Allen-Bradley 100S-C16J404BC AC 24V Contactor

The Allen-Bradley 100S-C16J404BC is a 16 A safety contactor in the 100S family, designed to control AC loads with a 24 VAC coil and four normally open contacts, delivering reliable switching for safety-related motor-control circuits. As a Bulletin 100S safety-contactor device, it is intended for use in guard interlock and emergency-stop applications where fail-safe circuit behavior is required, helping to isolate power to automated equipment like conveyors, presses, and packaging lines. The 100S-C16J404BC suffix encodes a 16 A load rating, four normally open contacts, and a 24 V AC coil configuration, placing it among Rockwell Automation’s 100S-series safety contactors built to meet common industrial automation safety requirements.
