Breaking capacity and trip curve
The C16F3TM100: The F breaking capacity code delivers 36 kA Icu at 380/415 V AC and 85 kA at 240 V AC, so it handles high available fault current on a 480Y/277 V or 208Y/120 V panelboard secondary. At 480 V AC the Icu is 35 kA (UL 60947-4-1 listing), and at 600 V AC it holds 10 kA. The TM-D trip provides thermal overload (L) and magnetic short-circuit (I) protection in one unit, adjustable via the front dials. Electrical endurance is 40,000 cycles at 440 V In/2 and 20,000 at full rated current — enough for frequent switching in a machine-tool or HVAC disconnect role.
IP40 front face and IK07 impact resistance suit enclosed panel installation where occasional tool contact is expected.
