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.
