02 / MODELS

Which of the five series

SCB10 / SCB11 / SCB12

Standard cast-resin. The workhorse for commercial, public and residential distribution — best balance of price and lead time.

SCB14 / SCB18

High efficiency for energy audits, green-building credits and tender scoring.

SCBH amorphous

Lower no-load loss — best value where the unit stays energised 24/7 at light load.

SC10 / SC11 (switchgear-matched)

Built to fit the switchgear cubicle; dimensions made to the panel type.

Dry-type earthing transformer

Neutral earthing with arc-suppression coil or low-resistance grounding.

Custom builds

Corrosion, humid, high-altitude and marine environments — assessed to drawing.

Tell us the duty: capacity, voltage ratio, installation (indoor / underground / outdoor) and fire requirements. We run the loss calculation on your actual load profile instead of pushing the most expensive model.

Frequently asked questions

Dry-type or oil-immersed?
Choose dry-type for indoor, underground, populated or fire-sensitive locations. Choose oil-immersed where there is a dedicated substation room and cost or overload capability matters more. Dry-type costs more at the same rating but has no oil, no oil fire risk and less maintenance.
What is the lead time?
Stocked ratings expedited in 7 days; standard orders 15–30 days; custom or export 25–35 days, per contract.
Do I need a temperature controller and fans?
A controller with three PT100 channels plus alarm/trip output is standard. Add fans for high load factor or high ambient; AF cooling allows 1.2–1.5x short-time overload.
Do I need an enclosure?
Not for a dedicated indoor switch room. Use IP20 / IP23 / IP54 enclosures next to walkways, outdoors, or in dusty and humid areas.
Can you build to IEC?
Yes — designed to IEC 60076-11 or customer standards, with 60Hz, local voltage systems, English nameplate and export crating.
