Industry Pain Points
- A CT that does not fit the busbar window holds up the whole board
- Five suppliers for one switchboard means five lead times and five sets of paperwork
- DIN rail space runs out before the metering is finished
- Revenue metering ways need a different accuracy class from the rest of the board
What Customers Need
- One series that covers every way on the board, from the smallest outgoing to the incomer
- Three mounting methods in the same body so the panel layout is not dictated by the CT
- Sealable covers on the ways that will be billed
- Class 0.2S available without changing supplier
How The Range Is Used
Distribution board with mixed ways
MES or CA frames on the outgoing ways, an MSQ or RCT ring on the incomer, and a TASN three phase body on each moulded case breaker that needs three phase metering.
Revenue metered feeders
ABO in Class 0.5S or 0.2S with the lead seal hole and transparent name plate cover, so the installation stays auditable.
High current risers
ASK plug in frames up to 7500 A or KBU split core frames where the busbar cannot be dismantled.
Frames For This Industry
ABO Current Transformer
Primary current 5 A to 5000 A
Secondary current 5 A, 1 A, 0.5 A, 0.25 A, 0.1 A
TAS Three Phase Current Transformer
System voltage 720 V, 50 to 60 Hz
Test voltage 3 kV for 1 minute
Questions Buyers Ask
Can I standardise a whole switchboard on one series?
Usually yes. MES, CA, MBO, ABO and MSQ are each published as a full frame ladder, so the only thing that changes across the board is the frame size and the ratio.
What do you need from me to quote?
Ratio, accuracy class, burden, secondary current, busbar or cable dimension and the mounting method. A photograph of the existing CT and its rating plate is usually enough.
Do you supply the panel meters as well?
Yes. Demand ammeters, digital panel meters and RS485 transducers come from the same factory, scaled to the CT ratio you order.
