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 equipment 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.

25% to improve reliability:  
Derating  
Tolerance  
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.
