Why Choose the ABB A1C 125 TMF 16-400 1p F F Circuit Breaker?
The ABB A1C 125 TMF 16-400 1p F F, order code 1SDA068745R1, is a single-pole moulded case circuit breaker from ABB's Tmax XT product family. Designed for low-voltage circuit protection, this configuration combines a compact A1C 125 breaker platform with a 16 A TMF thermomagnetic trip unit.
The integrated TMF fixed thermomagnetic release provides thermal overload protection at 16 A together with instantaneous magnetic short-circuit protection at 400 A. This straightforward protection technology makes the breaker suitable for circuits requiring reliable overload and fault-current protection without the complexity of an electronic trip unit.
The 1SDA068745R1 is supplied as a single-pole, fixed circuit breaker with front terminals. Its combination of compact construction, fixed thermomagnetic protection and ABB circuit-breaker engineering makes it suitable for industrial, commercial and OEM low-voltage distribution applications.

Reliable Fixed Thermomagnetic Protection
The TMF release combines two established protection principles in one compact device. Its thermal element responds to sustained overload conditions, helping protect conductors and connected equipment against excessive current over time, while the magnetic element provides rapid operation during high-current short-circuit faults.
For the 1SDA068745R1, the release is specified as TMF 16-400, providing 16 A thermal protection and a 400 A instantaneous magnetic trip level. Because these protection characteristics are fixed, the breaker offers a straightforward solution for applications where the required circuit-protection parameters are known in advance.
