part number to specify

Choose Ohmite’s 210 Type adjustable resistors for

applications requiring settings at different resistance

values. These wirewound resistors are equipped with

an adjustable lug, making them ideal for adjusting

circuits, obtaining odd resistance values and set-

ting equip ment to meet various line voltages. 210

Type resistors feature a hollow core to permit secure

fastening with spring-type clips or thru bolts with

washers. They also offer the durability of lead free

vitreous enamel coating and all-welded construction.

Mounting brackets not included with resistors.

Based on 25°C free air rating. The stated wattage rating applies

only when the entire resistance is in the circuit. Setting the lug at

an intermediate point reduces the wattage rating by approximately

the same proportion. Example: If the lug is set at half resistance,

the wattage is reduced by approx. one-half.
