It is a 3-pole device certified to UL/CSA standards, meaning it is accepted in North American panel builds where UL 489 or CSA C22.2 No. 5 applies.
The 225 A frame size and TMF 200-2000 trip unit mean this breaker is sized for feeder or main service applications where the continuous load falls within the adjustable thermal-magnetic range. The TMF trip provides fixed thermal and magnetic settings, so it is a drop-in replacement for designs already specifying that trip curve — no field adjustment of the magnetic pickup. The UL/CSA certification covers the breaker for use in North American panelboards and switchboards. For an integrator or site electrical engineer, that means the SCCR (short-circuit current rating) and interrupting capacity are documented per UL 489, and the breaker can be applied without additional derating in UL-listed assemblies.
