Industrial 14-226-593-009 Auxiliary Contact Block

The 14-226-593-009 auxiliary contact block adds extra switching contacts to contactors, relays, or motor starters, enabling control circuit monitoring, interlocking, and status indication in industrial automation environments. It is designed to switch low-power control circuits and provide feedback signals, with configuration options for normally open or normally closed contacts (NO/NC) depending on setup, and is rated for 10 A continuous current and up to 600 VAC. Mounting is via snap-on or side mount to compatible contactors or relays, and it supports DC pilot duty operation. Typical applications include motor control centers, industrial automation systems, HVAC equipment, and machinery control panels where additional control circuitry, feedback, interlocks, and monitoring are required for reliable operation. The block is designed to work with contactors, relays, motor starters, and control panels and adheres to standards referencing NEMA pilot duty ratings for control circuits. In the field, it is commonly installed as an auxiliary switching and monitoring element, with common replacements including ABB NF Series Auxiliary Contact Blocks, Siemens 3RH Auxiliary Contacts, and Schneider Electric TeSys Auxiliary Contact Blocks.
