IEC Spring-Clamp Terminal Blocks

IEC Spring-clamp Terminal Blocks offer screwless termination technology—a fast and practical solution for secure and durable connections. These high-density blocks reduce wiring time, minimize troubleshooting, and perform in severe conditions. Secure contact is durable under extreme conditions such as vibration type applications. We offer 20 types of IEC screw-type terminal blocks, including grounding, fuse, sensor, space-saver, mini, plug-in, and isolation.

1492 Mini-Blocks with Center Jumper Option

Bulletin 1492 Mini-blocks with Center Jumper are general single-circuit and quad-style, two-circuit feed-through and grounding blocks offering better durability. They are available in a broad range of colors in a smaller size. Our mini-blocks are a good choice for high-density applications and tight spaces and can be rail- or panel-mounted.


Bulletin 1492 Multi-Circuit Feed-Through IEC Spring-Clamp Terminal Blocks

1492 Multi-Circuit Feed-Through

Bulletin 1492 Multi-circuit Feed-through Terminal Blocks are ideal for applications where control signals must be distributed and collected through the same blocks. The blocks are a good solution for high-density wiring applications and are available in nine colors.


Bulletin 1492 Neutral Disconnect & Installation IEC Spring-Clamp Terminal Blocks

1492 Neutral Disconnect & Installation

Bulletin 1492 Neutral Disconnect and Installation Terminal Blocks offer increased safety by requiring a tool to open or close a circuit. These blocks work with a series of feed-through circuits, ground circuits, and circuits with a direct connection to a bus bar. This bus bar runs the full length of the terminal blocks to a connection block that is mounted further down the rail for an isolated neutral connection.


Bulletin 1492 Panel Mount Mini-Block IEC Spring-Clamp Terminal Blocks

1492 Panel Mount Mini-Blocks

Bulletin 1492 Panel Mount Mini-blocks are general single-circuit feed-through blocks that offer durability and are available in a broad range of colors. They are a good choice for high-density applications and tight spaces.


Bulletin 1492 Plug-In Style & Analog Loop Control IEC Spring-Clamp Terminal Blocks

1492 Plug-In Style & Analog Loop Control

Bulletin 1492 Plug-in and Analog Loop Control Terminal Blocks provide a means of plugging-in discrete electronic components, circuit protection fuses, or a circuit isolation disconnect plug where space is limited. This line includes a terminal block with two feed-through circuits and one ground connection.


Bulletin 1492 Power Distribution IEC Spring-Clamp Terminal Blocks

1492 Power Distribution

Bulletin 1492 Power Distribution Terminal Blocks with feeder spacing are available in numerous connector configurations to help meet the needs of your application. Hinged covers allow easier access and better protection from accidental contact.


Bulletin 1492 Sensor IEC Spring-Clamp Terminal Blocks

1492 Sensor

Bulletin 1492 Sensor Terminal Blocks are plug-in style blocks that are designed for 3-wire applications. Plug-in terminals are internally jumpered when installed in a bank. They are available with status indicators for 10…30 V voltage ranges.


Bulletin 1492 Specialty Feed-Through IEC Spring-Clamp Terminal Blocks

1492 Specialty Feed-Through

Bulletin 1492 Specialty Feed-through Terminal Blocks are two-level blocks with a common link connecting the two circuits. This link creates a single block with two connection points on each side.


Bulletin 1492 Standard Feed-Through IEC Spring-Clamp Terminal Blocks

1492 Standard Feed-Through

Bulletin 1492 Standard Feed-through Terminal Blocks for single-circuit feed-through applications are available in nine colors and several sizes. Many are available in triple- and quad-connection blocks.
