Relay>>JRS3 Series Thermal Relay
1.Application
JRS3 thermal relay is suitable for AC 50/60Hz, voltage up to 660V and current up to 100A,general AC motor of long or discontinuous long operation, used as overload protection and hasthe functions of breaking phase protection, temperature compensation, and trip indication. Itcan automatically and manually get back. It can be fixed with contactor CJX1 together, also beindependtly fixed. The product conforms to IEC60947-4-1 stardand.
