid operation when a high short-circuit current occurs.
For the 1SDA067676R1, the TMD release is rated at 4 A with an instantaneous magnetic setting of 40 A. Combined with the high-breaking-capacity XT2V platform, this provides dependable protection for low-current circuits installed in electrical systems where exceptionally high prospective short-circuit currents may be present.
Typical Applications
- Low-voltage electrical distribution panels.
- Industrial switchboards and control panels.
- Commercial electrical distribution systems.
- Three-phase low-current circuits.
- Cable and feeder protection.
- Machinery and equipment power circuits.
- Auxiliary electrical distribution circuits.
- Installations with very high prospective short-circuit currents.
- Fixed ABB SACE Tmax XT circuit breaker assemblies.
