All elements are assembled using stainless steel hardware.

Wirewound Power Resistor Element

WIREWOUND POWER RESISTORS

These units feature an open helical wire element wound around a grooved porcelain core. This type of open element will take considerably more overload than enameled type resistors and also cool much quicker as each turn of the wire is exposed to the cool ambient air.

Stamped Grid Power Resistor

STAMPED GRID POWER RESISTORS

The resistor element of a grid resistor consists of stainless steel plates, normally from 24 to 40, connected in series. Slots are stamped into each plate to give a longer current path.

Ribbon Power Resistor

RIBBON POWER RESISTORS

Stainless steel ribbon resistors feature a 4-inch wide stainless steel element that is serpentine formed from one continuous strip nearly thirty feet long.

Smoothwound Power Resistor Element

SMOOTHWOUND POWER RESISTORS

The smoothwound wire element is wound onto a porcelain tube and coated with a refractory cement coating.

ALUMINUM CASE RESISTORS

IP65 case resistors for light industrial and heating applications where space and moisture resistance are critical.
