LT Meter Panels
What Is an LT Meter Panel?
An LT Meter Panel is a metering enclosure that contains energy meters (single-phase or three-phase), current transformers (CTs), voltage terminals, and protective devices. It is typically installed at the service entry point of the LT distribution system—between the utility and the consumer's internal distribution panel.
Key Features of LT Meter Panels

| Current Rating | Typically 10A to 630A depending on the load |
| Meter Types | Single-phase / Three-phase energy meters (electromechanical or digital) |
| Material | CRCA steel, powder-coated or stainless steel; also available in FRP/SMC |
| Protection Devices | MCBs, MCCBs, fuses, ELCBs, etc. |
| Current Transformers (CTs) | For metering & monitoring load accurately |
| Sealing Arrangement | Provided to prevent tampering (as per utility guidelines) |
| Busbar System | Copper or aluminum busbars depending on load |
| Enclosure Rating | IP42/IP54/IP65 – for indoor or outdoor use |
| Window/Door Type | With transparent acrylic/glass window for meter visibility |
