Push-In DIN Rail Terminal Blocks

Push-in DIN Rail terminal blocks are the quickest way to wire a panel: a solid or ferruled conductor is pushed straight into the terminal and held by a steel spring, with a release lever to take it out again. No screwdriver, no torque setting and no re-torquing after thermal cycling or vibration. The 161 blocks listed here are Dinkle parts, under Dinkle part numbers.

What is in this range

• Feed-through blocks – 36 parts, single level, bi-level and three level, for straight-through connections at the highest density per inch of rail.
• Grounding blocks – 41 parts, bonding the conductor to the DIN Rail for protective earth.
• Fuse blocks – 26 parts, taking a fuse in the terminal itself so a circuit can be protected without a separate holder.
• Disconnect and disconnect-test blocks – 20 parts, including bi-level versions, for isolating or test-probing a circuit without unwiring it.
• Plug-in connection blocks – 8 parts, where the field wiring unplugs as a unit for service or panel swap-out.
• Diode and component blocks – 13 parts, with the diode or component built into the terminal.
• Sensor blocks – 6 parts, for two, three and four wire sensor terminations.
• Potential collective and distribution blocks – 9 parts, for building a common potential point in the panel.

Push-in, screw clamp or spring clamp

Push-in is the fastest to wire and needs no maintenance, and it suits ferruled stranded wire and solid conductors. Stranded wire without a ferrule generally needs a screw or spring clamp instead. Screw connection remains the choice where an inspection regime calls for a torque record; spring clamp sits between the two, accepting bare stranded wire at a constant force. All three connection styles are listed under DIN Rail Terminal Blocks, along with stud connection for heavy current and busbar blocks for distribution points.

Selecting a block

Each part page gives the rail width per block, the voltage and current rating, the conductor range and the part number as the manufacturer publishes them. Send us a schedule or a panel drawing and we will work the quantities and the accessories – end brackets, end covers, jumper bars and marker strips – against it. If you are cross-referencing from another manufacturer’s block, send the part number: we compare the published dimensions, wire range and ratings line by line and tell you plainly whether it interchanges or only comes close.
