The 125 A frame accepts line and load conductors sized for the full frame rating; the TMF trip unit's 15–500 A continuous-current band means the breaker can be ordered with the exact fixed-trip rating that matches the protected branch. Fixed-front terminals (the second 'F' in the order code) indicate the breaker ships without plug-in accessories — add auxiliary switches or shunt trips as separate line items if remote signaling or undervoltage release is required.
