Our IEC Screw-type Terminal Blocks meet recognized international IEC standards. Our finger-safe blocks are designed for DIN rail mounting. We offer a wide range of high-density IEC block types, from general feed-through for control wiring to specialty blocks for grounding and isolation, plus thermocouple blocks designed for temperature-dependent process control applications.
IEC Screw-type Terminal Blocks
Double Level Plug-in Terminal Blocks
Our Bulletin 1492 Double Level, Plug-in Screw-type Terminal Blocks provide a means of plugging in discrete electronic components, circuit protection fuses, or circuit isolation disconnect plugs which helps save valuable panel space.
Thermocouple IEC Screw-type
Our Bulletin 1492 Thermocouple IEC Screw-type Terminal Blocks are two-circuit terminal blocks with current bars made of thermocouple material. You can use them in process control to prevent the creation of additional EMF voltages at the wire-to-terminal block connections.
Standard Feed-through IEC Screw-type Terminal Blocks
Our Bulletin 1492 Standard Feed-through IEC Screw-type Terminal Blocks are designed for single-circuit feed-through applications. These terminal blocks are available in several sizes and colors to accommodate different wire ranges and have multi-wire capabilities.
Stab-connect Feed-through IEC Screw-type Terminal Blocks
Our Bulletin 1492 Stab-connect Feed-through IEC Screw-type Terminal Blocks have stab connections on one side of terminal block. They are available in single circuit or two-level, two-circuit versions.
Specialty Feed-through IEC Screw-type Terminal Blocks
Our Bulletin 1492 Specialty Feed-through IEC Screw-type Terminal Blocks have test plugs and adapters that identify the presence of voltage and perform simple diagnostic measuring of voltage. Feed-through terminal blocks are available with a test plug that breaks the circuit, forcing the current to run through a meter connected to the circuit-break test plug. Make-before-break or break-before-make test plugs can be used with the testing terminal block.
Space-saver Grounding IEC Screw-type Terminal Blocks
Our Bulletin 1492 Space-saver Grounding IEC Screw-type Terminal Blocks provide an easy-to-identify, convenient, neatly organized grounding bus that is mounted on the DIN rail.
Space-saver Feed-through IEC Screw-type Terminal Blocks
Our Bulletin 1492 Space-saver Feed-through IEC Screw-type Terminal Blocks are compact terminal blocks with multi-wire capability for single-circuit applications. We offer these terminal blocks in nine colors and several sizes to accommodate your wire range requirements.
Single-circuit Neutral Disconnect IEC Screw-type Terminal Blocks
Our Bulletin 1492 Single-circuit Neutral Disconnect IEC Screw-type Terminal Blocks offer increased safety through a disconnect that requires a tool to open or close a circuit. This block is connected to a bus bar that runs the full length of the terminal blocks to a connection block that is mounted further down the rail for an isolated neutral connection.
Sensor IEC Screw-type Terminal Blocks
Our Bulletin 1492 Sensor IEC Screw-type Terminal Blocks conveniently provide all connections needed for three-wire applications in one terminal block. This design helps you save panel space.
Process IEC Screw-type Terminal Blocks
Our Bulletin 1492-JP Process IEC Screw-type Terminal Blocks are designed specifically for process marshaling applications to save 45% panel space and improve the performance of signal routing and distribution.
Plug-in IEC Screw-type Terminal Blocks
Our Bulletin 1492 Plug-in IEC Screw-type Terminal Blocks provide a means of plugging-in discrete electronic components, circuit protection fuses, or a circuit isolation disconnect plug for applications where space is limited.
Neutral Disconnect & Installation IEC Screw-type Terminal Blocks
Our Bulletin Neutral Disconnect and Installation IEC Screw-type Terminal Blocks offer increased safety by requiring a tool to open or close a circuit. This system works with a series of feed-through circuits, ground circuits, and circuits with a direct connection to a bus bar that runs the full length of the terminal blocks to a connection block that is mounted further down the rail for an isolated neutral connection.
Multi-circuit Feed-through IEC Screw-type Terminal Blocks
Our Bulletin 1492 Multi-circuit Feed-through IEC Screw-type 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.
Mini-blocks IEC Screw-type Terminal Blocks
Our Bulletin 1492 Mini-blocks IEC Screw-type Terminal Blocks are general single- and double-level feed-through and grounding blocks. These durable terminal blocks are available in a broad range of colors in a smaller size.
Isolation IEC Screw-type Terminal Blocks
Our Bulletin 1492 Isolation IEC Screw-type Terminal Blocks provide an easier and more convenient means to open a circuit without rewiring.
Internal Component IEC Screw-type Terminal Blocks
Our Bulletin 1492 Internal Component IEC Screw-type Terminal Blocks have internal fixed electronic components. Component blocks are available with diode forward, diode reverse, surge suppressor, or a range of resistor values.
Grounding IEC Screw-type Terminal Blocks
Our Bulletin 1492 Grounding IEC Screw-type Terminal Blocks provide an easy-to-identify, convenient, neatly organized grounding bus that is mounted on the DIN rail.
Fuse IEC Screw-type Terminal Blocks
Our Bulletin 1492 Fuse IEC Screw-type Terminal Blocks are hinged-arm fuse blocks for better overcurrent protection. The blocks mount directly on DIN rail. Our fuse blocks are available in a range of sizes for a range of different fuses, with or without blown fuse indication.
