270 Series  
Vitreous Enamel Power  
F ꢀ at u ꢁ ꢀ S  
Select 270 Type fixed resistors for applications  
requiring wattage ratings from 12 to 1000 watts.  
The 270 Type resistors are equipped with lug termi-  
nals suitable for soldering or sturdy bolt connection.  
When secure mounting is required, the hollow core  
of these resistors permit fastening with spring-type  
brackets, thru bolts or thru bolts with slotted-steel  
brackets.
