ABB Thomas & Betts ERG4002 Electrical Relay Module

The ABB Thomas & Betts ERG4002 Sta-Kon crimp tool is a ratchet‑operated hand tool designed for crimping uninsulated Sta-Kon terminals in the 22–10 AWG range (Catalog No. ERG4002). It is used to form reliable crimps on small to mid‑size lugs and terminals in electrical distribution, panel wiring, and control cabinets. The ratchet mechanism provides consistent crimp pressure across each operation, helping ensure uniform results when crimping 22–10 AWG conductors. This ERG4002 model is part of ABB’s Sta-Kon crimp tool family and is commonly listed by ABB and authorized distributors under the Sta-Kon line. Typical uses include securing lugs and terminal ends on power and control wiring in electrical installations where compact tool size and precise crimps are required. The ERG4002 is referenced across multiple distributor catalogs for global markets, sometimes alongside related models that cover broader crimp ranges within the same family.
