2-Pole Screw Terminal Block (AC Rated) - Pack of 2

The 2-Pole Screw Terminal Block (AC Rated) is a fundamental building block for any electrical or electronic assembly that requires a secure, removable wire connection. Sold as a pack of 2, these compact green connectors are designed for PCB mounting with a standard 5mm pin spacing, making them compatible with a wide range of printed circuit boards, prototype boards, and power distribution modules. How It Works: Each pole features a metal screw clamp that, when tightened, presses down on a stripped wire inserted into the terminal. This creates a gas-tight, low-resistance connection that is both mechanically strong and electrically stable. The terminal block supports wire gauges from 26 AWG to 16 AWG, and the screw mechanism allows for quick wiring changes without soldering. Rated for 250V AC and 16A, these blocks are suitable for mains-powered applications and general AC signal routing. Key Features: The block is manufactured from high-temperature-resistant polyamide (nylon) plastic with nickel-plated brass screws and tin-plated copper alloy conductors. The green color is a standard industry identifier for live/line connections, while the open-top screw design allows easy access with a standard screwdriver. Through-hole solder pins (0.5mm thick) provide strong mechanical anchoring to the PCB. The 5mm pitch matches standard breadboard and perfboard spacing for prototyping. Typical Projects: Use these terminal blocks in AC power input/output stages of power supplies, motor drivers, lighting controllers, temperature controllers, relay boards, and industrial automation panels. They are also excellent for educational electronics labs, inverter projects, and home automation hubs where reliable AC wiring is required. The pack of 2 gives you a spare or allows you to build two identical circuits. What's in the Box: 2 x 2-pole screw terminal blocks (green, 5mm pitch). No wires or screws are included. The terminals accept solid or stranded wires from 0.5mm² to 1.5mm². For best results, strip wires to 6-7mm before insertion.
