Allen-bradley 100FA02 Auxiliary Contact Block 2 Nc

Product Description

The ALLEN-BRADLEY 100FA02 is a front-mounting auxiliary contact block designed for use with 100-C series contactors in motor control applications. It provides two normally closed (NC) contacts used for logic signals, interlock circuits, or status feedback in control panels and motor control centers. The block uses screw terminals for straightforward field wiring. It is a Rockwell Automation MCS accessory intended for installation by licensed electricians and industrial control technicians working with IEC-style contactor assemblies.

This auxiliary contact block is suited for commercial and industrial motor control applications where additional NC contacts are needed beyond those provided by the base contactor. It mounts to the front of compatible contactors, keeping the panel footprint compact. Typical installations include motor starters, reversing contactors, and control logic circuits where status or interlock signals are required.

Key Features

• Two normally closed (2 NC) contacts for logic or interlock signal use
• Front-mounting design attaches directly to the face of compatible contactors
• Screw terminals for reliable, tool-accessible field wiring
• Compatible with MCS 100-C, 104-C, 700-CF, and 700S-CF contactor families
• Lightweight at 0.04 pounds, adding minimal mass to the contactor assembly

Compatibility

Designed for use with Allen-Bradley 100-C contactors and compatible as an accessory with MCS 100-C, 104-C, 700-CF, and 700S-CF series contactors.

Installation Notes

Installation should be performed by a qualified electrician or industrial control technician. De-energize and lock out the control panel per NFPA 70E procedures before attaching or removing the contact block. The block snaps or mounts to the front face of the contactor; verify the contactor series matches the compatible families listed before installation. Wiring of auxiliary contacts must comply with applicable NEC requirements for control circuit conductors.
