For a terminal block that provides superior reliability, simplified installation, and essential durability the IEC 1492-J4-B Screw Type Standard Feed Through Terminal Block by Rockwell Automation is an ideal solution. The 1492-J family of terminal blocks meets recognised international IEC standards to improve the safety and efficiency of your control cabinet and give you absolute peace-of-mind.

The 1492-J4-B module is a One-Circuit Standard Feed-Through Terminal Block, in blue. The housing temperature range is -50 to +120°C (-58…+248°F). This block has a secure self-locking screw type clamp design with steel clamps and screws. It can be mounted on a DIN rail, offering easy installation, and is a simple solution for efficient organisation of your wiring system. It is specifically designed for single-circuit feed-through applications. This terminal block reduces risk of electric shock due to its IP2X finger safe housing.

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.
