Allen-Bradley 100S-C72DJ14C IEC Safety Contactor, 72A AC-3, 24V DC Coil with Diode, 3NO + 1NO/4NC Aux

Allen-Bradley 100S-C72DJ14C IEC Safety Contactor with Mechanically Linked Contacts

The Allen-Bradley 100S-C72DJ14C is a Bulletin 100S IEC safety contactor engineered for safety-related control systems requiring verified contact status feedback. It combines high current switching capability with mechanically linked auxiliary contacts to support compliant safety circuit design.

Mechanically Linked Auxiliary Contact Architecture

• Mechanically linked contacts prevent N.C. auxiliaries from changing state if a power pole welds
• Mirror contact behavior supports reliable safety relay and controller feedback
• Auxiliary configuration includes 1 N.O. and 4 N.C. contacts for series monitoring circuits
• Designed for use in safety-rated control applications

IEC Power Switching and Coil Design

The contactor is rated for 72 A at AC-3 duty and supports operating voltages up to 690 VAC. Its 24V DC control coil includes an integrated diode for surge suppression, reducing wiring complexity and protecting upstream control components.

Safety Control Applications

• Emergency stop and safety relay feedback circuits
• Machine safety interlocking systems
• Safety-rated motor control and power isolation
