Product Details
Structure of a UKK single-level junction box
- Rail-mount base: Designed to snap onto a DIN rail for easy installationand removal.
- Input terminal: Usually one main input port for connecting the mainpower supply.
- Output terminal: Typically one input with multiple outputs, used todistribute one main wire into several branch wires.
- Conductor: Usually made of copper alloy or nickel-plated copper,responsible for conduction and power distribution.
- Insulating housing: Commonly made of PA nylon or similar insulatingmaterials, featuring flame resistance, heat resistance, and impactresistance.
- Transparent cover: Makes it easy to check the internal wiringcondition; some designs are openable or hinged.
Internal structure and materials
UKK terminal blocks typically use flame-retardant PA66 insulated housings,with internal conductive components mostly made of brass and nickel-plated. The fastening screws are generally made of high-strength steel withelectroplated surfaces to balance insulation safety, conductivity, andmechanical strength.
This material is resistant to deformation or releasing toxic fumes under hightemperatures or short circuits, effectively isolating ignition sources andpreventing faults from escalating into fires.
Flame retardant rating and mechanism
UKK terminal housings typically meet the V-0 flame retardant standard,meaning they self-extinguish within 3 seconds of the ignition source beingremoved after contact with a flame, without dripping burning material orcausing further spread.
This material is resistant to deformation or releasing toxic fumes under hightemperatures or short circuits, effectively isolating ignition sources andpreventing faults from escalating into fires.
UKK junction box wiring method
UKK typically uses DIN rail screw terminals/branch terminals. Theconnection method is very straightforward: first, disconnect the power, stripthe wire ends, insert them into the terminal crimping position, and thentighten the screw to secure them.
If it is a flexible wire, it is usually more stable and safer to crimp the cold-pressed end first and then connect it to the terminal.

Common problems with UK series universal screw terminal blocks
Are UK terminal blocks easy to operate?
This type of terminal block is commonly known as a spring terminal block lever-type quick-connect terminal block, or ral terminal block. Its keyselling points are screwles operation, quick wiring and reusable assembly and disassembly, making it suitable for wiring scenarios in distributioncabinets, control cabinets, lighting, and equipment.
Will the UK terminal blocks overheat and burn out?
Under normal use, i wil not cause overheating. but f there is poor contac,. oose screws overoad of the selected wire, or mismatch between wrediameter and terminal specifications, i may cause overheating, and in severe cases, it may burn black or even burn out.
What scenarios are UK terminal blocks suitable for?
Commonly found in:
Control cabinets.
Distribution boxes.
Automation equipment.
Industrial control systems.
Electrical installation scenarios requiring neat wiring.
What should I ask most when buying UK terminal blocks for the first time?
The most crucial factors are:
What wire diameter is required?
Rated current.
Rated voltage.
Applicable temperature range.
Does the flexible wire need to be terminated?
Is it suitable for DIN rail mounting?
