** CA4000 and CA5000 model numbers are calculated from the CA4000 power rating of 4 watts per inch and CA5000 power rating of 5 watts
per inch. The last three digits of the model number are the body length of the resistor in inches (decimal is between the first and second digit).
Example: CA5150 = 1.50 inches x 5 watts per inch = 7.5 watts.

NOTE:
Wirewound CA resistors can reliably function as a fuse and as a resistor. Such components involve compromise between fusing and resistive functions; therefore,
each design should be tailored to the application to ensure optimum performance. Contact factory by using the e-mail address at the bottom of this page for design assistance.
