DINnectors™ (DIN Rail Terminal Blocks)

Faster installation than standard screws

Easy clamp-system connection

Maintenance free

Meets UL, CSA and IEC standards

Jumper system design improvements have been made to the Screwless series of terminal blocks to add to the quality and reliability of the products.

Screwless jumpers and associated terminal blocks are being discontinued and replaced with the redesigned -A series.
The new products are identical in width and height and have the same sizes as the original line, with the only change being the design of the jumper system.
The new �A series is designed to work in current and future applications.

Screwless terminal blocks save time and money. They offer a quick and easy clamping system that is secure and maintenance free. Just push the spring clamp, insert the wire and release.

	Screwless Feed-Through DINnectors Single level (feed-through) terminal blocks provide the means to connect two wires together, and are available in sizes suitable for up to 8 AWG wire. DN-Q series from $24.50 (50 pieces)		Screwless Double-level DINnectors Double-level terminal blocks offer twice the wiring density of feed-through blocks. Versions with internal jumpers, LEDs and diodes are available. DN-QD series from $36.00 (25 pieces)
	Screwless Common Point DINnectors The two-to-two version allows multiple wires to be connected together by way of multiple spring-clamps. LED and diode variations are also available in this style. DN-Q12 series starts at $21.00 (25 pieces)		Screwless Ground DINnectors Ground terminal blocks are used to mechanically and electrically ground wires to the DIN rail to function as a ground bus bar. Ground blocks are green / yellow per international standards. DN-QG series from $19.00 (10 pieces)
	Screwless Disconnect DINnectors The DN-QKBD12 disconnect terminal block allows fast circuit disconnection without rewiring by means of a pivoting, insulated �knife-blade.� DN-QKBD12 is $43.50 (25 pieces)		Screwless Plug-In DINnectors Single and double level DN-QEMXxx screwless plug-in terminal blocks with spring terminals accept all DN-xxPLUG Euro plugs.

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.
