Terminal Block Manufacturer in China
We manufacture terminal blocks in-house for distributors, panel builders and OEM brands that buy in volume. Our range covers barrier and euro strips, DIN rail, PCB, pluggable and power distribution blocks.
As a terminal block supplier since 1997, we ship worldwide and can add your brand through private labeling or custom marking. Our minimum order value is US$5,000 per SKU, so quantity depends on the model you choose.

Barrier Terminal Block
Panel · screw
Euro-style barrier strips from 3A to 150A, 12 poles, with recessed screws and wire protectors. Cut to length for lighting, HVAC and control wiring.
DIN Rail Terminal Block
TS35 / TS15 rail · screw, spring, push-in
Rail-mount blocks in screw, spring clamp, push-in and ground/PE styles for TS35×7.5, TS35×15 and TS15 rails. Built for control cabinets and automation panels.
Pluggable Terminal Block
PCB · spring clamp / plug-in
Two-part plug and header blocks that let you disconnect a board without rewiring. Tool-free spring clamp versions suit HVAC, inverters and control boards.
PCB Terminal Block
PCB · screw
Screw-type blocks soldered straight onto circuit boards for wire-to-board connections. Available in several pitches and pole counts for electronics makers.
Feed-Through Terminal Block
DIN rail · screw
Single-level blocks that pass one conductor through to another in a panel. The simplest way to join field wiring to internal cabinet wiring in rows.
Distribution Terminal Block
Panel / rail · screw
Splits one incoming power cable into several outputs inside switchboards and enclosures. Keeps power distribution tidy, covered and easy to inspect.
Busbar Terminal Block
Panel · screw
Busbar-style blocks that share one conductor across multiple connection points. Used for neutral, earth and power bridging in distribution boards.
Neutral Terminal Block
Panel · screw
Brass neutral and earth bars that collect return and ground conductors in consumer units and panels. Available in multiple way counts and mounting styles.
Motor Terminal Block
Motor housing · stud / screw
Terminal boards that connect supply cables to motor windings inside the terminal box. Built for secure, vibration-resistant connections in electric motors.
Ceramic Terminal Block
Panel · screw
Ceramic-body blocks that connect wires in high-temperature areas where plastic housings would not last. Available in enclosed and exposed terminal versions.
Marine Terminal Block
Panel · screw / stud
Terminal blocks for boat and marine electrical panels, with covered designs that protect connections from moisture and accidental contact on board.
Quick connectors: DF-CH2 lever connector · DF-PCT lever connector (32A / 250V) · 3-pole push-on connector. See quick connector specs

Our Factory: In-House Production Since 1997
We make our terminal blocks in our own facility in Wenzhou, China, instead of reselling from other workshops. That means we control the housing moulding, the metal parts and the final assembly.
For you, buying from the terminal block manufacturer directly means one contact for specs, samples and delivery, and no distributor margin in between.

OEM & Custom Terminal Blocks
What You Can Customize
If you sell terminal blocks under your own brand, we can produce them with your logo, marking and packaging. Custom work starts from one of our existing models, and we confirm what is possible before you order.
Available on request: your logo or brand name on the housing, custom marking and circuit numbering, private label packaging and box labels, free samples for approval.
Needs a technical review first: non-standard colors, non-standard pole counts, new housing or tooling, different electrical ratings or materials.
Contact us for examples of marked and private label parts.
What to send us
- The model: part number, photo or drawing (we can help you pick one)
- Quantity per SKU: each model needs US$5,000 minimum order value
- Your artwork: logo files in AI, PDF or SVG
- Marking position: housing top, side or packaging only
- Approval step: artwork proof, physical sample, or both
Wholesale Supply for Distributors & Bulk Buyers
We supply distributors, wholesalers, panel builders and equipment makers who buy terminal blocks in volume. Buying straight from the terminal block factory keeps your cost down and gives you one contact from quote to delivery.
Our minimum order value is US$5,000 per SKU. Each model has to reach this on its own, so models can’t be combined to meet it. Wholesale sizes include our 10A, 20A and 30A barrier strips. Ask about distributor pricing and send us your product list, so we can quote every model in one go.

Quality & Certificates
Documents for Your Model
Every order is inspected before shipping. Certificates only help when they match your exact part, so we send the documents for the model you’re buying instead of a generic badge.
- Technical drawing: model reference with dimensions
- LVD test report (EN 60947): the models covered and the test standard
- RoHS test report (SGS): product and material scope
- Product datasheet: electrical and dimensional specifications
Test Reports We Hold
Most of our terminal block models are covered by a GTS LVD test report to EN 60947 and SGS RoHS testing. Ask for the report that matches your model.
How to Choose the Right Model
- MountingScrewed to a panel, clipped on a DIN rail, soldered to a PCB, or fitted inside a motor box.
- Current and voltagePick a rating above your maximum operating current, and allow for heat inside closed enclosures.
- Wire size and typeCheck the cross-section (mm² or AWG) and whether the wire is solid, stranded or fitted with ferrules.
- Connection methodScrew clamp for high clamping force; spring clamp or push-in for fast wiring and vibration.
- EnvironmentHigh temperature points to ceramic blocks; boats and damp areas point to marine designs.
- Poles and documentsThe number of circuits, the pitch, and any drawings or test reports your customer needs.
Not sure? Send us a photo or your application details and we’ll recommend a model.
