Allen-Bradley 100S-C30EJ04BC Safety Contactor

Allen-Bradley 100S-C30EJ04BC is a three-pole safety contactor rated for 30 A, designed for safety-related motor-control applications in industrial machinery. It uses an electronic coil (EJ) with a 24 V DC control voltage and provides three normally open power poles to interrupt motor circuits. The unit is configured for line-side coil termination and pairs with safety-relay systems or safety PLCs to implement primary safeguarding functions such as emergency-stop and interlock logic. This model belongs to the IEC safety contactor family and is commonly used to switch medium-power loads in machines like conveyors, presses, and machine tools, offering reliable electrical isolation between control and power circuits while maintaining a compact 3-pole footprint.
