Product Overview
The Jack Up One Inlet Six Outlet 10 To 35sqmm takes a single 10–35 mm² feeder and spreads it across six branch circuits from one body on a length of 35 mm DIN rail.
It is built for heavy-duty industrial control cabinets and for the tap-off cabinets that sit downstream of a variable-frequency drive, where the supply arrives once and leaves as six outgoing circuits of awkward, large cross-section conductor.
At this size the conductor is usually finely stranded flexible cable, and that is where ordinary terminals struggle. Clamp it under a screw and one of two things happens: the tip splays the strands and shears them, or the conductor beds in loosely and works its way out once the cabinet is warm and vibrating - which is how a joint that tested fine starts to spark.
Each position on this block holds a clamping frame instead. A captive screw lifts into a jacked-up position and carries the frame clear of the entry, so the stripped conductor goes in straight rather than being forced past a half-open clamp. Turn the screw down and the frame descends flat onto the conductor, spreading the force across the full contact face instead of at one point.
Technical Specifications
Two kinds of row appear below. The published rows are this model's own figures; the rest are borrowed from the two-outlet model in the same jack-up range and are marked so, because each of them still needs a confirmation.
| Item | Specification |

Core Advantages
What separates a six-way block that lasts from one that comes back is almost all in the clamp.
Force Spread Across The Face, Not At A Point
The screw never touches the conductor. It drives a frame that comes down flat, so a 35 mm² flexible conductor is held over its full width rather than pinched at one spot where the strands give way.
The Entry Clears Before The Conductor Goes In
Raising the screw lifts the frame clear of the port, so a stiff, large cross-section conductor is inserted straight and stays straight. Nothing is worked in past a partly closed clamp, which is where splayed strands begin.
A Captive Screw That Cannot Go Missing
The screw is retained by the housing at both ends of its travel and stays permanently aligned, so it cannot drop into the cabinet and cannot start off-square. Cross-threading is removed rather than avoided.
Six Branches From One Feeder
Six outlets leave the block on a single DIN rail body, so large cross-section branching happens at the block instead of at six separate terminals joined by six lengths of jumper.
Wire Cage Terminal vs Traditional Brass Terminal
Both clamps take the same conductor. They differ in what the screw finally presses with.
| What Changes | Jack-Up Frame Clamp On This Block | Traditional Brass Terminal Strip |
|---|---|---|
| Where the force lands | A frame descends flat across the conductor face | The screw tip bears on a single spot |
| A finely stranded conductor | Strands are compressed together under the frame | Strands splay sideways and shear at the screw tip |
| Getting the conductor in | The screw is raised and the port clears fully first | The screw is backed off and the conductor is worked past it |
| The screw itself | Captive in the housing at both ends of travel, permanently aligned | Lifts out of the strip; alignment and cross-threading are live risks |
| Clamping force | Published as ≥ 200 N per terminal - series reference | Not published; set by feel |
| Torque to apply | 5–7 N·m, with a positive stop at full clamp | Not published; set by experience |
| Reopening one branch | One position lifts clear without disturbing its neighbours | Opening a position mid-strip disturbs the circuits either side |
| Contact surface | Tin plate over copper alloy | Bare brass |
Professional Production Process
Every batch moves through six stages and is signed off against recorded measurements rather than against how the parts look.
Copper stock cut and formed to the released drawing.
Contact faces dressed and press burrs removed.
Degreasing, then tin plating to the thickness called up on the drawing.
Housings moulded in flame-retardant PC and checked against UL94 V-0.
Captive screws and clamping frames assembled, then every position cycled to confirm the screw lifts and beds without binding.
An electrical check on each batch, filed against the batch number.
Material & Surface Treatment Options
Both choices below are cheaper to settle on paper than after the tooling is set.
Flame-Retardant PC Housing
This model's housing is published as flame-retardant PC at UL94 V-0, while the two-outlet model in the same range uses PA66 at the same rating. Pin the grade down in writing and the ambiguity goes away.
Tin-Plated Copper Contact Faces
Contacts are a high-conductivity copper alloy under a tin plate. With a frame pressing the whole conductor face, that plating is what holds contact resistance steady in a warm cabinet, where bare copper builds an oxide film and the joint begins to heat.
Application Scenarios
Three cabinet types put a heavy feeder and six branches in the same block.
Heavy-Duty Industrial Control Cabinets
Main control cabinets where one 10–35 mm² feeder is shared across six drive, heater or motor branches, each landed with the same frame force and reopened later without disturbing the row.
VFD Tap-Off Cabinets
The application this page leads with: taking one supply off a drive bus and spreading it to six outgoing circuits, where finely stranded flexible conductor is standard and terminal damage to the strands is the recurring failure.
Solar Combiners And Energy Storage Panels
Multi-string photovoltaic combiner boxes, storage racks and large distribution panels - the framing the live page has sold this block under, alongside the metering rollout it references in the field notes.
Frequently Asked Questions
Q: What does the jack-up mechanism actually do?
A: A captive screw lifts into a jacked-up position and holds the clamping frame clear of the entry, so a large finely stranded conductor goes in without being forced. Turning the screw down brings the frame flat onto the conductor, spreading the clamping force across the face instead of pinching the strands.
Q: Will it damage 35 mm² finely stranded conductor?
A: The frame meets the conductor over its full face, so the strands are compressed together rather than cut. On Class 5/6 flexible conductor a cord-end ferrule is recommended, which keeps the strands together at the clamped point and gives the most repeatable joint.
Q: What clamping force and torque does the block develop?
A: Series reference, to confirm: ≥ 200 N per terminal at 5–7 N·m. The screw has a positive stop at full clamp, so it cannot be driven past the designed position, and it stays aligned because it is retained by the housing.
Q: What are the ratings and the wire range?
A: 125 A continuous duty at 400 V AC, over a 10–35 mm² solid or stranded copper range. The 125 A figure is the block's total; the page publishes no per-outlet current, so confirm the branch load you intend to quote. The same series also lists 690 V AC.
Q: Can it be built to our drawing, and how fast is a quotation?
A: Circuit count, housing marking and clamping-frame detail are all made to your drawing, and OEM or ODM is available once the volume justifies it. A first order can start at 10 pieces. Allow 7–10 days for a standard build and 15–20 for a custom one, and send the drawing across - a quotation follows inside 24 hours.
