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 $23.00
(50 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 $34.25
(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 $17.50
(10 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 atarts at $21.75
(25 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 $34.00
(25 pieces) |
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 vibration-proof 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.
