DINnectors Screwless Disconnect Terminal Blocks Overview

Why go screwless?

Speed: On average, screwless connections can be made in half the time as screw type connections, cutting installation labor costs in half.
Ease: No need for twisting and turning screws, so screwless terminal blocks are much easier on the installer's hands and arms. Also, wiring from the top of the terminal blocks allow installers to accurately and reliably see the wire fully inserted into the spring clamp.
Safety: Never have a problem with loose connections from loose screws again! Meets the same UL, CSA, and IEC standards as screw-type terminal blocks.
Reliability: Screwless terminal blocks provide secure connections.
Maintenance-free: The screwless springclamp conforms to the wire with constant tension, making it maintenance-free.

Are there any trade-offs?

Unless you need to clamp multiple wires to the same connection point, the answer is no. If you do, then there may be a slight trade-off in requiring more panel space than with screw terminal blocks.
- Unlike screw terminal blocks, screwless terminal block spring-clamps are designed to clamp a single wire only.
- This is why multiple versions exist like the "one-to-two" or "two-to-two." These versions allow multiple wires to be connected together via multiple spring-clamps.
