LR9-F73 thermal overload relays,digital thermal relay


LR9-F73 thermal overload relays,digital thermal relay is mainly suitable forA.C electric power system with voltage up to 690V, current up to 630A,In the circuit of 50-60Hz, it is generally used forthe prote-ction.Of overloadand phase-tacking in circuits with three-phase induce motors and is often made up electromagnetic starters with Bseries ACcontaotors.
Note:Jr16 is manual rest,JR85 is automtic Reset.others are manual reset and automatic reset,concretely read(product operation instruction).
