Covers—Snap onto the exposed side of a terminal block to prevent accidental contact with a live wire.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Bar Jumpers—Metal poles create an electrical connection between blocks, so you can connect multiple components with a single wire. Blocks must be the same width for the jumpers to fit. Cut jumpers to size with a hacksaw or high-force wire cutter. Add covers so jumpers don't touch the screws on the outermost blocks.

Insulation—Terminal blocks with insulated jumpers maintain their IP20 rating to prevent shocks and short circuits. Blocks with noninsulated jumpers lose their IP20 rating for touch protection because the jumpers introduce exposed metal to the circuit.

Connect grounding wire to DIN rail so fault currents can safely flow to ground. These terminal blocks should only be used for grounding circuits.

End Stops—Mount at the end of a group of terminal blocks so they don't slide when vibrated or bumped.

Install a fuse in the built-in fuse holder so excess current doesn't damage your equipment. If the current exceeds the limit, the fuse will blow and cut power to connected components.

Test and troubleshoot circuits without removing any wire. Flip the tab by hand or with a screwdriver to open and close the circuit.

Adjacent Jumpers—Metal poles create an electrical connection between adjacent terminal blocks, so you can connect multiple components with a single wire. Blocks must be the same width for the jumpers to fit.

Insulation—Terminal blocks with insulated jumpers maintain their IP20 rating to prevent shocks and short circuits. Blocks with noninsulated jumpers lose their IP20 rating for touch protection because the jumpers introduce exposed metal to the circuit.

Plug voltage meters into the built-in sockets to confirm the voltage is right for your application. You can also test and troubleshoot circuits without removing any wire. Push, turn, and release the knob to break your connection. When the knob is released, stick a wire through the hole so you can't accidentally reconnect the circuit—similar to a lockout tag.

Run your thermocouple wire into these blocks so no signal is lost or destroyed. The metal in the terminals is compatible with multiple thermocouple wire types.
