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 File No. E-10946 and CSA File No. 21309 unless noted otherwise. All rheostats are 10% tolerance. 1-866-9-OHMITE * Int'l 1-847-258-0300 * Fax 1-847-574-7522 * www.ohmite.com * info@ohmite.com 187 Rheostats (Potentiometers) Wirewound Models H, J, G, K, L Max.
