Overview
The Allen-Bradley 104-C23D22 is a compact, space-saving IEC reversing contactor designed for three-phase motor control and industrial automation systems. Allen-Bradley® Bulletin 104-C is a low power consumption contactor designed to control motors and other loads. Catalog item 104-C23D22 from Rockwell Automation® is a 23 A, 110 V 50 Hz / 120 V 60 Hz IEC reversing contactor. The unit incorporates one normally open and three normally closed contacts with line side coil termination, screw terminals, and motor load.
Key Features
- Reversing capability — enables forward/reverse motor control without external logic
- Auxiliary contact configuration — 1 NOC & 3 NCC for signaling and interlocking
- Screw-type terminals — secure, field-serviceable connections
- DIN rail mounting — compact footprint fits standard 35mm rail installations
- Multi-standard certification — C-TICK, CCC, CE, CSA, CUL, GOST, KC, UL
- Low power consumption design — reduces coil duty and thermal load
