GENERAL PURPOSE RELAY TYPE 158 FEATURES: Type 158 relays are designed for UL Recognition for Motor Control through 240 VAC in accordance with UL Standard 508, Industrial Control Equipment. Provides through air spacing of 1/16 minimum and over surface spacing of 1/8 minimum for 1/3 horsepower motor control applications at 120/240 VAC The Type 158 relay is physically identical to the Type 156 relay. The Midtex Type 158 is recognized under the Component Program of UL 508. UL File E55708.
