Barrier Terminal Block 4 Pin with Cover 300V/25A 9.5mm Pitch
The 4-pin barrier terminal block with cover is engineered as a reliable interface for connecting multiple wires securely in an electrical panel or PCB setup. Its barrier style provides physical segmentation between each pin, enhancing safety by reducing the chances of short circuits. The block is built from a durable insulating material that resists heat and electrical stress, with a protective cover (sometimes lid or flap) that shields the conductors and screws from accidental contact or debris.
Each of the four connection points (pins) is spaced at 9.5 mm, allowing enough separation for robust wires to be attached without risk of interference. The design supports firm clamping of wires via screws (or screw terminations) which ensures solid electrical contact and minimizes loosening over time. The metal parts, often brass or tin-plated, conduct well and resist corrosion, while the insulating body holds everything securely.
The cover contributes both mechanical protection (protecting from accidental touches or dust) and sometimes improved safety compliance in environments where exposed metal parts are undesirable. Overall, this terminal block merges mechanical robustness with safe electrical isolation, making it suitable wherever moderate currents (up to about 25 A) and mid-level voltages (around 300 V) must be safely distributed among multiple wires while maintaining good organization and protection.
Features:
- Has a protective cover/flap over the connection screws.

- Four separate connection points (4 pins).
- Screws for wire clamping enabling secure and tight wire connections.
- Tin-plated or corrosion-resistant metal contacts to maintain good conductivity.
- Mountable on PCB (wire-to-board) style design.
