100-C09 (9 A)
Allen-Bradley (Rockwell) · 100-C 9–23 A frame
Rockwell's IEC line — standard in plants that standardize on AB controls. 9 A AC-3, gold-plated bifurcated aux contacts on some versions for PLC-level signals.

Coil data
- Available coil voltages
- Coil codes: DJ = 24 V 50/60 Hz · KG = 110/120 V · KF = 230/240 V · KN = 400 V
- Inrush VA
- ≈ 70 VA
- Sealed (holding) VA
- ≈ 8 VA
- Pickup voltage
- 85–110% of rated
- Dropout voltage
- 20–75% of rated
Typical measured coil resistance (±15%, ballpark)
24 VAC (DJ)≈ 6–10 Ω
120 VAC (KG)≈ 140–240 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 (24 VAC (DJ) table value)6 Ω–10 Ω
Generic small-frame 24 VAC8 Ω–16 Ω
OL = open coil. 0–2 Ω = shorted turns (often from a cooked transformer). 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: 1/3/5 in, 2/4/6 out; A1/A2
Auxiliary contacts: 1 aux built in; 100-F front-mount and 100-S side-mount blocks
Companion overload: 193-EA/EB (E100) electronic or 193-TA bimetal

Field notes
- Suffix …10 = 1 NO aux, …01 = 1 NC aux. Read the full cat no. before ordering a replacement.
- AB aux blocks are keyed to the C-frame generation — old 100-A blocks do not fit 100-C.
