General Electric MACN431AT is a top-mount auxiliary contact block that provides three normally open (NO) contacts and one normally closed (NC) contact. Designed as an add-on for GE equipment, it adds signaling contacts without modifying the main power path, enabling independent control circuit feedback via a single unit. The MACN431AT configuration—3 NO / 1 NC—offers a compact, integrated solution for expanding contact availability on GE assemblies.
