CA4000 and CA5000 model numbers are calculated from the CA4000 power rating of 4 W per inch and CA5000 power rating of 5 W 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 W per inch = 7.5 W.

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
