Product Features
- No Built-In Auxiliary Contacts — Maximum Configuration Flexibility: The “-00” suffix means this contactor ships with no auxiliary contacts. This is the preferred choice when your application requires a specific combination of NO and NC contacts that differs from the pre-configured “-10” or “-01” variants, or when no auxiliary contact is needed at all. Up to 6 auxiliary contacts can be added: 4 via front-mount blocks (100-FA series) and 2 via side-mount blocks (100-SA/SB series).
- Reversible Coil Terminations: The 100-C30 series features reversible coil terminations — the A1/A2 coil terminals can be configured for either line-side or load-side coil connection, accommodating different panel wiring layouts without rewiring the contactor body.
- Built-In Surge Suppression: The Bulletin 100-C series includes built-in coil surge suppression as standard, protecting the coil from voltage spikes that can reduce contactor life in inductive control circuit environments.
- Side Mounting on Both Sides: Unlike the smaller 100-C09 through 100-C23 frame (which restricts auxiliary blocks to the left side due to double-numbering), the 100-C30 frame allows front and side mounting on either side, providing greater flexibility in panel layout and auxiliary contact configuration.
- Direct-Mount Overload Relay: The Allen-Bradley 193-series electronic overload relay and 592-series bimetallic overload relay mount directly to the 100-C30 to form a complete IEC motor starter. Select the overload range based on your motor’s full-load amperage.
- Electronic and Pneumatic Timing Modules: The 100-C30 accepts snap-on electronic timing modules and pneumatic timing modules for on-delay, off-delay, and star-delta timer applications — part of the comprehensive Bulletin 100-C accessory ecosystem.
- Global Certifications: UL 508 Listed, CSA Certified, IEC/EN 60947-4-1 and 60947-5-1 compliant, RoHS compliant, CE marked.

Frequently Asked Questions
What does “-00” mean in the 100-C30*00 catalog number?
The “00” suffix indicates no auxiliary contacts are included with the contactor. The asterisk (*) before “00” is the placeholder for the coil voltage code. For example, 100-C30D00 = 120V AC coil with no auxiliary contacts. Other aux suffixes: 10 = 1 NO, 01 = 1 NC, 11 = 1 NO + 1 NC. Choose the “00” variant when you want to add specific auxiliary contact blocks separately or when no auxiliary contact is required.
Why would I choose the 100-C30*00 (no aux) over the 100-C30*10 (1 NO)?
The “-00” variant is the right choice when: (1) your application genuinely needs no auxiliary contact, reducing cost; (2) you need a specific combination not available pre-installed — for example, 1 NC only (add 100-FA01) or 2 NO / 2 NC (add 100-FA22); or (3) you prefer to stock one base contactor and select aux contacts separately based on project requirements. If you simply need 1 NO for basic interlocking or feedback, the 100-C30*10 is a simpler single-order choice.
How many auxiliary contacts can be added to the 100-C30?
The 100-C30 frame supports up to 6 total auxiliary contacts via add-on blocks: up to 4 contacts from front-mount 100-FA series blocks, and up to 2 contacts from side-mount 100-SA / 100-SB series blocks. Both sides of the 100-C30 accept auxiliary blocks (unlike the smaller 100-C09–C23 frame which is left-side only). For AC coil contactors, up to 4 N.C. contacts can be mounted on the front; for DC coil contactors, up to 4 N.C. contacts on the front and 4 N.C. front or side.
What is the difference between 100-C23 and 100-C30?
The 100-C23 is rated at 23A AC-3 (15 HP @ 460V) while the 100-C30 is rated at 30A AC-3 (20 HP @ 460V). Beyond the current rating, the 100-C30 frame offers more auxiliary contact flexibility — both sides accept auxiliary blocks (vs left-side only on the C23 frame) and up to 6 total contacts are supported. The coil terminations on the C30 are also reversible between line and load side. Select based on your motor’s HP and FLA requirements.
Which overload relay is compatible with the 100-C30?
The Allen-Bradley 193-series electronic overload relay and 592-series bimetallic overload relay are both compatible with the 100-C30 for direct-mount motor starter assemblies. Select the appropriate model and current range to cover your motor’s full-load amperage. Call us at 1-800-222-5129 for overload selection assistance.
Does the 100-C30*00 qualify for same-day shipping?
Yes — stocked 100-C30 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.
