The IEC 1492-J120-B Screw-Type Terminal Block by Rockwell Automation makes a simple and practical addition to your wiring system. The 1492 family of terminal blocks provide greater ease-of-use and are a dependable solution for your application.

The 1492-J120-B module is a One-Circuit Standard Feed-Through Terminal Block, in blue. For your convenience it can be quickly and effortlessly mounted via DIN rail. This unit also offers higher protection as it has IP2X finger-safe housing, minimising risk of electric shock. It has a large housing temperature range of –50 to +120 °C (–58 to +248 °F) for increased application flexibility. The blue coloured housing enables easy visibility of the unit within the control cabinet.

The 1492 standard terminal blocks are designed to be used in single-circuit feed-through applications. The 1492-J modules feature a self-locking design with steel clamps and screws which ensures greater security and stability.

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.
