# Screw Terminal Block: 3-Pin, 5 mm Pitch, Side Entry (4-Pack) **Type:** Product page · **SKU:** POLOLU-2441 · **Brand:** [Pololu](https://core-electronics.com.au/brands/pololu-australia) **Page:** https://core-electronics.com.au/screw-terminal-block-3-pin-5-mm-pitch-side-entry-4-pack.html ([markdown](https://core-electronics.com.au/screw-terminal-block-3-pin-5-mm-pitch-side-entry-4-pack.html.md)) These side-entry screw terminal blocks have a pitch of 5 mm (0.197″). Each block has three terminals for the stripped ends of 22 – 14 AWG wires, and units can slide together to make longer strips. They are rated for 250 V, 16 A (UL) and ship in packs of four. ## Pricing - **Price:** $4.10 (inc GST) — $3.73 AUD, exc GST - **Quantity discounts:** 10+ $3.58 (exc GST) · 25+ $3.46 (exc GST) ## Availability & dispatch - In stock, ships same business day if ordered before 2PM (Australia/Sydney). - We can dispatch 2 today, and up to 250 more in 4–7 days. ## Description These terminal blocks have terminals that hold and release wires through the simple adjustment of a screw, allowing you to easily make temporary connections to a PCB. The 2-pin and 3-pin units each feature a ridge on one side and a slot on the other, which lets them slide and lock together to form arbitrarily long strips with a pitch of 3.5 mm or 5 mm. Each terminal block is available in two orientations: side-entry and top-entry. The following short video gives a quick overview of how to install these terminal blocks onto Pololu's boards: **Details for item #2441** This product is a four-pack of 5mm-pitch, three-pin, side-entry terminal blocks.
