Rockwell Automation Standard Terminal Blocks offer a classic solution for wiring connection and highly efficient distribution of power. They are leading the industry in providing a wide range of products with Short Circuit Current Ratings (SCCRs), such as terminal blocks, power blocks, circuit breakers, contactors, disconnects, and drives.

A terminal block is a modular component which secures two or more wires together inside an insulated frame. This keeps wiring safely and neatly organised, protecting other components in the circuit and minimising risk of electric shock to people working on or near them. They can be easily connected or disconnected within the block which provides easy troubleshooting and maintenance. They can feature different termination types, such as screw, spring-clamp, and push-in. They are used in a wide range of industrial, commercial, and domestic applications and are known to be a space-saving, cost-effective type of connector.
