Product Description
Allen-Bradley 100-C12-10 Contactor — 12A, 3-Pole, 7.5 HP @ 460V
The Allen-Bradley 100-C12-10 is a 12A, 3-pole IEC contactor from Rockwell Automation’s Bulletin 100-C series. Rated at 7.5 HP at 460V three-phase (12A AC-3 / 32A AC-1), the 100-C12-10 includes 1 Normally Open (NO) base-mounted auxiliary contact as standard (the “-10” suffix). The coil voltage is selected by catalog number suffix — see the table below. Compatible direct-mount thermal overload relays from the 193-T series are available for complete motor starter assemblies.

Product Features
- 7.5 HP at 460V: The 100-C12-10 is rated for 7.5 HP at 460V three-phase (12A AC-3 / 32A AC-1), suitable for motor starters in pumps, fans, conveyors, and general industrial applications. It is also rated 3 HP at 230V and 10 HP at 575V three-phase.
- 1 NO Auxiliary Contact Included: The “-10” suffix designates 1 Normally Open (NO) base-mounted auxiliary contact. This is 1 NO only — not 1 NO + 1 NC. For 1 NC only, order the “-01” variant. Additional auxiliary contacts can be added via left-side mount auxiliary blocks.
- Left-Side Auxiliary Mount Only: On the 100-C09 through 100-C23 frames, additional auxiliary contact blocks can only be mounted on the left side of the contactor. The larger 100-C30 frame allows mounting on both sides. This means the total auxiliary contact capacity on the 100-C12 is limited compared to the 100-C30 and above.
- Same Frame as 100-C16: The 100-C12 and 100-C16 share the same physical frame. If a higher HP rating (10 HP @ 460V) or higher current capacity (16A AC-3) is needed, the 100-C16 is a drop-in upgrade in the same frame footprint without requiring panel modifications.
- 193-T Series Thermal Overload Compatible: The Allen-Bradley 193-T series direct-mount thermal overload relays mount directly to the 100-C12 load terminals for a complete motor starter assembly. Three current ranges are available: 1–5A, 3.2–16A, and 5.4–27A. Select based on your motor’s full-load amperage. Call Kent Electrical Supply at 1-800-222-5129 for overload selection assistance.
- DIN Rail or Base Mount: The 100-C12-10 mounts on standard 35mm DIN rail or directly to a panel backplate via base mount. Screw terminals standard.

Frequently Asked Questions
What does the "-10" suffix mean on the 100-C12-10?
The “-10” suffix designates the auxiliary contact configuration: 1 Normally Open (NO) contact included. This is 1 NO only — not 1 NO + 1 NC. The first digit indicates the number of NO contacts and the second digit indicates NC contacts, so “10” = 1 NO, 0 NC. For 1 NC only, order the “-01” variant. The coil voltage is specified by an additional letter suffix after the auxiliary suffix (e.g., 100-C12D10 = 120V AC coil with 1 NO aux).
What is the difference between the 100-C12 and the 100-C16?
The 100-C12 (12A AC-3, 7.5 HP @ 460V) and 100-C16 (16A AC-3, 10 HP @ 460V) share the same physical frame size. This means a 100-C16 is a direct drop-in upgrade for any panel that currently uses a 100-C12, providing 33% more current capacity and higher HP rating without any panel modification. If your application is near the 12A limit or if future motor upgrades are anticipated, the 100-C16 may be the better long-term choice.
What overload relay is compatible with the 100-C12-10?
The 100-C12-10 is compatible with Allen-Bradley 193-T series thermal overload relays, which mount directly to the T1-T2-T3 load terminals. Three current adjustment ranges are available: 1–5A, 3.2–16A, and 5.4–27A. For a 7.5 HP / 460V motor (FLA approximately 11A), the 3.2–16A range is typically appropriate. Call Kent Electrical Supply at 1-800-222-5129 for overload selection assistance.
Can auxiliary contacts be added to both sides of the 100-C12?
No — on the 100-C12 (and 100-C09, 100-C16, 100-C23), auxiliary contact blocks can only be mounted on the left side of the contactor. Both-side mounting is available on the larger 100-C30 frame and above. If your application requires auxiliary contacts on both sides, the 100-C30 is the smallest frame that supports this configuration.
Does the 100-C12-10 qualify for same-day shipping?
Yes — stocked 100-C12-10 coil variants ship same business day from Kent Electrical Supply’s warehouse in Emmaus, PA when ordered before 4:00 PM EST. For bulk orders, 193-T overload relays, or auxiliary contact blocks, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
