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 and temperature changes. Add as many circuits as you need with these terminal blocks and accessories; blocks mount side-by-side on DIN 3 rail.

Blocks with fuse holder allow inline fuse wiring to protect components and wires from short-circuit damage.

Use blocks with disconnect tab for testing.

End covers fit on the open side of a block to prevent accidental contact with a live circuit.

End stops mount at the end of a group of blocks to prevent movement.

Adjacent jumpers connect terminals on adjacent blocks of the same width. Alternate jumpers connect terminals on two blocks of the same width, skipping a block in between.

Numbered marker cards include two of each number (1-50).

Note: Prices are 15% lower when you buy 25 or more of the same size.

Recessed terminals prevent accidental contact with a live circuit.

Blocks with screw terminals provide a more secure connection than blocks with grooved-clamp terminals. Use with ring terminals, spade terminals, or stripped wire; you can attach them without removing the screw.

Use blocks with grooved-clamp terminals with stripped wire. The grooved clamps hold the wire tight to prevent it from moving.

Add as many circuits as you need with these terminal blocks and accessories. The terminal blocks clip onto DIN 2 rail. Terminal blocks, end covers, and end stops meet IP20 to protect connections from objects larger than 12.5 mm, such as fingers.

Spring-clamp terminals make wire installation faster than screw-clamp terminals. Push the wire into the spring clamp for a secure connection that withstands vibration.

End covers fit on the open side of a block to prevent accidental contact with a live circuit.

End stops mount at the end of a group of blocks to prevent movement.

Jumpers connect terminals on adjacent blocks of the same width. Noninsulated jumpers can be cut to size.

Use DIN rail adapters to mount blocks to DIN 3 rail. Two adapters per block are required, except the two-circuit blocks need only one adapter.
