Overview
The Allen-Bradley 100-C16EJ400 is a compact IEC-standard contactor designed for motor control and industrial automation applications. This 16-ampere, 24V DC electronic coil contactor integrates seamlessly into Bulletin 100-C series control systems, offering drop-in replacement capability for OEM equipment and field upgrades. The integrated diode protection on the 24V DC coil reduces transient spikes and extends switching component life in demanding industrial environments.
Key Features
- 16A rated load with motor ratings up to 10HP @ 460V, 5HP @ 230V, 5HP @ 200V, and 15HP @ 575V
- 24V DC electronic coil with integrated diode for noise suppression and circuit protection
- 4 normally-open poles (4NO/0NC) for flexible control circuit design
- Line-side coil termination with screw terminals for secure, tool-free installation
- IEC standard construction ensures compatibility with European and international motor control architectures
- Motor-load rated for reliable performance in NEMA and IEC duty cycles
Technical Specifications
This contactor supports 50/60 Hz AC operation and delivers consistent electromagnetic switching performance across standard industrial voltage and frequency combinations. The compact footprint and standardized mounting allow direct substitution in legacy Bulletin 100-C panel layouts without panel redesign. Heavy-duty silver alloy contacts withstand repeated duty-cycle stress while maintaining low contact resistance.
Typical Applications
- Fixed and variable-speed AC motor starting and control
- Pump and fan motor control in HVAC systems
- Compressor and blower motor control
- Machine tool motor circuit protection
- Energy-efficient soft-start integration with reduced in-rush current
- System modernization in existing Bulletin 100-C installations
Compatibility & Replacements
The 100-C16EJ400 is part of the Bulletin 100-C IEC contactor family and is fully compatible with all standard Bulletin 100-C accessories, overload relays, and auxiliary contact modules. When replacing older contactors, verify coil voltage and pole configuration to ensure proper operation. Rockwell Automation maintains an extensive library of replacement and upgrade options; consult technical documentation or contact your distributor for alternative models suited to different voltage or horsepower requirements.
