APPLICATIONS
The CP resistors are suited for use in high ambient
temperatures and also where ease of mounting and
electrical connections are to be made with quick connect
terminals. Model CP-50 is particularly recommended for
automotive electronic ignition ballast, appliance and motor
ballasts and two-speed fans.
STANDARD ELECTRICAL SPECIFICATIONS
* To order the CP-26B, CP-50B and CP-50B-1 without brackets, remove the B
from model number (CP-26, CP-50 and CP-50-1).
