Typical Applications
The 100-C23D10 is widely deployed in:
- Three-phase AC motor starters and reversing duty
- Pump and fan control systems
- Compressor and HVAC equipment control
- General industrial machinery automation
- Modular starter assemblies paired with thermal overload relays
Compatibility & Replacements
The 100-C23D10 integrates seamlessly with the Bulletin 100-C and 104-C contactor family ecosystem. It pairs directly with Bulletin 193 solid-state overload relays, timing modules (electronic and pneumatic), and coil-mounted control accessories. Standard screw terminals allow integration into existing panel layouts without rewiring. When specifying replacements or upgrades, verify coil voltage and contact configuration to ensure drop-in compatibility with your control circuit.
