Terminal Blocks
Single-Row Feed-Through Terminal Blocks
A single-row barrier feed-through terminal block is a type of electrical connector used to safely and neatly join or pass wires through a panel, enclosure, or mounting plate.
Barrier Terminal Block
- A barrier terminal block has insulating barriers (walls) between each terminal to prevent accidental short circuits between adjacent connections.
- These are common in power distribution and control panels because they improve safety and reduce wiring mistakes.
Feed-Through Design
- “Feed-through” means the block allows a conductor (wire) to pass straight through from one side to the other, making it easy to connect incoming and outgoing wires.
- Typically, you insert a wire into one side and connect it with a screw or spring clamp, and then another wire into the opposite side.
