UKLSG Terminal Block

During a design review meeting, Kevin said:

“TD terminal blocks can also be mounted on DIN rails. So what’s the real difference from UKLSG?”

The senior engineer replied:

“Mounting method is not the key difference. The structural concept is.”

Type 1: UKLSG – DIN Rail System Terminal Block

UKLSG is designed as a DIN rail system terminal block.

Key characteristics:

Designed specifically for DIN rail mounting

Each unit is an independent modular block

Plug-in jumper bars for easy bridging

Full accessory system (end plates, markers, test plugs, etc.)

Strong emphasis on modular system integration

It is essentially:

“A standardized electrical wiring system.”

Best suited for:

Automation control panel

Export equipment

IEC-compliant projects

Systems requiring frequent expansion

Type 2: TD – Structural Modular Terminal Block

TD is fundamentally a structural combination terminal block.

Even though:

It can be assembled in sections

It can be mounted on DIN rail using a base

Its design philosophy is:

More integrated structure

Often optimized for power distribution

Fewer system accessories

More cost-driven design

It is more like:

“A practical wiring component rather than a full DIN system.”

Best suited for:

Power distribution

Higher current connections

Cost-sensitive projects

Simple wiring layouts

Core Insight

Both are modular.
Both can be DIN-mounted.

But:

UKLSG = System-oriented DIN rail terminal block

TD = Structural modular power terminal block

The difference lies in system integration level, accessory ecosystem, and application focus, not simply in mounting method.
