* Maximum Voltage is based on Ohm’s Law [V=√P*R] as limited by the resistance value of specified product

To calculate max. amps: use the

formula √P/R

Select 270 Type fixed resistors for applications requiring wattage ratings from 12 to 1000 watts.

The 270 Type resistors are equipped with lug terminals suitable for soldering or sturdy bolt con-

nection. 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.

See page 36

for mounting hardware

Suitable for rugged applications, the 270 Type resistors feature all-welded construction and

durable lead free vitreous enamel coating. Mounting brackets not included with resistors.

Power limitations for high resis-

tance values: When resistance

exceeds the resistance values

listed, derate the Power Rating by
