100-C30B10 IEC Contactor The Ultimate Solution for High-Voltage Motor Control in Demanding Industrial Environments

Allen-Bradley 100-C30B10 Contactor: The High-Voltage Workhorse for Demanding Industrial Motor Control

In heavy industrial environments where voltage stability challenges conventional components, the Allen-Bradley 100-C30B10 emerges as a ruggedized solution within Rockwell Automation's Bulletin 100-C series. Engineered with a specialized 440-480V dual-frequency coil and reinforced 30A contact capacity, this UL-certified contactor delivers uncompromising performance in mining, oil & gas, and heavy manufacturing applications where voltage fluctuations and high-inrush loads demand superior electrical endurance.

⚡ Core Engineering Innovations

1. High-Voltage Coil System

• TC-475 Universal Coil: Operates at 440V 50Hz or 480V 60Hz (±10% tolerance) – eliminating need for control transformers in 480V systems

• Surge-Resistant Design: Withstands 4kV voltage spikes without external suppressors (IEC 61000-4-5)

2. Heavy-Duty Contact Architecture

• 30A AC-3 Rating: 25% higher than standard 23A contactors for demanding motor starts

• Silver-Cadmium Oxide Contacts: 1.2 million electrical operations at full load

3. Position-Optimized Terminals

• Terminal Position 1 Marking: Direct replacement compatibility with legacy systems

• Vibration-Proof Screw Terminals: Maintain integrity under 15G shock (tested per IEC 60068-2-27)
