Low Tension Switchgear [LT]

LT (low tension) switchgear brings together the switching and protection devices of the low-voltage system in one assembly, built to your single-line diagram.

Typically includes

• Air circuit breakers (ACB) and molded case circuit breakers (MCCB)
• Miniature circuit breakers (MCB) and earth leakage circuit breakers
• Off-load isolators and HRC fuses
• Metering, indication and busbar chambers

Where it is used

• Main LV switchboard after the transformer
• Factories, RMG units and industrial plants
• Commercial buildings, hospitals and malls
• Generator and utility incomers with interlocking

How to choose

• Incomer rating from the transformer (about 1.39 A per kVA at 415 V).
• Busbar material and rating for current and fault level.
• Outgoing feeders with spare ways.
• Breaker brands, metering and form of separation.
• Generator interlock or ATS section if needed.

Why buy from Unique Quality Engineering

We build these at our own factory in Demra, Dhaka, to BNBC and IEC standards and Accord–Alliance requirements, using genuine components from ABB, Schneider Electric, Siemens, Mitsubishi and Fuji Electric. Our engineers install, test and commission on site, and we stay on call for after-sales service.

Frequently asked questions

What decides the LT panel price?

Mainly the incomer type, breaker brand, busbar size, number of feeders and enclosure. See our LT panel price guide.

Which incomer do I need for a 1000 kVA transformer?

About 1391 A at 415 V, so usually a 1600 A ACB.

How long does it take to build?

A standard factory LT panel is usually built in a few weeks after the drawings and breaker list are approved.
