Screw Connection

Screw connection DIN rail terminal blocks: 102 Dinkle blocks for 35 mm rail, from 0.5 A sensor blocks to 370 A power blocks, taking wire from 28 AWG to 4/0 AWG. A captive screw clamps the conductor against the current bar — the long-established termination for control panel field wiring, re-terminable with a plain screwdriver.

Block types in this range

• Feed-through blocks in single level, bi-level, three level and four level bodies
• Grounding (PE) blocks in green-yellow, clamped to the rail
• Disconnect, knife disconnect and disconnect-test blocks
• Fuse terminal blocks and diode terminal blocks
• Sensor blocks and component blocks
• Plug-in connection blocks
• Panel mounting blocks with a threaded flange, for chassis work off the rail

Ratings across the range

UL rated voltage 24 V to 1000 V, most commonly 300 V and 600 V, and UL rated current from 0.5 A to 370 A. UL wire range 28 AWG to 4/0 AWG, and 300 to 500 kcmil on the largest bodies; IEC 0.14 to 240 mm². Screw threads M2.5 through M10, with stripping length called out per part, from 6–8 mm on the smallest blocks to 35–40 mm on the largest. Bodies are polyamide, UL94 V-0, rated −40 to 120 °C, and mount on TS-35, TS-35/15 and TS-15 rail.
