AN16 / Freedom NEMA (Size 1, 27 A)
Eaton / Cutler-Hammer · NEMA Size 1
Eaton Freedom-series NEMA starter. Size 1, 27 A continuous. Common in packaged compressor skids and pump panels; C306 overloads dial FLA directly instead of using heaters.

Coil data
- Available coil voltages
- Coil codes: A = 120 V · B = 240 V · C = 480 V · D = 208 V · T = 24 V
- Inrush VA
- ≈ 190 VA
- Sealed (holding) VA
- ≈ 25 VA
- Pickup voltage
- ≥ 85% of rated
- Dropout voltage
- ≈ 40–65% of rated
Typical measured coil resistance (±15%, ballpark)
120 VAC (A)≈ 55–95 Ω
480 VAC (C)≈ 800–1,400 Ω
OL = open coil · near zero = shorted turns · coil-to-frame must read >1 MΩ.
Coil resistance checker
Pick the coil voltage, enter your meter reading across A1–A2 (coil disconnected), and compare it to the expected ballpark.
Ω
This model (120 VAC (A) table value)55 Ω–95 Ω
Generic small-frame 110–120 VAC150 Ω–450 Ω
Readings 2× high usually mean heat damage and a coil near end of life. Ballpark only (±15%+); electronic wide-range coils (e.g. ABB AF) read misleading values — test those at rated voltage instead. Always measure coil-to-frame too: must be >1 MΩ.
Terminals & accessories
Power/coil terminals: L1–L3 top, T1–T3 bottom; A1/A2 coil on front
Auxiliary contacts: C320 aux contact kits, side-mount
Companion overload: C306 bimetal (adjustable) or C396/C441 electronic overload

Field notes
- AN16DN0AB decode: AN16 starter · D = NEMA Size 1 · N0 = NEMA 1 enclosure · A = 120 V coil · B = heater-less bimetal.
- C306 overloads have a FLA dial AND a manual/auto reset selector — check which mode it's in before blaming a 'no reset'.
