Product Features
- 1 NO Auxiliary Contact Included: The 100-C09\*10 ships with 1 Normally Open (NO) base-mounted auxiliary contact — the standard configuration for the 100-C09 frame. This contact is used for control circuit feedback, PLC inputs, or interlocking. If a 1 NC contact is needed instead, order the 100-C09\*01 variant. Up to 4 additional contacts can be added via a front-mount 100-FA block.
- Left-Side Auxiliary Mounting Only: Due to double-numbering on the terminal markings of the 100-C09 through 100-C23 frame, auxiliary contact blocks should be mounted on the left side only. Rockwell Automation recommends left-side mounting to avoid terminal identification confusion during wiring and inspection.
- Space-Saving Compact Design: The 100-C09 is the smallest frame in the Bulletin 100-C lineup and offers one of the most compact footprints available for a 9A, 3-pole IEC contactor with UL and IEC dual ratings. Ideal for high-density panel layouts and HVAC equipment with limited enclosure space.
- Built-In Surge Suppression: The 100-C series includes integrated coil surge suppression, extending coil life in inductive control circuit environments without requiring external suppressors.
- Direct-Mount Overload Relay: The Allen-Bradley 193-series electronic overload relay (including 193-E and 193-EE) and 592-series bimetallic overload relay both mount directly to the 100-C09 to form a complete IEC motor starter assembly.
- Replacement for 100-A Series: The 100-C09 is the current replacement for the older Allen-Bradley 100-A series contactors. The 100-C series offers improved coil efficiency, lower power consumption, and expanded accessory compatibility compared to the legacy 100-A line.
- Global Certifications: UL 508 Listed, CSA Certified, IEC/EN 60947-4-1 and 60947-5-1 compliant, RoHS compliant, CE marked for worldwide installation compliance.

Frequently Asked Questions
What does “-10” mean in 100-C09*10?
The “10” at the end of the catalog number indicates 1 Normally Open (NO) auxiliary contact is pre-installed on the contactor. The asterisk (*) before “10” is a placeholder for the coil voltage code. For example, 100-C09D10 = 120V AC coil with 1 NO aux contact. Other configurations: \*01 = 1 NC, \*00 = no aux contacts. The coil voltage letter (D, A, ZJ, KJ, C) is inserted in place of the asterisk.
What is the HP rating of the 100-C09 at 460V?
The 100-C09 is rated at 5 HP at 460V three-phase under AC-3 motor duty. At 230V three-phase the rating is 2 HP, and at 575V it is 7.5 HP. For single-phase applications: 0.5 HP at 115V and 1.5 HP at 230V. These ratings are from Rockwell Automation’s official technical data publication (100-TD013).
Why must auxiliary contacts be mounted on the left side of the 100-C09?
The 100-C09 through 100-C23 frame uses double-numbering on its terminal markings — both North American and international terminal designations are printed side-by-side. Rockwell Automation recommends left-side auxiliary mounting only for these frames to ensure clear terminal identification during wiring and inspection. This is a frame-specific note that does not apply to the larger 100-C30 through 100-C97 frames, which allow both left and right side mounting.
Which overload relay is compatible with the 100-C09?
The Allen-Bradley 193-series electronic overload relay (193-E and 193-EE models) and 592-series bimetallic overload relay are compatible with the 100-C09 for direct-mount motor starter assemblies. Select the model and current range that matches your motor’s full-load amperage. Call us at 1-800-222-5129 for overload selection assistance.
Can the 100-C09 replace an older Allen-Bradley 100-A series contactor?
The 100-C series is the current-generation replacement for the legacy 100-A series. The 100-C09 replaces the 100-A09 in most motor control applications, offering improved coil efficiency, lower power consumption, and a broader accessory ecosystem. However, the 100-C and 100-A series are not dimensionally identical — verify mounting footprint and terminal spacing before direct substitution in an existing panel. Call us at 1-800-222-5129 if you need help confirming compatibility.
Does the 100-C09*10 qualify for same-day shipping?
Yes — stocked 100-C09 variants 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 each individual variant page. For bulk orders or less common coil voltage variants, call us at 1-800-222-5129 or text your RFQ to 484-425-0652.
