Product Description
Allen-Bradley 100-C23 Bulletin 100-C IEC Contactor — 23A, 3-Pole
The Allen-Bradley 100-C23 is a 23A, 3-pole IEC contactor from the Rockwell Automation Bulletin 100-C series. Rated for 7.5 HP at 230V and 15 HP at 460V three-phase (23A AC-3 / 32A AC-1), the 100-C23 is a compact, space-saving contactor designed for motor control and load switching in industrial automation panels. The "-10" suffix in the catalog number indicates the included 1 Normally Open (NO) auxiliary contact. The coil voltage is encoded in the catalog number prefix — select from 120V AC, 240V AC, 24V DC, and other options below. Accessory auxiliary contact blocks (100-FA front-mount, 100-SA/SB side-mount) can be added to expand control circuit capability.

Product Features
- 1 N.O. Auxiliary Contact Included: The "-10" suffix means the 100-C23 ships with 1 Normally Open (NO) auxiliary contact pre-installed. This is the standard configuration for 100-C contactors and is used for control circuit feedback, PLC inputs, or interlocking. Note: this is 1 NO only — if you need 1 NO + 1 NC, add a 100-FA11 front-mount block or a 100-SA11 side-mount block.
- Expandable Auxiliary Contacts: The 100-C23 accepts snap-on auxiliary contact blocks for expanded control: 100-FA series (front-mount, up to 4 contacts) and 100-SA / 100-SB series (side-mount). Left-side mounting is recommended for the 100-C09 through 100-C23 frame due to double-numbering on the terminals. Front-mount blocks may also be ordered with screwless (spring-cage) terminals using the “100-CR” prefix.
- Compact Bulletin 100-C Design: The 100-C series is Rockwell Automation’s space-saving, low-power-consumption IEC contactor platform. The 100-C23 frame is compact enough for tight panel layouts while providing 23A AC-3 capability — ideal for 15 HP motor control at 460V three-phase.
- Direct-Mount Overload Relay: The Allen-Bradley 193-series electronic overload relay and 592-series bimetallic overload relay both mount directly to the 100-C23 to form a complete IEC motor starter. Select the overload range based on your motor’s full-load amperage.
- DIN Rail or Panel Mount: Mounts on standard 35mm DIN rail or directly to a panel backplate via screw mount. Screw terminals are standard; screwless (spring-cage) front-mount terminals are also available on select accessories (100-CR prefix).
- Global Certifications: UL 508 Listed, CSA Certified, IEC/EN 60947-4-1 and 60947-5-1 compliant, CE marked for worldwide installation compliance.

Frequently Asked Questions
What does the "*" mean in the catalog number 100-C23*10?
The asterisk (*) in 100-C23*10 is a placeholder for the coil voltage code, which must be specified when ordering. For example, 100-C23D10 = 120V AC coil, 100-C23A10 = 240V AC coil, and 100-C23ZJ10 = 24V DC coil. The 10 at the end indicates 1 N.O. auxiliary contact is included. Always specify the complete catalog number including the coil voltage code when ordering.
What is the HP rating of the 100-C23 at 460V?
The Allen-Bradley 100-C23 is rated at 15 HP at 460V three-phase under AC-3 motor duty. At 230V three-phase the rating is 7.5 HP, and at 575V it is also 15 HP. Note that some older references or third-party listings may show 10 HP at 460V — the correct rating from Rockwell Automation’s own technical data publication (100-TD013) is 15 HP at 460V.
What auxiliary contacts come with the 100-C23*10?
The "-10" suffix means the contactor includes 1 N.O. auxiliary contact as standard. This is not 1 NO + 1 NC — it is a single normally-open contact only. If your application requires a normally-closed contact or additional contacts, add a 100-FA11 front-mount block (1 NO / 1 NC), a 100-FA22 (2 NO / 2 NC), or a 100-SA11 side-mount block. Note: for the 100-C09 through C23 frame size, auxiliary contacts should be mounted on the left side only due to double-numbering on the right-side terminals.
Which overload relay is compatible with the 100-C23?
The Allen-Bradley 193-series electronic overload relay and 592-series bimetallic overload relay are both compatible with the 100-C23 for direct-mount motor starter assemblies. Select the appropriate model and current range to match your motor’s full-load amperage. Call Kent Electrical Supply at 1-800-222-5129 for overload selection assistance.
How does the 100-C23 compare to the Schneider LC1D32 or LS Electric MC-32A?
All three are 3-pole IEC contactors in the 23–32A range for motor control at 460V three-phase. The Allen-Bradley 100-C23 is rated 23A AC-3 (15 HP @ 460V) and includes 1 NO aux contact. The Schneider LC1D32 is rated 32A AC-3 (20 HP @ 460V) with no built-in aux contacts (LA1D blocks add-on). The LS Electric MC-32A is also 32A AC-3 (20 HP @ 460V) and includes 2 NO / 2 NC aux contacts as standard. These are not interchangeable drop-ins — contact us at 1-800-222-5129 if you need help selecting the right contactor for your application.
Does the 100-C23 qualify for same-day shipping?
Yes — stocked variants of the 100-C23 ship same business day from Kent Electrical Supply’s warehouse in Emmaus, PA when ordered before 4:00 PM EST. Current stock quantities are shown on the individual variant pages. For bulk orders or less common coil voltage variants, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
