Add as many circuits as you need with these terminal blocks and accessories. The terminal blocks clip onto DIN 2 rail. All blocks are rated UL 94 V-0, so they meet flammability standards. They’re IP20 rated to protect connections from objects larger than 12.5 mm, such as fingers.

Spring-clamp terminals make wire installation faster than screw-clamp terminals. These wire connections also stand up to vibration and temperature changes. Insert a slotted screwdriver to release the spring clamp and then push your wire into place.

Blocks with a fuse holder protect components and wire from short-circuit damage by enclosing the fuse.

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 keep them in place.

Jumpers connect circuits between blocks to simplify wiring and leave terminals available to connect equipment. They’re adjacent jumpers, so they connect terminals on adjacent blocks of the same width. Noninsulated jumpers can be cut to size.

Marker cards fit into built-in label holders on the blocks.
