Sized to fit non-UL Class Midget Fuses, these fuse blocks are suitable for switchboard panels, small motors, and transformers. The covered terminals prevent contact with live electrical circuits.

Designed for the solar industry, these fuse blocks can handle the requirements of high-voltage DC applications. The covered terminals prevent contact with live electrical circuits.

Add as many circuits as you need with these terminal blocks and accessories. The terminal blocks clip onto DIN 3 and DIN 1 rail and can be removed without disrupting adjacent blocks. All have screw-clamp terminals for a secure connection, reducing the chance of wire disconnecting due to vibrations, pulls, or snags. Blocks that meet IP10 shield connections from objects larger than your hand; those that meet IP20 protect against objects larger than your fingers.

Blocks that are 51.5 mm or 63.5 mm high have a single circuit with multiple screw-clamp terminals, so they save space on DIN rail.

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

Blocks with a disconnect tab or knob easily disconnect a circuit without needing to remove installed wire. Use them for testing. Disconnect knobs have a push-button with a through hole, so they can be sealed with wire when they’re disconnected, similar to a lockout tag. This reduces the risk of accidentally connecting the circuit. A test socket lets you try out your circuit. Insert a test plug (sold separately) into the socket, then use a voltage meter to check.

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. Those rated IP20 provide additional protection from objects larger than your fingers.

Jumpers connect terminals on adjacent blocks of the same width. Bar jumpers screw down into designated sections on terminal blocks. You can cut them to size. Where listed, end covers should be used on the outermost blocks in the connection. Lateral jumpers are connected to blocks in place of a wire or in addition to a wire at the screw-clamp connection terminal points. Insulated jumpers eliminate the risk of your finger coming into contact with a live circuit, so they’re touch safe.

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.

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).
