Overview
The Allen-Bradley 100S-C30EJ04C is a Rockwell Automation IEC safety contactor designed for mission-critical control circuits and feedback loops. Built with mechanically linked, positively guided contacts—a key safety requirement—this unit ensures that auxiliary contacts cannot change state if a main power pole welds, meeting international safety standards (IEC 60947-4-1) and UL/CSA certifications.
Key Features
- Mechanically Linked Contacts: Positively guided main and auxiliary contacts prevent contact welding failures from creating false safety signals.
- 24VDC Electronic Coil: Direct 24V DC (50/60 Hz compatible) operation eliminates the need for external coil suppressors in most control circuits.
- 3NO + 4NC Contact Configuration: Three normally open power poles rated at 30A; four normally closed auxiliary contacts for safety feedback, interlocking, and diagnostic monitoring.
- Compact DIN Rail Mounting: Space-efficient footprint for tight industrial control panels and safety-rated enclosures.
- Wide Operating Range: Temperature rated –25 to +60 °C; suitable for harsh factory and cleanroom environments.
- High Power Ratings: 10 kW @ 230V AC; 15 kW @ 400/415/500/690V AC (AC-3 industrial duty).
Technical Specifications

- Contact Type: Gold-plated bifurcated contacts with standard termination
- Coil Termination: Line-side connections
Typical Applications
- Emergency stop (E-stop) circuits and safety interlocks in manufacturing equipment
- Motor starter feedback control in conveyor, packaging, and assembly line systems
- Safety-rated load switching and machine tool control
- Industrial automation panels requiring ISO 13849-1 or SIL-rated safety functions
- HVAC and pump control systems with safety monitoring requirements
Compatibility & Replacements
The 100S-C30EJ04C is part of the Bulletin 100S/104S family of mechanically linked safety contactors from Rockwell Automation. It is a direct replacement for other 30A IEC safety contactors with identical coil voltage and contact configuration. When specifying replacements or upgrades, confirm coil voltage (24V DC in this model) and auxiliary contact count. For standard (non-safety) 30A motor control, the non-safety 100-C30 series offers similar electrical ratings but without mechanically linked contacts—not suitable for critical safety circuits.
