"LT" (low-tension) and "HT" (high-tension) describe the voltage level a panel is built to handle. Choosing correctly starts with understanding where each sits in your electrical system.
What is an LT panel?
LT panels operate below 1000 V and form the working backbone of most buildings — main distribution, sub-distribution, motor control and power factor correction. They use ACB/MCCB switchgear and busbars sized to the load.
What is an HT panel?
HT panels handle medium-voltage distribution upstream of transformers and large loads, with protection relays and interlocking suited to the higher voltage class. They are engineered for the fault levels and safety clearances that medium voltage demands.
Which do you need?
- Distributing power inside a building below 1000 V → LT panels.
- Taking in medium-voltage supply or feeding transformers → HT switchgear is involved.
- Most projects use both, coordinated so protection settings work together.
