    Thermal Eletrical Relay JR29 Series Motor Protection Overload Relays

     

    1. Application


    JR29 series thermal overload relay is mainly suitable for A.C.electric power system with volt-age up to 660V, current up to 500A, 50/60Hz. It is generally used for the protection of overloadand phase-lacking in circuits with three-phase induce motors and is often made up electromag-netic starters with CJX8 series A.C. contactors. The product conforms to IEC60947-4-1 stardand.Noter: JR29-16 is manually reset automatic to the other.
