Terminal Blocks

Mount blocks to a panel or the surface of a machine. Also known as barrier terminal strips.

Space-Saver Terminal Blocks

A single row of terminals fits in narrow spaces.

High-Temperature Terminal Blocks

Blocks are made of ceramic to withstand elevated temperatures.

Quick and Secure Connect Terminal Blocks

The spring-clamp terminals on these blocks make wire installation faster than with other types of terminals. Push wire into the spring clamp for a secure connection that withstands vibration.

High-Current Terminal Blocks

These blocks handle at least twice as much current as standard terminal blocks.

Touch-Safe Terminal Blocks

High-Temperature Touch-Safe Terminal Blocks

Blocks are made of ceramic to withstand elevated temperatures.

Pluggable Touch-Safe Terminal Blocks

Combine a plug and a socket to form a terminal block—the two-piece design allows quick disconnection for equipment repairs.

Modular DIN-Rail Mount Terminal Blocks

Use with DIN 3 and DIN 1 rail. Add as many circuits as you need with these terminal blocks and accessories.

Quick and Secure Modular
DIN-Rail Mount Terminal Blocks

The spring-clamp terminals on these blocks make wire installation faster than other types of terminals. Push wire into the spring clamp for a secure connection that withstands vibration.
