Why Choose the ABB XT1N 125 TMF 60-600 4p F F UL/CSA Circuit Breaker?
The ABB XT1N 125 TMF 60-600 4p F F UL/CSA, order code 1SDA074657R1, is a compact four-pole moulded case circuit breaker designed for dependable overload and short-circuit protection in low-voltage electrical distribution systems. As part of the ABB SACE Tmax XT / T-Max XT 250 Range, this UL/CSA version combines compact XT1 construction with reliable thermomagnetic protection for industrial and commercial applications.
The breaker incorporates an ABB TMF thermomagnetic trip unit rated at 60 A, with instantaneous magnetic protection at 600 A. Its thermal element protects circuits against sustained overload conditions, while the magnetic element provides rapid tripping during high-current short circuits.
This XT1N configuration features a four-pole fixed construction with front terminals, a rated voltage of 600Y/347 V AC and an N-class interruption rating of 25 kA at 480 V AC. These characteristics make it well suited to UL-compliant switchboards, distribution panels and industrial control assemblies.

Reliable Thermomagnetic Circuit Protection
The TMF thermomagnetic release provides two complementary protection functions within a compact mechanical design. Thermal protection responds to sustained overload currents, while instantaneous magnetic protection rapidly disconnects the circuit when severe short-circuit currents occur.
ABB Tmax XT circuit breakers are designed for compact integration into low-voltage distribution equipment. The four-pole fixed configuration and front terminals of the 1SDA074657R1 make it a practical solution for switchboards, machinery panels and distribution assemblies requiring UL-certified circuit protection.
Typical Applications
- Industrial low-voltage distribution boards.
- Commercial electrical distribution systems.
- UL/CSA switchboards and control panels.
- Feeder and branch circuit protection.
- Industrial machinery and OEM electrical assemblies.
- Four-pole power distribution and isolation applications.
