Allen-Bradley 100-C23KF01 The Purpose-Engineered Solution for Automotive Packaging and Heavy Machinery Applications

Allen-Bradley 100-C23KF01 Contactor: The Safety-Certified Workhorse for Critical De-Energization Circuits

In industrial safety systems where positive circuit interruption is non-negotiable, the Allen-Bradley 100-C23KF01 stands as a purpose-engineered solution within Rockwell Automation's Bulletin 100-C series. Featuring a specialized 0 N.O. / 1 N.C. auxiliary configuration and UL-certified 230V 50/60Hz coil, this contactor delivers failsafe performance for emergency stops, safety gate interlocks, and critical process shutdowns. Designed for North American markets requiring uncompromising compliance with NFPA 79 and ANSI B11.19, the 100-C23KF01 combines robust construction with diagnostic-ready safety features for automotive, packaging, and heavy machinery applications.

Core Safety Engineering

1. Fail-Safe Auxiliary Architecture

• Dedicated N.C. (Normally Closed) Contact: Opens immediately upon coil energization, providing hardwired confirmation of circuit de-energization for SIL 3 applications.

• 0 N.O. Design: Eliminates risk of accidental circuit closure - critical for OSHA-compliant lockout/tagout (LOTO) procedures.

2. Position-Optimized Terminal System

• Terminal Position 2 Marking: Pre-wired integration with safety relays like Allen-Bradley 440R-S12R2 without panel reconfiguration.

• Line-Side Screw Terminals: Tool-free verification points for voltage testing during maintenance.

3. Universal Coil Technology

• 230V 50/60Hz TC-851 Coil: ±15% voltage tolerance handles grid fluctuations in aging industrial facilities.

• Surge-Protected Design: Withstands 2.5kV transients without external suppressors.
