DINnector DN series screwless disconnect terminal blocks enable single-wire circuits to be opened or tests to be performed while the system is powered. Disconnect terminal blocks are available in a pivoting knife-blade style and accommodate wire sizes up to 12 AWG.
Screwless Knife-Blade Disconnect Terminal Blocks and Accessories
DINnectors™
(DIN Rail Terminal Blocks)
Screwless terminal blocks save time and money. They offer a quick and easy clamping system that is vibration proof and maintenance free. Just push the spring clamp, insert the wire and release.
- Faster installation than standard screws
- Easy clamp-system connection
- Maintenance free
- Meets UL, CSA and IEC standards
Screwless Disconnect Terminal Blocks
The DN-QKBD12 disconnect terminal block allows fast circuit disconnection without rewiring. This model provides circuit disconnection capability by means of a pivoting, insulated “knife-blade.”
DINWhy 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.
