Product Overview
Single Pole One Inlet Ten Outlet carries one incoming feeder out to ten numbered branch circuits from a single pole of 35 mm DIN rail.
It fits packaged industrial distribution boards and building automation panels, where one supply is shared across a run of ten small loads and ten separate blocks would each take a slot on the rail.
The block is judged on grip. A pressure plate under every screw presses the conductor across a flat face, so all ten positions hold with the same force instead of one conductor taking the strain while its neighbour sits loose, and integrated lock washers hold that tension through vibration and cabinet heat cycles - which is where loose joints, and the sparking that follows, begin.

Core Advantages
Four points decide how a ten-way block behaves in service.
Even Force At Every Position
The plate presses the conductor over a flat face rather than at a single point, so position one and position ten clamp alike.
Lock Washers Under The Screws
Integrated lock washers hold the joint through vibration and cabinet heat cycles, so the torque set at handover is not the last time the screws are right.
One Pole For Ten Branches
Ten branches leave a body one pole wide, so the rail is spent on devices rather than on branching, with no jumper wiring between blocks.
Numbered, One Entry Each
Each outlet has its own conductor entry and its own number, so a run is traced from the position, not from a tag that may have come away.
Wire Cage Terminal vs Traditional Brass Terminal
The two clamps differ in where the screw's force finally lands.
| What Changes | Pressure-Plate Screw Clamp On This Block | Traditional Brass Terminal Strip |
|---|---|---|
| Where clamping force lands | A flat plate spreads it across the conductor face | Concentrated at the screw tip or a single set point |
| Force across ten positions | Identical plate and washer travel at every position, so the row clamps evenly | Each screw set by feel, so force varies along the strip |
| Under thermal cycling | Lock washer holds tension as the cabinet heats and cools | Brass relaxes and the joint returns for re-torquing |
| A conductor that works loose | Even grip removes the usual cause of it | One loose conductor arcs while the rest of the strip still reads fine |
| Torque to apply | 0.8–1.0 N·m, published for the block | Not published; set by experience |
| Tracing one circuit | Numbered position with its own entry point | Shared strip, found by tag |
| Changing one branch | One position opens without disturbing the others | Opening a position mid-strip disturbs the circuits either side |
| Contact surface | Tin plating over copper | Bare brass |
Professional Production Process
Six stages per batch, released on recorded results rather than on appearance.
Copper stock cut and punched to the released drawing.
Sharp edges removed and drilling burrs dressed in the press.
Parts degreased, then tin-plated to the specified thickness.
ABS housings moulded and checked against UL94 V-0.
Plates and lock washers fitted, then checked for even travel across all ten positions.
Routine electrical test recorded per batch - 500 V DC insulation check, 2.5 kV AC withstand for one minute.
Material & Surface Treatment Options
Settle both choices on the drawing before a batch is released.
Flame-Retardant ABS Housing
The housing is published as flame-retardant ABS rated UL94 V-0; one model in the same series carries a glass-filled PA66 body instead, so the grade is worth fixing before the order is placed.
Tin-Plated Copper Conductors
Contacts are high-purity copper with a tin plate, which keeps the contact face free of the oxide film bare copper builds up in a warm cabinet and that quietly raises resistance at a joint.
Application Scenarios
Three cabinet types carry ten parallel branches off one supply.
Industrial Distribution Cabinets
Packaged boards where one feeder serves ten control, indication or metering branches, each brought to the same published torque - which is what keeps the row reliable after a few hundred heat cycles.
Building Automation Control Cabinets
BMS and control panels that fan one supply out to ten field circuits; numbered positions and one entry point per outlet let a commissioning engineer work down the row and trace a fault to a position.
Solar Combiners And Lighting Control
A photovoltaic combiner stringing ten inputs, an LED lighting panel switching ten circuits from one feed, and commercial ten-branch distribution panels - the framing this product has been sold under.
Frequently Asked Questions
Q: What is a single-pole ten-outlet distribution block used for?
A: It divides one incoming feeder into ten branch circuits from a single pole of DIN rail, for industrial distribution cabinets, building automation control cabinets, photovoltaic combiners and commercial ten-branch panels.
Q: How does the block keep all ten conductors equally tight?
A: A pressure plate under each screw presses the conductor across a flat face, so every position clamps with the same force, and a lock washer holds that tension through vibration and thermal cycling. Joints that loosen and arc usually start with a conductor that never carried its share of the load.
Q: What are the electrical ratings and wire ranges?
A: 80 A continuous total input at 400 V AC, with 6 A at any one outlet. The inlet accepts 6–50 mm² and the outlets 1.5–10 mm², solid or stranded copper, tightened to 0.8–1.0 N·m. Ten outlets at 6 A sum to 60 A.
Q: How is the block mounted and identified?
A: The body snaps onto standard 35 mm DIN rail without tools. Each outlet has its own numbered position and entry point, so circuits are labelled and maintained by position.
Q: Can the block be adapted to our drawing, and how small can the first order be?
A: Labelling, mounting detail and the circuit count are produced to your drawing, and OEM or ODM is open on volume. The smallest first order is 10 pieces; standard builds run 7–10 days, custom builds 15–20. Send the drawing and the quotation comes back within 24 hours.
