Product Details
1 Characteristics of PT terminals
The Push-in direct connection technology reduces insertion forces by up to50 percent and enables tool-free wiring, allowing conductors to be insertedeasily and directly.
Made from engineering-grade nylon PA66 with a brass screw.The Push-in connection terminal blocks are characterized by easy and tool-free wiring of conductors with ferrules or solid conductors.The compact design and front connection enable wiring in a confinedspace.
2 Characteristics of PT terminals
The robust connection provides reliable electrical contact, making it suitablefor industrial environments.
The insulated housing helps reduce the risk of short circuits and electric shock.
Installation and maintenance are relatively easy, with faster wiringreplacement, expansion, and troubleshooting.
Highly modular, it is suitable for DIN rail control cabinets, resulting in neaterwiring.
It is generally more stable in vibration environments than simple splicingmethods, making it suitable for industrial automation applications.
PT direct-plug self-locking wiring method
PT self-locking through-hole terminals are generally wired as follows: First,strip the appropriate length of insulation from the wire. Then, insert asingle-strand hard wire or a multi-strand wire with a pre-crimped cold-pressed head directly into the terminal’s wiring hole.
The wire will be automatically clamped and maintained stably by theinternal spring/self-locking mechanism. To disconnect the wire, press theterminal’s release mechanism and then pull out the wire.

Common problems with PT direct-insertion self-locking terminal blocks
How to buy PT through-hole terminal blocks without making a mistake?
Four things you need to confirm first:
What type of wire are you using? Wire gauge is crucial. For example, some PT terminals support conductors ranging from .14 to 4 mm2 or similarspecifications.
What curentoltage do you need to handle? Ratings vary significanty between models. Some PT terminals are rated up to 24A/80o V,whileothers are only suitable for lower currents.
Where are you installing them? Many of these terminals are designed for 35 mm DIN rails and cannot be simply screwed on.
Do you need screw-in or tool-ess connections? PT series terminals are commonly pushin, suitable for quick wiring ifyou require a moretraditional crimp/screw method, you need to rephrase your question.
What should I confirm before buying PT through-hole terminal blocks?
You can first confirm these four pieces of information yourself:
What wire thickness do you need? For example, 0.14-4 mm2, 0.5-6 mm2, etc.
What current and voltage does i need to withstand? Different models vary greatly, so don’t just look at the appearance.
Where does it need to be installed? Many PT terminals are mounted on 35 mm DIN rails.
Do you need screw-type or tool-less type? The PT series usually leans towards a push-in type, which is faster for wiring.
Can this product be used with jumper plates, end plates, and marking strips?
For this PT direct insertion self-locking terminal block product, our factory provides matching accessories, such as: baffies, marking strips, fixing
components, and pluggable bridging components.
What should I ask most when buying UK terminal blocks for the first time?
Is this an original part or a compatible part?
Is it suitable for my intended use, such as control cabinets, equipment wiring, or home wiring?
Different scenarios call for different selections.
control cabinets prioritize stability, modularity,and ease of maintenance; home applications prioritize simple installation, and internal wiring ofequipment prioritizes temperature resistance and vibration resistance.
How to determine if a seller of PT through-hole terminal blocks is reliable?
If a seller provides a professional answer, they will usually give you the following information directly:Specific model number, not just “PT terminal.
Wire gauge range, not just “universal”.
Rated voltage and current.
Mounting method, such as compatibility with DIN rails.
Whether there is a datasheet/specification.
Is this a push-in type or a screw type?
PT series connectors are commonly push-in type, offering advantages such as quick wiring and easy maintenance.
If you prefer traditional screw-type wiring, I recommend choosing UK or TC connectors; we sell both.
