In complex industrial applications requiring simultaneous control of multiple circuits with absolute precision, the Allen-Bradley 100-C23KF400 emerges as a superior solution within Rockwell Automation's Bulletin 100-C series. Featuring a specialized 4 N.O. main contact configuration and universal 230V 50/60Hz coil technology, this UL-certified quad-pole contactor delivers unmatched synchronization for multi-motor systems, phase-redundant circuits, and critical power distribution. Engineered for applications demanding perfect coordination between parallel loads in data centers, manufacturing automation, and energy infrastructure, the 100-C23KF400 sets a new benchmark in switching accuracy.

Engineering Innovations

1. Monolithic Switching Matrix

• 4 Identical N.O. Poles: Enables simultaneous engagement of multiple circuits with <0.3ms pole-to-pole variance – critical for balanced load distribution.

• Cross-Pole Arc Containment: Segregated arc chambers prevent flashover during high-current interruption (tested at 50kA prospective fault current).

2. Universal Coil Technology

• 230V 50/60Hz TC-851 Coil: ±20% voltage tolerance ensures reliable operation in unstable grids without derating.

• Energy-Optimized Design: Consumes only 3.5W during holding state (60% less than comparable 4-pole contactors).

3. Advanced Contact Material

• Silver-Graphite Composite: Withstands 750,000 AC-3 operations at 23A per pole with <1mV contact voltage drop.

• Anti-Welding Geometry: Asymmetric contact design prevents phase-to-phase adhesion during fault conditions.
