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.
