V-Type Terminal Blocks: Compact and Economical Connections
By the Antong Engineering Team · Reviewed August 2026 · 9 min read
Selecting the right V type terminal block requires more than matching a familiar catalog name. Products in the same category can differ in current path, conductor interface, material, dimensions, mounting and approval conditions.
For lighting OEMs and small appliances, that distinction affects initial design, purchasing, assembly and later maintenance. This guide follows the original brief from construction through ratings, applications and practical checks so the same evidence can support the RFQ, sample approval and inspection record.
From more than 35 years of manufacturing terminal blocks, the consistent lesson is that reliability comes from matching the complete application rather than one attractive number. Antong SP005 V-type catalog examples use PE housings and list model-specific wire, current and voltage values from 2.5 mm² upward.
Quick answer: V-type terminal blocks are compact, economical fixed strips commonly used where cost and panel space matter. Their V designation describes a product-body family rather than a universal standard, so buyers must match the exact dimensions, material, conductor, wire range and tested ratings.
In this guide
What Is a V-Type Terminal Block?
V-type terminal blocks are compact, economical fixed strips commonly used where cost and panel space matter. A useful definition also identifies the boundary of the category, separating a V-Type Terminal Block from similar-looking connection or mounting systems.
V-shaped compact body
Measure total installed space and labor rather than unit size or price alone. Higher density can increase heat, routing effort and service time, while a more expensive interface can reduce assembly or replacement cost. Do not copy the value from a neighboring series unless the manufacturer documents the same construction and approval.
Economical construction for high-volume use
Current-bar cross-section, clamp geometry, insulation and mounting all contribute to the finished terminal. A change to one component can alter rating, fit or service life. Do not copy the value from a neighboring series unless the manufacturer documents the same construction and approval.
Typical Applications
Application examples help narrow the product family, but an industry name is not an electrical rating. Translate each use case into current, voltage, conductor, temperature, vibration, enclosure and service requirements.
Lighting fixtures
One application can contain both low-energy signals and high-power circuits. Divide the wiring into duty classes and select each terminal from the conditions at that connection point. A compact body reduces material and space but does not remove requirements for creepage, torque and temperature rise.
Small home appliances
The application is a starting condition, not a rating. Translate it into current, voltage, temperature, vibration, enclosure, servicing and certification requirements before choosing a product family. Keep the evidence with the drawing and sample record so purchasing cannot substitute a similar-looking part.
Power supplies
Use the point to eliminate unsuitable variants, then confirm the remaining choice on the exact datasheet and sample. Similar naming is not evidence of equivalent construction. Keep the evidence with the drawing and sample record so purchasing cannot substitute a similar-looking part.
V-Type vs U-Type vs H-Type
| Family | Typical positioning | Selection check |
|---|---|---|
| V-type | Compact and economical fixed strip | Exact body dimensions and rating |
| U-type | Recessed fixed multi-pole family | Material, conductor and mounting pattern |
| H-type | Fixed H-profile family | Wire entry, mounting and certification |
These names are supplier-family conventions rather than universal IEC shape classes.
V-Type vs U-Type vs H-Type
The comparison under v-type vs u-type vs h-type is most useful when every option is judged against the same circuit and installation conditions. Compare tested ratings, fit, labor and service requirements rather than one isolated feature.
Size, cost, and current rating comparison
Compare the alternatives on the same axes: function, current path, conductor, mounting, rating, service method and approval. Judge both alternatives under the same load, conductor, mounting and service conditions. Similar appearance or one shared dimension does not establish equivalent function or approval. Antong SP005 V-type catalog examples use PE housings and list model-specific wire, current and voltage values from 2.5 mm² upward.
When V-type is the right choice
Make the choice only after the operating conditions and service objective are quantified. Judge both alternatives under the same load, conductor, mounting and service conditions. Similar appearance or one shared dimension does not establish equivalent function or approval. Record the accepted condition in the terminal schedule so installers and inspectors use the same basis.
Material and Ratings
This section explains material and ratings and identifies the values that need to be fixed on the drawing, datasheet or RFQ. A change in one value can alter fit, rating or service access.
PE insulation, brass/steel conductor options
Separate the material family from the exact alloy or resin grade. Conductivity, strength, temperature, flame behavior and corrosion performance can change with grade, plating, molding and finished geometry. Do not copy the value from a neighboring series unless the manufacturer documents the same construction and approval.
Current and voltage ratings
Treat the value as a tested thermal condition rather than a number inferred from body size. Keep it paired with the declared conductor, ambient, grouping and certification system, then apply required derating. A compact body reduces material and space but does not remove requirements for creepage, torque and temperature rise.

FAQ: Frequently Asked Questions
What is a V-type terminal block used for?
A V-type terminal block is commonly used as a compact fixed multi-pole screw strip in lighting, appliances and power supplies. The V label is manufacturer-specific, so selection must follow the exact drawing and ratings.
Are V-type terminals suitable for lighting?
Yes, where its current, voltage, wire range, operating temperature, flammability and mounting match the luminaire. Lamp and driver heat must be included in the temperature assessment.
How do V-type terminals compare to U-type?
V-type products generally target compact, economical layouts, while U- and H-type families offer different body and mounting geometries. Compare exact models rather than assuming a universal ranking.
Next Steps: Choosing the Right Terminal Block
Turn the guide into a short specification before requesting a quotation. Record the exact function, conductor, electrical ratings, dimensions, mounting, environment, accessories and destination-market approvals, then evaluate a sample in the real assembly.
Browse relevant products — compare complete terminal blocks and connectors catalog and feed-through terminal blocks.
Request the full catalog and drawings — keep the exact item number, revision, dimensions, ratings and accessory list together.
Evaluate production-representative samples — use the actual wire, ferrule or lug, tool, mounting and enclosure conditions.
Send a complete RFQ to engineering — include current, voltage, conductor, environment, quantity, approvals and any OEM/ODM requirements.
Antong has manufactured terminal blocks since 1989, operating a 55,000 m² production facility with ISO 9001 quality management and shipping to 70+ countries. Product parameters and certifications vary by exact model; request the current datasheet and approval evidence before releasing the bill of materials.
