Why Choose the ABB XT2V 160 TMD 5-50 3p F F Circuit Breaker?
The ABB 1SDA067677R1 is an ABB SACE Tmax XT2V 160 three-pole moulded-case circuit breaker equipped with a TMD thermomagnetic trip unit. Rated at 5 A, it combines thermal overload protection with a 50 A magnetic short-circuit release for dependable protection of low-voltage electrical circuits.
The XT2V is the very-high-breaking-capacity version of the XT2 frame, with an ultimate short-circuit breaking capacity (Icu) class of 150 kA. This makes it particularly suitable for installations where high prospective fault currents require robust interruption capability from a compact moulded-case circuit breaker.
Configured as a fixed three-pole circuit breaker with front terminals, the 1SDA067677R1 is designed for straightforward integration into industrial and commercial distribution equipment. Its XT2 frame is rated at 160 A, while the fitted TMD release has a rated current of 5 A and a 50 A magnetic short-circuit setting.

High-Capacity Thermomagnetic Circuit Protection
The ABB TMD trip unit combines two established protection principles within the circuit breaker. Its thermal element responds to sustained overload currents that could otherwise cause excessive heating of cables and connected equipment, while the magnetic element provides rapid operation when a high-current short-circuit fault occurs.
For the 1SDA067677R1, the TMD release has a rated current of 5 A with a magnetic short-circuit setting of 50 A. Combined with the very-high-breaking-capacity XT2V platform, this provides dependable protection for low-current circuits installed within electrical systems where substantial 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.
- Generator and power distribution protection where correctly coordinated.
- Installations with high prospective short-circuit currents.
- Fixed ABB SACE Tmax XT circuit breaker assemblies.
