Our edge-coil resistors are manufactured as ‘E’ Type 60mm (2 3/8”) diameter, which are subdivided into E Type Standard, ES, ET, EB, and EP types. There are 15 different current ratings from 12 to 100 Amps and max. 9 physical sizes for each type. We can supply single elements, banked, grouped or enclosure as required.

Edge-coil resistors are supplied as our standard E type with optional mounting configuration, with or without mounting feet and permanent or adjustable tapping terminals to suit our customers needs. 

The standard E Type is most suited for grouping them into banks where the fixing arrangements allow removal of an individual element without disturbing the adjacent elements. Please contact us should you require more information about specifications, or a custom design.

‘HD’ (Heavy Duty) and ‘MD’ (Medium Duty) are 100mm (4”) diameter power resistors.

The HD range, more commonly used in traction and power generation industry have 5 different current rating from 100 to 200 Amps with 4 different physical sizes.
The MD range, most suited for high power load testing have 6 different current rating from 40 to 100 Amps with 2 different physical sizes. Mounting feet can be supplied for individual MD range resistors. All resistors within this group can be supplied with fixed intermediate tapping terminals.
