This is the part you spec into a panel when the BOM calls for a 125 A thermal-magnetic MCCB with UL/CSA listing — no electronics, no adjustable trip curve, just a fixed thermal and magnetic response for straightforward feeder or motor branch protection.
What the 125 A TMF Trip Means for Fit
This is a non-adjustable, fixed-trip MCCB — you select it for a known load current where you don't need field-adjustable thermal or magnetic settings. Common in fixed-feeder applications, motor branch circuits where the overload relay handles the running protection, or as a main disconnect in a panel where the downstream coordination is already calculated. The 3-pole construction handles three-phase circuits up to 480Y/277 V or 600 V delta in UL/CSA installations.
Regulatory & Documentation
UL/CSA listing is explicit in the order code suffix — this variant is certified for North American installations. The brand provides standard compliance documentation (RoHS, REACH, UL file, IEC test reports) upon request through the sourcing channel. No separate CE marking is implied by the UL/CSA suffix; if CE is required for a European panel, verify the order code variant.
