Dimensions for reference only; consult factory for details.
Since all rheostats/potentiometers are electro-mechanical devices, they
are subject to mechanical wear and, therefore, have a finite life.
Models H, J, K, L and N are listed under UL Reexamination Service File
No. E-10946 and CSA File No. 21309 unless noted otherwise.
All rheostats are 10% tolerance.
