LDB Series: Up‑Graded Distribution Terminal Blocks from LINKWELL

Building on the proven performance of our classic LK‑80A blue terminal block, the new‑generation LDB series distribution terminal blocks have undergone comprehensive product‑level optimization, bringing greater flexibility, convenience and cost‑efficiency for cabinet‑based power distribution projects.

Both base and upper cover are manufactured from high‑grade flame‑retardant material, delivering reliable safety performance under demanding electrical environments. Two practical accessories are newly added for on‑site wiring identification: phase‑color markers and printable number marker strips.

Multi‑color phase markers allow engineers to quickly identify different phases at a glance. Compatible with both GB and IEC standards, these flexible color labels remove the requirement for custom‑molded housing colors. There is no longer a high minimum‑order quantity barrier for special‑color housings, which significantly cuts overall procurement costs. Digital marker strips support direct marking for circuits and wire numbers, making loop identification neat and intuitive inside electrical cabinets.

Beyond identification upgrades, the redesigned red sliding latch enables tool‑free assembly and disassembly. While inheriting the well‑regarded tenon‑and‑mortise modular splicing and stable conductive performance from previous generations, the new latch drastically boosts working efficiency for multi‑circuit wire distribution inside cabinets.

The LDB product range covers LDB‑80A, 125A, 160A, 200A, 250A, 400A up to 500A models. The modular design supports flexible assembly for 1‑pole, 2‑pole, 3‑pole or 4‑pole power distribution blocks. Fully certified with CE, UL, RoHS and IP20 rating, this series complies with IEC 60947‑7‑1.

Wide Application Scenarios

Engineered to fit diverse high‑growth industrial segments, LDB series distribution terminals serve as reliable power‑branching components across multiple industries:

• Wind Power: Secure power distribution inside wind turbine control cabinets, adapt to harsh outdoor working conditions.
• Solar Industry: For PV combiner boxes and central inverter cabinets, stable large‑current transmission for photovoltaic systems.
• Energy Storage: Energy‑storage container cabinet wiring, handle frequent charge‑discharge current cycles.
• AI & Data Center: Power distribution for server cabinets, guarantee stable power supply for computing hardware.
• EV Automobile: Inside DC charging pile cabinets, reliable branching for high‑power charging equipment.
• Robot Automation: Control cabinet power splitting for industrial robotic assembly lines.
• Electrical Installation: General‑purpose low‑voltage cabinet projects for infrastructure and building electrical systems.

Frequently Asked Questions

Q1: What pain points does the upgraded LDB series solve compared with older‑generation terminals? A: Older‑style terminals required screwdrivers for disassembly, slowing down field wiring work. The new red sliding latch supports tool‑free hand‑operated assembly and removal. In addition, integrated phase‑color markers and number strips eliminate expensive custom housing orders with high MOQ, balancing on‑site identification needs and total procurement expenditure.

Q2: Can LDB terminals meet both Chinese GB and international IEC standards? A: Yes. The interchangeable color marker set supports phase identification under both GB and IEC specifications. Customers do not need to order special‑colored terminal bodies, simply swap markers to match local wiring codes.

Q3: How many poles can LDB modular blocks build? A: Thanks to tenon‑and‑mortise modular splicing structure, users can freely combine single‑pole, two‑pole, three‑pole and four‑pole distribution blocks for different cabinet layouts. Current ratings range from 80A up to 500A to cover low‑voltage large‑current branching demands.

Q4: What certifications are available for the LDB series for global projects? A: LDB carries CE, UL, RoHS certifications with IP20 protection grade. It complies with IEC 60947‑7‑1, suitable for export projects for worldwide markets.
